The construction of smart cities is an important impetus for promoting the development of urbanization. In addition to the technological support, the construction of smart cities should also consider the impact of information technology on city governments, enterprises, and residents' activities and activity space. Based on the analysis of the general situation and consideration of existing problems of the construction of smart cities in China, the authors conclude that the development of smart cities is an inexorable trend to adapt to the strategic transformation of urbanization, upgrading of public services, community development, and solving urban problems. Innovations in geography and their theoretical support function to smart cities are then discussed with regard to the coupling of multiple heterogeneous data, time-space compression, the new mobility paradigm, space of flows, human-nature relationship under new circumstance, and spatiotemporally coordinated development. Also, the innovation research of geography interact with the different systems of smart cities. Based on the research and application of urban geography, we put forward the key aspects of planning and construction of smart cities, including the top design, the distributing of functional zones and spaces, the integration of infrastructure, and rural-urban governance, among others.

The vulnerability framework of the Research and Assessment Systems for Sustainability Program explicitly recognizes the coupled human-environment system and accounts for interactions in the coupling affecting the system's responses to hazards and its vulnerability. This paper illustrates the usefulness of the vulnerability framework through three case studies: the tropical southern Yucatán, the arid Yaqui Valley of northwest Mexico, and the pan-Arctic. Together, these examples illustrate the role of external forces in reshaping the systems in question and their vulnerability to environmental hazards, as well as the different capacities of stakeholders, based on their access to social and biophysical capital, to respond to the changes and hazards. The framework proves useful in directing attention to the interacting parts of the coupled system and helps identify gaps in information and understanding relevant to reducing vulnerability in the systems as a whole.

In the late 1970s and early 1980s, geographical science entered a new stage, which is characterized by the shift of major attention from the nature dominated environmental changes to the human dominated ones, that is, the interactions between natural process, biological process and human activity. All this shows the changing nature of geography is at the core of dramatic changes within ecosphere, the dynamic man land relationship. Unfortunately, it is the dramatic relationship that has led to the continuing destruction of resources bases as well as ecological and environmental bases upon which human being are dependant. Given the global changes, geographers are obliged to carry out theoretical and empirical studies about sustainable development and environmental protection, from both man land relationship and regional perspectives. The central issues to be concerned are the influences of global change on China and rational approaches for China to realize sustainable development. In recent years, Chinese geographers have contributed a lot to the fields of natural environment, territorial planning and regional development, providing scientific analysis and suggestions essential to China's responses to global change and sustainable development. However, the potential advantages of geography in terms of resolution of these critical issues have not been realized so far. To change such a situation, geographers have to make great efforts to synthetic theories and methodologies, giving full recognition to the theoretical studies of man land territorial system. The issues of sustainable development should remain as major concern by China's geographers in a long time. In fact, the efforts to coordinate the man land relationship aim at the realization of sustainable development. Clearly, the theories of man land territorial system should work as important theoretical bases of sustainable development. Therefore, it is a significant task for geographers to enhance the theoretical studies of man land territorial system. The prior issues regarding man land territorial system are as follows: 1) studies on regional differences from systematic perspective; 2) a deeper understanding of the characteristics of man land territorial system; and 3) studies on the approaches for comprehensive integration. Furthermore, the development of methodologies with comprehensive and systematic perspectives, territorial and dimensional perspectives as well as model building and simulation applicable to practice deserves more efforts.

The development of contemporary human geography shows a diverse tendency. Physical science should be the base of human geography, and the tendency of physical science will be the unavoidable choice and unique way for future development of human geography in China. According to the disciplinary property of human geography and the need of Chinese economic social development, the tendency of physical science should not be a passive target but an initiative pursuit. There are two elementary goals. One is building a relatively complete theory system of regional spatial structure. It is necessary to discover new regional spatial structure patterns, construct evolution model of the central place system and find the internal logical relationship among different structure patterns from the perspective of typology and phylogeny. The other is constructing relatively complete methods of spatial analysis. The region can be divided into homogeneous region and functional region, and furthermore be decomposed into three fundamental elements: point, line, and area. The theoretical framework of spatial analysis for human geography in this article is constructed by the technologies to explore and express the spatial coupling inter- and intra-elements. Expanding the accessibility analysis technology, integration of economic models and spatial analysis technologies, construction of the comprehensive system of spatial-temporal spectrum spatial analysis, and discovery of new spatial analysis technologies based on the extension of space concepts, should be the significant fields of spatial analysis for human geography in the future. To achieve these goals, we should establish scientific thinking patterns, integrate resource and environment basis, improve the long period analysis of historical process from the perspective of phylogeny and fully use modern technology such as mathematical model and GIS technology.

In combination with the author's review of frontier issues in human geography in recent years, this paper clarifies that uncovering the spatiotemporal difference rules of human-environment system interaction in the geographic pattern is the highest-level scientific puzzle in modern geography, and is the understanding of key issues which could decide the prospect of future geography. Four practical methods including "process induction, regional comparison, qualitative analysis, logical judgment" until now for integrated human-environment system researches are proposed. Aiming at four frontier fields including regional equilibrium, resources and environment carrying capacity, territorial function, and spatial structure, academic ideas including the driving forces of regional development pattern changes, the impact carrier of natural sphere on human activity sphere, the rules and methods for integrated geographic zoning, and the changing laws of "living-production-ecology" spatial structure, are discussed. Finally, this paper discusses the significance and key issues of regional sustainable development in the framework of "Future Earth", and presents that the integrated method system and basic theoretical system of comprehensive research in complexity science based on "integration of both natural and social sciences" and "interpenetration of both basic researches and decision-making application", will profoundly influence research progress of the process and framework of human-environment system.

人地关系是地理学研究的经典问题,也是中国人文—经济地理学在国际地理学研究中具有突出贡献的命题。人地关系在动态演变过程中不断出现新的时代内涵,如何科学表征中国现代人地关系的状态,是精准认知现代人地关系进而寻求协调人地矛盾路径的基础。基于人地关系地域系统理论,在梳理中国现代人地关系时代特征的基础上,构建人地关系综合评价的理论框架,从人类活动的施压强度、核心资源要素的承压能力、生态环境系统的约束力度以及人—地系统的开放程度4个层面选取表征指标,秉承分级评价、逐级修正的思想,以县级单元为基础对全国层面的人地关系状态进行综合评价。结果发现：中国的人类活动强度具有明显的东西分异性及依托核心城市群布局的特征,而核心资源要素的综合支撑能力空间布局较为分散,且土地、水、核心能矿资源以及人类活动强度四者之间的空间错配度较高,在一定程度上增加了区域人地关系的紧张状态。生态环境系统的约束紧密区多集中在胡焕庸线两侧及青藏高原西南部,全国层面上人—地系统的开放程度不高,开放程度较高的区域主要集中在中国经济发达地区。综合评价结果显示,全国大约85.56%的区域人地关系状态以宽松为主,但是局部地区尤其是东南沿海地区人地矛盾突出,西部地区人地关系相对宽松,但人地系统演进的等级也相对较低。

Relationship is a classic concern of geographical research, which is also a research field where China's human and economic geography has made notable contributions to international geographical research. The connotation of man-land relationship changes constantly during its dynamic evolution process. Therefore, a scientific evaluation on the status of modern man-land relationship in China is the basis for an accurate understanding of it with which paths of coordinating conflicts between man and land can be sought. Based on the territorial system theory of man-land relationship and a review of the new characteristics of modern man-land relationship in China, this study constructs a theoretical framework to make a comprehensive evaluation on man-land relations using the following four indicators: intensity of human activities, carrying capacity of core resources, ecological and environmental constraints, and openness of man-land system. Counties are taken as the basic spatial units in the evaluation. The following results are found: there are apparent differences between eastern and western China in terms of intensity of human activities and the distribution pattern of it follows the layout of core urban agglomerations; the carrying capacities of core resources take on a relatively dispersed spatial distribution; there is a high level of spatial mismatch between land, water, core energy resources, and the intensity of human activities, which intensifies the tension of regional man-land relationship; areas with strong ecological and environmental constrains are concentrated on both sides of the Heihe-Tengchong Line (also known as the Hu Huanyong Line) and in the southwestern part of the Qinghai-Tibet Plateau; overall, the level of openness of China's man-land system is not high, with relatively open areas mainly concentrated in economically developed regions. The evaluation results show that about 86% of the regions in China are faced an unstrained man-land relationship, but noticeable man-land conflicts are found in some areas, particularly in southeastern coastal areas. In the western region of China, man-land relationship is relatively unstrained though the level of man-land system evolution is low.

在越发紧密关联的全球化世界中,如何实现可持续发展日益需要跨系统思维和超区域政策。这首先要求致力于可持续发展研究的学科要提升自身对跨区域资源环境问题的洞察力,因此就有必要推动地理学传统研究框架的适应性创新和变革。远程耦合作为聚焦于“远距离人类与自然耦合系统之间社会经济与环境相互作用”的理论框架,有极大的潜力和优势来促进这一理论创新进程。为了缩小国内外在远程耦合领域的研究差距,论文基于文献研究和笔者对远程耦合框架的理解,从远程耦合的理论建构、经验证据、重点研究领域和研究方法4个方面介绍了该理论框架及其应用进展,并提出3个方面的展望来激发新的研究。综述表明,由于远距离人类活动不断增长以及大尺度自然过程与人类活动的相互作用,在远程连接、全球化和城市化维度上均存在大量远程耦合的经验证据;目前学术界对远程耦合框架的应用主要集中于生态系统服务、远程耦合的社会经济和环境影响及土地变化科学3个方面;同时得益于理论操作化的进展,目前开展远程耦合研究已具备较好的方法支持。基于此,论文认为,为应对新兴的现实科学命题,基于远程耦合框架的地理学研究应当在人地关系网络系统的理论创新、远程耦合动力机制和远程耦合的调控工具集3个方面实现突破。

Achieving sustainable development in an increasingly interconnected globalized world requires cross-system thinking and more integrated regional policy. First, it requires disciplines devoted to sustainable development research to improve their insights into trans-regional resource and environmental issues. Accordingly, it is necessary to promote the adaptive innovation and transformation of the traditional research framework of geography. Telecoupling, as a theoretical framework focusing on socioeconomic and environmental interactions among coupled human and natural systems over distances, has great potential and advantages to facilitate the process of theoretical innovation. In order to narrow the gap between Chinese and international research in the field of telecoupling, we introduce the telecoupling framework and its application progress from theoretical construction, empirical evidence, key research areas, and research methods based on literature review, document analysis, and our own understanding of telecoupling, and further give some suggests. The review shows that there is a large amount of empirical evidence of telecoupling in the dimensions of teleconnection, globalization, and urbanization due to the continuous growth of long-distance human activities and their interaction with large-scale natural processes. Currently, the application of the telecoupling framework in academia mainly focuses on three aspects: ecosystem services, the socioeconomic and environmental impacts of telecoupling, and land change science. Due to the progress in operationalizing the theories, current telecoupling research has been well supported methodologically. We further argue that geographical research based on the telecoupling framework should make breakthroughs in the theoretical innovation of Human-Earth relationship network system, telecoupling mechanism, and telecoupling regulatory tool sets, so that scientific research can keep up with the latest trends and solve the emerging real world problems.

利用中国海关贸易库数据,对计算机上游和下游出口源地的空间格局演变进行对比分析,以面板数据方法揭示产业集聚和政策激励的作用。研究发现：① 计算机上游出口集中在长三角和珠三角,下游出口集中于长三角和成渝,上游出口格局更分散;② 从动态看,上游出口从珠三角逐步向内陆扩散呈现集聚-分散-集聚的过程,内陆地区承载大部分出口增长;下游出口增长态势更为明显,最初集中分布在长三角和珠三角,2010年以后内陆地区增长迅速,成渝成为继长三角后最为重要的集聚区;③ 研究时段集聚经济对计算机上下游制造业的推动作用降低,政策激励的影响显著增加;④ 沿海和内陆计算机制造业发展模式不同,前者的兴起主要是市场化条件下的集聚经济,后者则受到集聚经济和政策激励的共同影响;⑤ 由于产业特征的差异,集聚经济对计算机上游的影响高于下游。在计算机制造业的发展中,要素成本增加造成的集聚不经济和地方政府的政策激励使得集聚效应逐步让位于政策支持。不同区域不同阶段产业对政策的敏感程度并不相同,政策制定应顺应产业演变规律。

The coast areas of China took the lead in developing and exporting computer products based on comparative advantages. However, with the rising of wage, land price and environmental standards, as well as strong incentives of local governments, a large number of enterprises started to relocate to the inland areas of China. Thus, the spatial pattern of Chinese computer manufacturing had changed dramatically. On the base of export data compiled by the Chinese Customs Trade Statistics, this article investigated the spatial patterns of upstream and downstream computer industry during 2004 to 2013. Based on panel data method this research revealed the role of agglomeration economy and incentive policy in affecting the pattern of computer exportation. The results indicate that: 1) The exportation of upstream computer industry is concentrated in the Yangtze River Delta and the Pearl River Delta while the downstream industry is concentrated in the Yangtze River Delta and Chengdu-Chongqing region. The distribution of the upstream industry is more dispersed. 2) From a dynamic perspective, the exportation of upstream computer industry shows agglomeration-scattered-agglomeration feature as it decreased in the Pearl River Delta while increased in inland areas. Exportation of downstream computer industry is initially concentrated in the Yangtze River Delta and the Pearl River Delta. After 2010, the downstream industry grew rapidly and Chengdu-Chongqing region became the second biggest (after the Yangtze River Delta) export areas in 2013. 3) The influence of agglomeration on both upstream and downstream computer manufacturing was reduced while the impact of policy increased significantly. 4) The developing routines of computer manufacturing in the coastal and inland regions are different. The rise of the former is mainly stimulated by agglomeration under the background of marketization, and the latter is influenced by both agglomeration and policy. 5) Due to the difference of industrial characteristics, the impact of agglomeration on the upstream industry is more than the downstream. This article suggests that with the increasing of cost, agglomeration is gradually becoming not economical. Policy development should be consistent with the evolution of agglomeration economy to realize expected economic performance.

城市与乡村是一个有机体,只有二者可持续发展,才能相互支撑。依据人地关系地域系统学说,城乡融合系统、乡村地域系统是全新认知和理解城乡关系的理论依据。针对日益严峻的“乡村病”问题,全面实施乡村振兴,既是推进城乡融合与乡村持续发展的重大战略,也是破解“三农”问题,决胜全面建成小康社会的必然要求。本文探讨了新时代城乡融合与乡村振兴的基础理论,剖析了乡村发展面临的主要问题,提出了问题导向的中国城乡融合与乡村振兴科学途径及研究前沿领域。结果表明：① 城乡融合与乡村振兴的对象是一个乡村地域多体系统,包括城乡融合体、乡村综合体、村镇有机体、居业协同体,乡村振兴重在推进城乡融合系统优化重构,加快建设城乡基础网、乡村发展区、村镇空间场、乡村振兴极等所构成的多级目标体系。② 中国“三农”问题本质上是一个乡村地域系统可持续发展问题,当前乡村发展正面临主要农业生产要素高速非农化、农村社会主体过快老弱化、村庄建设用地日益空废化、农村水土环境严重污损化和乡村贫困片区深度贫困化等“五化”难题。③ 乡村是经济社会发展的重要基础,城乡融合与乡村振兴战略相辅相成,乡村振兴应致力于创建城乡融合体制机制,推进乡村极化发展,按照产业兴旺、生态宜居、乡风文明、治理有效、生活富裕的要求,构建乡村地域系统转型—重构—创新发展综合体系。④ 乡村振兴地理学研究应着眼于乡村地域系统的复杂性、综合性、动态性,探究以根治“乡村病”为导向的新型村镇建设方案、模式和科学途径,为实现新时代中国乡村振兴战略提供理论参考。

Cities and villages are components of a specific organism. Only the sustainable development of two parts can support the prosperous development as a whole. According to the theory of man-earth areal system, urban-rural integrated system and rural regional system are the theoretical bases for entirely recognizing and understanding urban-rural relationship. To handle the increasingly severe problems of "rural disease" in rapid urbanization, accelerating rural revitalization in an all-round way is not only a major strategic plan for promoting the urban-rural integration and rural sustainable development, but also a necessary requirement for solving the issues related to agriculture, rural areas, and rural people in the new era and securing a decisive victory in building a moderately prosperous society in all respects. This study explores the basic theories of urban-rural integration and rural revitalization and analyzes the main problems and causes of rural development in the new era, proposing problem-oriented scientific approaches and frontier research fields of urban-rural integration and rural revitalization in China. Results show that the objects of urban-rural integration and rural revitalization is a regional multi-body system, which mainly includes urban-rural integration, rural complex, village-town organism, and housing-industry symbiosis. Rural revitalization focuses on promoting the reconstruction of urban-rural integration system and constructs a multi-level goal system including urban-rural infrastructure networks, zones of rural development, fields of village-town space and poles of rural revitalization. Currently, the rural development is facing the five problems: high-speed non-agricultural transformation of agriculture production factors, over-fast aging and weakening of rural subjects, increasingly hollowing and abandoning of rural construction land, severe fouling of rural soil and water environment and deep pauperization of rural poverty-stricken areas. The countryside is an important basis for the socioeconomic development in China, and the strategies of urban-rural integration and rural revitalization are complementary. The rural revitalization focuses on establishing the institutional mechanism for integrated urban-rural development and constructs the comprehensive development system of rural regional system, which includes transformation, reconstruction and innovation in accordance with the requirements of thriving businesses, pleasant living environments, social etiquette and civility, effective governance, and prosperity. Geographical research on rural revitalization should focus on the complexity and dynamics of rural regional system and explore new schemes, models and scientific approaches for the construction of villages and towns, which are guided by radical cure of "rural disease", implement the strategy of rural revitalization polarization, construct the evaluation index system and planning system of rural revitalization, thus providing advanced theoretical references for realizing the revitalization of China's rural areas in the new era.

自时间地理学和活动分析法引入中国以来的近20年间,时空间行为研究已经成为中国城市地理学的重要领域。中国时空间行为研究关注城市空间重构的描述与解释,试图从行为角度解释中国城市社会转型,强调转型期中国城市空间与居民个体行为之间的互动关系,重视日常生活、生活质量、社会公正、低碳社会、智慧城市等热点问题,探索在城市交通、旅游和城市规划等领域中的实践应用。中国时空间行为研究已经形成了以解读城市转型为目标、以规划应用为导向的鲜明特点,为理解中国城市制度与空间转型背景下人类行为模式的复杂性和多样性提供了一个全新的视角。但是,中国时空间行为研究依然面临着理论发展滞后、实践应用需要突破等挑战。本文是对时空行为研究近年来发展的综述性文章,从数据采集与分析方法演进、实证研究与规划应用进展等方面回顾了近20年来中国城市时空间行为研究的最新进展,致力于推动不同学科领域之间的交流和时空间行为研究自身的发展。

As a unique perspective for understanding the complex relationships between human activities and urban environments in space and time, the space-time behavior approach has become an influential methodology in China's urban geography since 1990s. Aiming at promoting communications and exchanges among urban geographers in different contexts, this article provides a critical review of space-time behavior research in China. Ever since time geography and activity-based model were introduced to China's urban geography, space-time behavior research in China has benefited from the fruitful theoretical and methodological progress made in Western geographical research. On one hand, GPS and mobile phone tracking technologies have been integrated into activity-diary surveys to collect more accurate and real-time activity-travel information. On the other hand, advanced statistical models and geocomputational and 3D geovisualization methods have been adopted in more recent empirical literature in China. Yet, while Chinese urban geographers have made more methodological progress in data collection and analytic tools thanks to the development of GPS and GIS technology, theoretical development still lags behind. However, space-time behavior research in China, with planning-oriented characteristics, offers a unique framework for understanding urban transformation in China. It has become a new perspective for understanding the complexity and diversity of human behavior patterns in the transitional cities in China. In other words, space-time behavior research tries to describe and interpret urban spatial structures and spatial reconstructing in urban China from the perspective of individuals' behaviors. The impacts of danwei-based urban spatial organization and its disappearance, as well as the impacts of suburbanization on individuals' daily activities, have been studied carefully. Especially, this approach emphazes how spatial restructuring impact individuals' daily life experiences, which in turn are related to the issues such as life quality, social equity and environmental sustainability. Urban geographers in China have begun to apply the space-time activity approach to the socio-spatial issues in the cities by focusing on daily-activity experiences of low SES (socioeconomic status) populations. And the development of the low-carbon city movement in China has prompted the application of the space-time behavior approach in understanding the impacts of land use characteristics on travel-related carbon- dioxide emissions through individuals' travel decisions. At the same time, planning practices based on the space-time behavior approach is carried out in urban transportation, tourism, and urban planning. The space-time behavior approach has become a very useful human-oriented approach to land use and transportation planning in China. The article concludes by discussing key theoretical and practical challenges for future development of space-time activity research in China.

Environmental governance is more effective when the scales of ecological processes are well matched with the human institutions charged with managing human-environment interactions. The social-ecological systems (SESs) framework provides guidance on how to assess the social and ecological dimensions that contribute to sustainable resource use and management, but rarely if ever has been operationalized for multiple localities in a spatially explicit, quantitative manner. Here, we use the case of small-scale fisheries in Baja California Sur, Mexico, to identify distinct SES regions and test key aspects of coupled SESs theory. Regions that exhibit greater potential for social-ecological sustainability in one dimension do not necessarily exhibit it in others, highlighting the importance of integrative, coupled system analyses when implementing spatial planning and other ecosystem-based strategies.

回顾传统城市研究范式,指出其“重宏观社会经济发展研究、而轻微观居民个体需求分析”这一问题,在此基础上,综述了城市研究领域的大数据热潮,进而抛出“数据亦或人本驱动?”的争论;从大数据自身的缺陷、智慧社会的到来及未来城市发展维度3个方面分析未来城市研究数据和人本之间的关系,提出应遵循“人本驱动、数据支撑”的研究范式,扩展了“人本驱动”的内涵。最后,从城市居民生活（生活圈打造、社会网络构建、满足生命周期需求）、企业生产（人才流动网络构建、产业链打造、营销模式转变）、政府管治（数据共享与融合、社会服务供应、公众参与机制创新）3个方面提出了未来城市研究的新框架。

Technological innovation is constantly changing the process of urban development, and the emergence of big data has attracted great attention of urban researchers. Some people believe that data will become the main driving force of future urban research. However, the development stage of human society and the historical transformation of urban research indicate the humanistic trend of future urban development. So, are future urban studies data driven or human-oriented driven? What is the relationship between them and the direction of future urban research? Firstly, this article reviews the traditional urban research and points out the limitations of methodological and data usage, which paid more attention on social-economic development instead of individuals’ needs. Secondly, it summarizes the big data booming in urban research field, and then put forward the argument of “data driven or human-oriented driven?”. Thirdly, the relationship between data and human-oriented in future urban research is analyzed from 3 aspects: the limitations of big data, the arrival of smart society and the trend of future urban development. Fourthly, the research paradigm of “human-oriented driven and data supported” is proposed. Finally, it also builds a new framework of future urban research from three aspects of residents' life, enterprise production and government governance.

This paper combines the one-week bus smart card data (SCD) and one-day household travel survey as well as the parcel-level land use map for identifying jobs-housing places and commuting trips in the Beijing Metropolitan Area with an area of 16,410 square kilometers. The identification result is aggregated in the bus stop and traffic analysis zone (TAZ) levels, respectively. In particular, commuting trips with commuting time and distance attached from three typical residence communities and those to five typical business zones are mapped and compared with each other to analyze commuting patterns of Beijing. The identified commuting trips are compared with those in the household travel survey in terms of commuting time and distance, indicating that our results are coincident with the survey significantly. Our approach is proved to have its potential in identifying more solid identification result based on rules extracted from existing surveys or censuses.

“腾讯迁徙”大数据基于位置服务,实时、动态、完整、系统地描述了用户日常出行活动的轨迹。通过采集“腾讯迁徙”数据平台中2017年国庆-中秋长假期间国内299个城市之间的逐日人口流动数据,分“出行期、旅途期、返程期”3个时间段,利用复杂网络分析方法,从人口流动集散层级、集散网络体系的分层集聚、人口流动空间格局、网络空间特征等角度分析各时间段城市间的人口流动特征与空间格局。结果表明,腾讯迁徙大数据直观地揭示了国庆-中秋期间中国各地级城市间人口的迁移规律,3个时段人口的净流入均呈现十字形骨架支撑的菱形分布,人流集散中心主要集中在京津冀、长三角、珠三角和成渝四大城市群,与城市等级有较强的一致性。人口流动集散体系呈明显的分层集聚,城市行政级别的高低与人口流动影响力存在一定的正相关关系,大部分城市人口流动处于“相对平衡”状态。人口流动空间格局呈现出明显的核心-边缘结构,大理-鹤岗一线是人口流动强度空间分布的显著分界线,以此线为界,城市网络呈现东密西疏的分布特征和东部并联、西部串联的网络关联特征。人口流动网络总体表现出“小世界”网络特征,局部具有较明显的“社区”结构特征,聚为2个国家级、2个区域级和3个地区级社区。

Population migration, social check-in, vehicle navigation, and other spatial behavior big data have become vital carriers characterizing users' spatial behavior. The big data used in this paper were collected from the locations provided by hundreds of millions intelligent mobile phone users through Location Based Service (LBS) Tencent Migration data platform, and were displayed by means of real-time heat map which indicates user’s moving trajectory in China. "Tencent Migration" big data can real-timely, dynamically, completely and systematically record population flow routes using LBS device. Through gathering residents daily mobility among 299 cities in China during the period of "National Day-Mid-Autumn Festival" (NDMAF) vacation (from September 30 to October 8) in 2017 in "Tencent Migration" and defining three periods with "travel period, journey period, return period", this paper is designed to analyze and explore the characteristics and spatial patterns of daily flow mobility cities from the perspective of population daily mobility distribution levels, flow distribution layers network aggregation, spatial patterns and characteristics of the complex structure of the flow network. Results show that "Tencent migration" big data clearly discovers the temporal-spatial pattern of population mobility in China during the period of NDMAF. The net inflow of population showed a diamond-shaped pattern with cross frame support in each period, with the four nodes of Beijing, Shanghai, Guangzhou and Xi’an. Main mobility assembling centers are distributed in the urban agglomerations of Beijing-Tianjin-Hebei, Yangtze River Delta, Pearl River Delta and Chengdu-Chongqing, and those centers have strong coherence with those urban hierarchies. There is a positive correlation between the level of urban administration and the influence of population flow. Most cities are in a state of "relative equilibrium" in the population flow, and clear hierarchical structure and level distinction can be identified. Spatial patterns of population mobility present obvious core-periphery structures. The Dali-Hegang line exhibits a significant network of spatial differences in terms of boundary divisions. In this context, the spatial distribution of urban network could be summarized as "dense in the East and sparse in the West", and the core linkages of urban network could be characterized as "parallel in the East and series in the West". The whole network exhibits a typical "small world" network characteristic, which shows that China's urban population flow network has high connectivity and accessibility during the period of NDMAF. The network has a distinct "community" structure in the local area, including 2 national communities, 2 regional communities and 3 local-level communities.

信息技术影响下的城市区域空间结构变化得到了国内外学者的关注。本文以新浪微博为例, 从网络社会空间的角度入手, 对中国城市网络发展特征进行了研究。研究表明:微博社会空间视角下的中国城市网络存在着明显的等级关系与层级区分, 城市的网络连接度与城市等级表现出了相对一致性。根据城市网络层级与网络联系强度, 东部、中部、西部3 大区域板块的网络联系差异明显, 东部地区内部的联系, 以及东部与中部地区和西部地区的联系几乎构成当前网络体系中的全部。城市网络呈现出分层集聚现象, 具体表现为“三大四小”发展格局, 即京津冀区域、珠三角区域、长三角区域、成渝地区、海西地区、武汉地区、东北地区。高等级城市在整个城市网络中处于绝对支配地位, 北京以突出的优势成为全国性的网络联系中心, 而上海、广州、深圳则成为全国性的网络联系副中心。

The change of urban regional spatial structure influenced by information technology has become a hotspot of research at home and abroad. This study tries to analyze China's city network characteristics from the social network space perspective by using Sina microblog as an example. The result shows that China's city network based on the micro-blog social space has a clear hierarchical structure and level distinction. Firstly, the result shows the existence of regional characteristics, performance as a visible regional development pattern which contains "Three Main-regions and Four Sub-regions" according to the analysis of the level distinction in the city network and the connection rate between cities. Specifically speaking, the three main regions contain the Beijing-Tianjin-Hebei region represented by Beijing, Pearl River Delta region represented by Guangzhou and Shenzhen, and the Yangtze River Delta region represented by Shanghai, Hangzhou and Nanjing. The four sub-regions contain Chengdu-Chongqing region, west coast of the Taiwan Straits region represented by Fuzhou and Xiamen, Wuhan region represented by Wuhan and Changsha, Northeast China represented by Shenyang, Harbin and Changchun. Secondly, the result shows there is a significant difference of the network links among Eastern, Central and Western China. Links within Eastern China and the links between Eastern, Central and Western China constitute almost all of the current network systems. It is also found that the high-level cities have an absolute dominance in the city network pattern, and that Beijing is the contact center in China's city network, with an overwhelming advantage. Shanghai, Guangzhou and Shenzhen are the sub-contact centers in the China's city nework.

Urban signs characterize the state of development and operation of a city, including construction conditions of built environment,driving force of urban economic and social development, operational status of facilities and urban activities of individuals in the city, etc. The diagnosis of urban signs equals to the health examination of urban development and operation, by which sticking points are recognized. A set of reliable and practical urban diagnostic indices is required not only to comprehensively reflect correlative sub urban systems that are static or dynamic, but also illustrate the status of urban system through quantitative methods and geo-visualization. Using traditional data and big data from different sources, this paper constructs a system of diagnostic index of urban signs based upon the integration of urban activity-travel system, urban population system, urban operation system, and urban environment system. The diagnostic index system is decomposed into 4 dimensions including fundamental force, driving force, pressure and vitality. The fundamental force index is used to describe basic attributes of land use and population; the driving force index reflects the state of development of spatial units through development of enterprises and quality of the environment; the pressure index is used to monitor the running status of the urban system, and as such, it plays a role in risk-evaluation and risk-warning; the vitality index reflects the real vitality of the spatial units by demonstrating the dynamic characteristics of the activity system and flows in time and space. 12 spatio-temporal scales are acquired through intersection of 4 levels of the spatial units（municipal Shanghai, district, Jiedao, census tract）and 3 levels of temporal scales（annual,daily and real time levels）. The index weight is determined by fuzzy hierarchy analysis. Taking April 6, 2016 as an example, we calculate both comprehensive and dimensional diagnostic index of urban signs of Jiedaos (subdistrict that is sub-divided into several residential communities or neighbourhoods) in Shanghai and elaborate on how the diagnostic index of urban signs corresponds to actual state and facilitates detection of urban problems. Results show that comprehensive diagnostic index varies slightly while considerable variations emerge in diagnostic index of each dimension. Fundamental force index, driving force index and vitality index decline gradually from inner city to suburbs. On the contrary, pressure index increases from inner city to suburbs. Through visual and real-time analysis and evaluation, the diagnostic index of urban signs has huge potential for implementation in urban grid management, pressure warning and other needs of urban governance.

党的十九大报告明确的“智慧社会”建设目标,对当前国土空间规划工作的开展提出了新的要求。如今,以互联网、大数据、云计算等为主的信息化技术赋能是当前国土空间规划智慧化的主要动力与发展重点,而如何理解并推进智慧社会发展则是智慧编制与实施国土空间规划的重要基础。人地关系和地域生命有机体理论是智慧社会下国土空间规划与治理的理论与方法基础,需要从信息化赋能向包含技术赋能与创新赋能的综合赋能理念转变,探讨智慧国土空间规划的总体思路,进而构建以生态文明为基础、以人为本为核心、技术集成应用和制度创新为支撑的智慧国土空间规划框架（EPTI）,并探讨规划编制的智慧化以及规划实施的智慧化。

The Communist Party of China's 19th National Congress Report has clearly set the goal of "smart society" and put forward new requirements for the current development of territorial spatial planning. Nowadays, the empowerment of information technology based on the Internet, big data, cloud computing, etc. is the main driving force and development focus of the current practices of smart territorial spatial planning. How to understand and promote the development of smart society is the foundation of the compilation and implementation of smart territorial spatial planning. This paper emphasizes the importance of human-land relationship and the theory of urban life organism to the planning and governance of territory in a smart society. It points out that the overall conceptualization of smart territorial spatial planning should be transformed from informational empowerment to comprehensive empowerment, which includes technological empowerment and innovative empowerment. The paper constructs a smart territorial spatial planning framework-EPTI-based on the ideas of ecological civilization, people-oriented, technology integration application and institutional innovation, and discusses the paths toward smart compilation and implementation of territorial spatial planning.

在智慧城市建设上升为国家战略的大背景下,以城市人口、经济、资源、环境等历史数据分析为基础的传统城市空间发展模型面临着数据来源与研究框架的革新。本文首先阐述了智慧城市与可持续发展理念产生的时代背景、概念内涵、相互关系,进而在梳理国内外可持续发展视角下的城市模型相关研究基础上,认为智慧城市建设为城市模型研究提供了更为精细、实时、全面的数据来源,拓宽了城市模型研究的时空尺度,并在城市系统运行模拟与仿真方面提供新的技术手段。本文从城市数据监测采集与互联共享、城市系统运行问题梳理与综合分析、城市空间发展模拟仿真与决策评估、城市空间发展规划体系4个层面尝试构建基于智慧城市的可持续城市空间发展模型总体架构,对于丰富城市可持续发展研究理论框架,指导智慧城市空间规划与建设实践具有重要意义。

Under the background that smart city construction has become a national development strategy, traditional urban spatial development models based on the analyses of historical data of population, economy, resource, and environment need to incorporate new sources of data and innovative research framework. This article first discusses the background and connotation of, and relationship between smart city and sustainable development, and then summarizes the Chinese and international research on sustainable urban spatial development models. It concludes that smart city construction provides finer, comprehensive, and real-time data and broadens the spatial and temporal scales of models for urban system modeling, as well as offers new technical means for the simulation of urban system operation. Based on the above, this article presents the overall architecture of an sustainable urban spatial development model based on the construction of smart cities. The model contains four parts that: (1) monitor, collect, and share urban data; (2) decipher and analyze urban operation problems; (3) simulate urban spatial sustainable development and evaluate the related policies and decisions; and (4) design the urban spatial development planning system based on the construction of smart cities. It is important for enriching the theoretical framework of urban sustainable development and guiding the spatial planning and construction practices of smart cities that aim at sustainable development for the ultimate goal.

Quite a number of smart-city initiatives from around the world have been analyzed and documented, and a growing body of academic knowledge is evolving around the phenomenon of the smart city. Smart-city government is seen as an important driver for developing a smart urban environment. The eCityGov Alliance in the Pacific Northwest of the USA represents a special case of a successful smart-city collaboration between nine neighboring municipalities, which combined forces to provide smart services to citizens and businesses that no single municipality could have provided alone. Developing and maintaining a collaborative governance model appears as the most important key success factor in such multi-jurisdictional smart-city undertakings. This study investigates the governance model of the eCityGov Alliance and its opportunities, and potential pitfalls. It concludes that the eCityGov Alliance can serve as a role model for such multi-jurisdictional smart-city initiatives.

同近年国外人文地理学呈现人文化趋势相比,中国人文与经济地理学秉承吴传钧先生关于人文与经济地理学是研究自然圈与人文圈相互作用下、人类活动分布格局形成和演变规律的一门交叉学科的定位,形成了以不同空间尺度的地域、重要的生产生活领域、以及典型的地域空间类型的可持续发展时空规律作为研究指向的中国人文与经济地理学主流学派。吴先生提出的“人地关系地域系统”理论不仅为人文与经济地理学,而且是为整个地理学的综合研究提供了重要的理论基石。地域功能性、系统结构化、时空变异有序过程、以及人地系统效应的差异性及可调控性,是该理论的精髓,这与“未来地球”研究计划的前沿思想完全契合。近10年来,以城镇化科学模式、主体功能区划、一带一路路线图、京津冀城市群、农村空心化和精准扶贫、东北振兴与资源型城市转型、行政区划优化等为研究对象,发展了人文与经济地理重要的可持续过程、地域功能形成和综合地理格局有序化规律、城市群形成演化机理及其资源环境效应、问题地区可持续生命周期与振兴路径、地缘政治地缘经济和区域间相互作用关系、人文界线对可持续发展的影响等理论方法。人文与经济地理学科建设取得重要进展,应用成果对近年来中国生态文明建设和可持续发展产生了重要影响。中国人文与经济地理学在全球范围内发展态势最佳、总体水平领先,以此告慰吴传钧先生,并以此纪念吴传钧先生百年诞辰。

Compared with the increasingly obvious humanistic tendency in foreign human geography, China's human and economic geography still follows Academician Wu Chuanjun's theory, with human and economic geography as an interdisciplinary subject which is the study of the formation and evolution of the distribution pattern of human activities under the interaction of natural circle and human circle. And China's mainstream school on human and economic geography has been formed with studies on spatio-temporal rule of sustainable development on territories with different space scales, territories with important production and living, and territories with typical geospatial patterns as the main research points. "Territorial System of Human-environment Interaction", developed by Academician Wu Chuanjun, is the important theoretical foundation not only for human and economic geography, but also for the comprehensive research on geography. The essence of the theory, which includes territorial functional, system structured, orderly process for spatio-temporal variation, and the difference and controllability of human-environment interaction system effect, is entirely harmonious with the forefront of thought of the "Future Earth" studies program. In recent decade, with scientific mode of urbanization, major function oriented zoning, road map for the Belt and Road Initiative, Beijing-Tianjin-Hebei urban agglomeration, rural hollowing and targeted poverty alleviation, revitalization of Northeast China and transformation of resource-based cities, and administrative area optimization as the main research objects, theoretical methods have been developed in the aspects of important sustainable process of human and economic geography, territorial function formation and ordering rules for comprehensive geographical pattern, formation and evolution mechanism of urban agglomeration and its resources and environmental effects, sustainable life cycle and the revitalization of the path for problem areas, the interaction between geopolitics, geo-economy and regions, and effect of cultural boundaries on sustainable development. China's human and economic geography has made great progress in discipline development, and the application results have produced profound influences on the ecological civilization construction and sustainable development in recent years. With decades of hard work, China's human and economic geography has reached a world-class advanced level, so as to console the soul and spirit of Wu Chuanjun on the occasion of commemoration of the centenary of his birth.

Man-land relationship includes human dependent upon nature and human activity to nature. Contents of man-land relationship are changed with development of human society. Man-land relationship research is the basis for development of modern geography. Various schools of geography such as determinism, possibilism, cultural landscape and human ecology are focusing studies on man-land relationship. The earth system science should carry out interdisciplinary studies between natural and human sciences, to reveal interaction between man and nature as well as the corresponding countermeasures. Developments of information techniques and knowledge economy bring about new opportunities and challenges for human society. Characteristics of man-land relationship in information era differ from those in industrial era. The way and intensity of interaction between human activities and nature will be obviously different. The understanding to nature will be systematically deepened, and ideas of time and space are changing in information era. Knowledge and techniques are becoming main driving forces for social and economic development. Owing to the entirety of the earth, the complexity, protracted nature and potentiality of the interactions among various spheres of the earth, many global environmental issues, such as climate warming, ozonosphere depletion, environmental pollution, etc., are becoming the foci of the countries and public concern throughout the world. The realities impel us to learn lessons and experience accompanied with the traditional development models and to explore new development models for human society. Man-land relationship research covers extensive domains. The hotspots of both global environmental change and sustainable development are closely related to man-land relationship. Global environmental changes have been arisen from slow accumulation process of human impact, and sustainable development is a new development model, which has been obtained by self-examination to development course and model of the human society.The main frontiers of man-land relationship research include the following issues: global environmental change and its regional response, regional sustainable development and mechanism regulation of man-land relationship, studies on social ecological and environmental ethics, etc.

In the past 30 years, the theory of human-earth areal system has played an important support and guidance role in promoting the comprehensive research, disciplinary development and serving national strategic decision of geography. This study analyzes the scientific connotation and era value of human-earth areal system, explores the types and environment of modern human-earth system, and puts forward 'human-earth sphere' and the main contents and frontier fields of human-earth system science. The results show that: 1) The modern human-earth system is characterized by complexity, regionalism and dynamicity. The processes, pattern and comprehensive effect of human-earth interaction are undergoing profound changes, and the human-earth system on the surface of the earth has become the critical content and important theme of modern geosciences. 2) To scientifically understand and effectively coordinate the human-earth relationship, it is urgent to explore the coupling pattern and mechanism of human-earth relationship and to analyze the type, structure and dynamic mechanism of human-earth areal system. Based on the urban-rural relationship, the human-earth areal system can be divided into urban regional system, urban-rural integration system and rural regional system. Furthermore, the rural regional system is subdivided into agricultural system, village system, rural system and township system. 3) Modern human activities strongly affect the human-earth system on the surface of the earth, forming a new surface with the coupling and interaction between human and earth. In essence, it is a natural-economic-technological synthesis or human-earth coordination. They are also the main contents of deepening the researches on the coupling of human-earth system and supporting decision-making for coordinated development of human-earth system. 4) Human-earth system science or human-earth science is a new interdisciplinary subject which studies the coupling mechanism, evolution process and complex interaction effect of man earth system. It is the deep intersection and focus of modern geographic science and earth system science. Taking the modern human-earth sphere system as the research object, it is committed to exploring the state of human activities transforming and affecting the surface environment system, the interaction and coupling law of human-earth system, the formation mechanism and evolution process of human-earth coordination.Human-earth system coupling and sustainable development is the core of human-earth system science. Inheriting and innovating the theory of human-earth areal system and developing the human-earth system science will highlight the subjectivity of human on the earth surface, the process of human-earth coordination and the strategy of sustainable development, thus providing scientific guidance for the coordination of human-earth system and sustainable development decision-making.

地理系统主要研究地球表层人与环境相互作用的机理,强调人地关系、自然和人文要素的综合,即人地耦合系统。地理系统在国土空间中的应用主要由地理决策、地理模拟、地理工程所组成,并且相互作用构成了地理治理。国土空间是自然与人类所共同实践的物质载体,人类被自然所塑造的程度并不亚于自身塑造自然的程度,以人地耦合系统为核心的地理系统理论成为国土空间规划与整治修复的理论基础。基于人地耦合系统的国土空间重塑最终以地理治理的形式反映在人类作用于自然环境的各种活动中。经过改革开放40年的发展,中国国土空间已基本形成了较为稳定的格局,形成了经济区、贫困区、小城镇为主的三种形态空间。中国的城镇化发展与发达国家有所不同,是城市化、城镇化、乡村化“三化耦合”并存的状态。必须重视泛第三极、环中国南海、东北亚—北极等以“一带一路”全球空间为基础的战略区域研究。基于人地耦合系统理论与国土空间价值均衡理论,国土空间重塑的基础科学问题是人地耦合系统演化机理与驱动机制。国土空间规划可以划分为三种类型：发展型规划、控制型规划和修复型规划。国土空间的保护与治理包括以土地利用为核心的国土空间全域整治,以生态文明为核心的国土空间系统修复,以社会和谐为核心的国土空间综合治理。人地耦合系统最终的发展目标是形成人类与自然相互作用的命运共同体。

按照地理学科发展趋势,对城镇化与生态环境耦合的研究将由定量描述转入动态模拟。目前,城镇化与生态环境耦合动态模拟模型呈现多元化。论文系统梳理了其中4类常见的动态模拟模型,包括城镇化与生态环境耦合系统动力学模型、基于人工智能算法的城镇化与生态环境耦合动态模拟模型、基于土地利用变化的城镇化与生态环境耦合动态模拟模型以及基于多模型集成的城镇化与生态环境耦合复合模型。主要结论如下：系统动力学模型被广泛应用于城市复杂系统、城市转型和可持续发展以及城镇化与生态环境单要素耦合的动态模拟之中,但存在空间解释不足以及忽视系统自适应性等问题;人工智能算法(ANN和BN)在自学习、自组织、自适应系统或不确定性系统模拟中具有显著优势,并被应用于城市扩张、环境变化、资源需求以及生态脆弱性的识别之中,但应用面相对狭窄且限制条件偏多;土地利用变化模型(CLUE/CLUE-S、CA和MAS)局限于从土地城镇化视角模拟城镇化与生态环境耦合;基于多模型集成的复合模型实现了各模型之间的优势互补,已成为城镇化与生态环境耦合动态模拟模型的发展趋势。今后,应从技术和理论2个层面实现城镇化与生态环境耦合动态模拟模型的进一步发展,并加强对微观过程的模拟。

The development trend of geographical science indicates that the research on urbanization and ecological environment coupling will move from quantitative description to dynamic simulation. At present, the dynamic simulation models of urbanization and ecological environment coupling are diverse. This article reviewed and summarized four common types of models, including system dynamics model, artificial intelligence algorithm, land use change model, and composite model. The main conclusions are as follows: 1) System dynamics models are widely used in the dynamic simulation of urban complex nonlinear systems, urban transition and sustainable development, and urbanization and ecological environment elements coupling. However, spatial interpretation is insufficient and system adaptability is ignored. 2) Artificial intelligence algorithm has significant advantages in simulating self-learning, self-organizing, and adaptive systems, as well as uncertain systems. It is applied to identify urban expansion, environmental change, resource demand, and ecological vulnerability, but the application range is narrow. 3) Land use change models are limited to the simulation of urbanization and ecological environment coupling under the condition of land transfer to urban use. 4) To achieve complementarities between the various models, it has become a trend to develop composite models based on multi-model integration. In the future, we should develop dynamic simulation models from both the technical and theoretical aspects, and strengthen the simulation of microscopic processes.

Mega- urban agglomerations in China play a vital role in both national economic development strategies and national new-type urbanization, and undertake important historical responsibility with the world economic center transfer to China. However, they suffer a series of increasingly serious eco- environmental problems in the process of development. Thus,studies on the interactive coupled effects between urbanization and eco-environment in megaurban agglomerations are the frontier areas and high priority tasks in the earth system science for the future ten years. This paper analyses the basic theory frame of the interactive coupled effects between urbanization and eco- environment in mega- urban agglomerations systematically. In theoretical aspect, based on the nonlinear relationship and coupling characteristics of the natural and human elements in mega- urban agglomerations system, we could estimate the interactive coercing intensity, nearcoupling and telecoupling mechanism ofthe inside and outside mega-urban agglomerations system after scientific identification of the key elements, and then form the basic interactive coupling theory. Moreover, we could build a spatio- temporal coupling dynamic model, which is integrated with multi- elements, multiscales,multi-scenarios, multi-modules and multi-agents. The model will be used to develop the intelligent decision support system for urban agglomeration sustainable development. In methodology aspect, the mega- urban agglomeration is regarded as an open complex giantsystem. We should establish the standardized shared database for exploring the interactive coupled effects between urbanization and eco- environment. Then using new technology for analyzing big data and the integration methods incorporating of multi- elements, multi- scales,multi- targets, multi- agents, multi- scenarios and multi- modules, we can build a methodology framework to analyze the complex interaction coupling between urbanization and ecoenvironment. The technical route is to analyze spatiotemporal evolution characteristics, identifythe key elements, interpret coupling relationship, reveal the mechanism of coercing effect, find the general rules, filtrate the control variables, solve the critical thresholds, conduct regulation experiments, simulate different scenarios, propose an optimized schemes, and achieve national goals. Furthermore, we could put forward the overall optimization scheme. In general, this research could provide theoretical guidance and method support for the transformation and sustainable development in mega-urban agglomerations.

Smart technology-in its many facets-is often critiqued within geography in ways that parallel the critiques of quantitative geography in the 1960s and GIScience in the 1990s. In this way, both the development of "smart" technology itself and its criticisms are the latest chapter in a long-standing disciplinary debate around quantification and technology. We reevaluate this history and argue that quantitative methodology and its theoretical critiques are not as incompatible as often claimed. To illustrate how we might address this apparent tension between theory and quantitative methods, we review how both approaches conceptualize one of geography's core concepts-space-and highlight opportunities for symbiosis. Although smart technologies can further orthodox positivist approaches, we argue that the actual practice is more nuanced and not necessarily absolute or totalizing. For example, recent computational work builds on critical geographic theories to analyze and visualize topological and relational spaces, relevant to topics such as gentrification and segregation. The result is not a geography in which smart technology and algorithms remove the need for human input but rather a rejoinder in line with the recent resurgence of a critical quantitative geography. In short, the result is a geography where social theory and the human intellect play a key role in guiding computational approaches to analyze the largest, most versatile, most and relevant data sets on social space that we have ever had. Key Words: geocomputation, GIScience,smart technology, space, spatial science.
