    Biomass carbon density is one of the important features of carbon sequestration ability in ecological system. To describe the characteristics of biomass carbon density in alpine grassland in the “Three-River Headwaters” region, above ground biomass, living root biomass, dead root biomass and their carbon content in black soil land and natural grassland were measured. The results showed that the aboveground biomass in black soil land was higher than the aboveground biomass in degraded artificial grassland and natural grassland; but the living root biomass and dead root biomass in black soil land were lower than the living root biomass in degraded artificial grassland and natural grassland. The total biomass carbon density in degraded artificial grassland, black soil land and natural grassland was 719.47, 706.57 and 2 233.09 g/m2, respectively. Grassland degradation not only changed ecosystem biomass allocation, but also changed the carbon density distribution in aboveground vegetation, living roots and dead roots. Root carbon density in degraded artificial grassland and natural grassland accounted for more than 90% of the total biomass carbon density, while the roots carbon density in black soil land accounted for 79.41%. The variation of carbon density in living roots was greater than those in aboveground vegetation and dead roots among three types of grassland, therefore, we initially considered that living roots carbon density may be a sensitive indicator of grassland degradation.

    Ecological land has an important ecosystem service function, which plays a special role in maintaining ecological balance, ensuring land ecological security and coping regulation climate change. Based on the researches on ecological land from scholars, the paper defined the concept of ecological land from the perspective of ecosystem service function. According to the degree of hemeroby, the classification system of the ecological land was constructed. Meanwhile, the gap between the ecological land classification and land use classification was connected. The ecosystem services value of the ecological lands all over China was evaluated and its variation characteristics were analyzed. The results shows that: 1) Ecological land in a broad sense refers to land types which can supply, regulate, support ecosystem services, and play an important role in maintaining regional ecological balance and regulating global climate. 2) Based on the degree of hemeroby, the ecological land was divided into three level-one categories (non-interference ecological land, semi-interference ecological land and full disturbance ecological land), five level-two categories and 31 level-three categories. 3) In 2012, the ecosystem services value of the ecological land in China was 28 048 380 million yuan, and the spatial pattern was “the highest in the west, lower in the middle, and the lowest in the east”. The national ecological services value from 2009 to 2012 showed a downward trend. There was great spatial variation of the change that increase appeared in the central region and decrease appeared in the east and the west. During 2009-2012, all kinds of ecosystem services functions of ecological land were damaged and were declined year by year, suggesting that the ecosystem stability is low.

    Knowing the ecosystem pattern of nature reserves is of great significance to the understanding of the status of the ecological environment, the valuation of the protection effect, and the proposal of protective measures. In this paper, the transition trend of ecosystem pattern of nature reserves in Shanxi during 2000-2010 was analyzed with ecosystem transfer matrix and the Positive and Negative Transformation Index (PNTI) model, and the stability of ecosystem was analyzed with Shannon-Wiener diversity index and Net Primary Productivity (NPP) grading standard. The results showed that: 1) Forest ecosystem was the main ecosystem in the nature reserves in Shanxi, followed by grassland ecosystem and farmland ecosystem. From 2000 to 2010, the area of forest ecosystem increased, while the area of grassland ecosystem and farmland ecosystem decreased. 2) During the ten years, the grassland ecosystem had the largest area that transformed into forest ecosystem, which was 1 117.21 km2. It was the result of the natural forest protection project, Taihang Mountain greening project and plain greening project in Shanxi. In addition, 49.1 km2 farmland ecosystem transformed into forest ecosystem, which indicated that the vegetation was restored and the ecological environment was improved during the ten years. However, due to human disturbance, 466.72 km2 forest ecosystem degenerated into grassland, 3.63 km2 forest ecosystem and 5.92 km2 grassland ecosystem transformed into farmland ecosystem, and 4.18 km2 grassland ecosystem became construction land, which indicated that the management and rehabilitation of relevant nature reserves need to be strengthened. 3) The positive conversion rate of nature reserves was higher than the reverse conversion rate, and the ecological system pattern was developing in a favorable direction. The net conversion rate of the grassland meadow reserves, forest ecosystem reserves and wild plant reserves was 29.47%, 8% and 4.04%-7.32%, respectively. However, the net conversion rate of wildlife reserves was less than 1.1%, and the protective effect in wildlife reserves was weak. 4) The diversity index of nature reserves showed an increasing trend, and the stability of ecosystems enhanced. The total amount of NPP in the nature reserves increased from 2.51×107 g C to 2.59×107 g C. In general, the vegetation growth status of the nature reserves improved during the ten years. The average NPP of nature reserves was between 50-100 g C·m-2·a-1, belonging to the third-class vegetation NPP according to the NPP classification standard of China, which indicated that the ecosystem restoration stability of the nature reserves was strong. However, the NPP of the wildlife reserves, the wild plant reserves and the grassland meadow reserves decreased, and the stability of restoration in these areas became weak. In summary, the ecosystem structure of the nature reserves in Shanxi Province was developing in a favorable direction, the impedance stability and the restoration stability of the ecosystem were increasing, and the growth of vegetation was improved. The protection of forest ecosystem reserves was the most prominent, while the ecosystem stability of other reserves was weak, especially wildlife reserves, such as Lingqiu Black Stork Nature Reserve and Zezhou Monkey Nature Reserve, where there exited degradation phenomenon of forest and grassland. The management and reparation of wildlife reserves need to be strenghened.

    The decoupling relationship between construction land expansion and economic growth and its heterogeneity during 2000-2013 in the Yangtze Economic Belt (YEB) are analyzed at the prefecture-level administrative units based on GIS platform, Exploratory Spatial Data Analysis (ESDA) method and decoupling model. The results indicate that: 1) In recent 15 years, the construction land expansion and the economic growth in the YEB had distinctive stages and regional characteristics. Hot spot analysis shows that the hot spots of construction land growth were diffusive and cold spots of construction land growth gradually shrank. However, the evolution pattern of hot spots and cold spots of economic growth was not in step with the evolution pattern of construction land. 2) During 2000-2013, the coupling relationship between construction land expansion and economic growth in the YEB experienced from the processes of “negative decoupling and weak decoupling” to “weak decoupling” and “weak decoupling and coupling”. According to the calculation, the cities with “negative decoupling” accounted for 12.15% of all cites in the Yangtze River Delta during 2010-2013, decreasing 17.76% compared to the stage from 2000 to 2005. Meanwhile, the cities with “weak decoupling” and “strong decoupling” account for 65.42% of all cites in the Yangtze River Delta during 2010-2013, rising 11.22% compared to the stage from 2000 to 2005. On the whole, the decoupling degree between construction land expansion and economic growth in the YEB improved in recent 15 years. 3) Spatial heterogeneity analysis of decoupling degree indicates that the decoupling relationship between urban expansion and economic growth in the YEB presented weak spatial autocorrelation in all stages. Generally, the decoupling degree of city clusters in the Yangtze River Delta was gradually increasing, better than the decoupling degree of city clusters along the middle reaches of the Yangtze River and city clusters of Chengdu-Chongqing and Yunnan-Guizhou. The evolution mechanism of decoupling degree was closely connected with urban industrial structure, land use efficiency and land use mode.

    Shanxi Province, as a national base of energy resources and heavy chemical industry, its cities were confronted with dual pressure from transformation and development under the “new normal” background. By constructing the evaluation index system, the spatial and temporal patterns of the coordination relation between average annual growth rate of urban quality and urban scale of 11 prefecture-level cities in Shanxi Province were studied with the entropy method and coordination model. The result showed that: 1) The variation coefficient of urban scale was big, while the variation coefficient of urban quality was small; the spatial and temporal variations of urban quality, urban scale and comprehensive development level of prefecture-level cities were obvious and presented a “W” pattern from north to south. 2) There was an ambiguous relationship between the average annual growth rate of urban quality and the average annual growth rate of urban scale during the periods of 2005-2010 and 2010-2014, and there were two kinds of phenomena that the growth rate of urban quality was lower than the growth rate of urban scale and that the growth rate of urban quality was higher than the growth rate of urban scale. 3) The coordination relationship between the development of urban quality and urban scale presented obvious spatial variation, which resulted in different dominant styles of urban development in different periods. Therefore, urban development should be performed according to local conditions.

    A systematic revelation of the spatial features of growth in regional farming, forestry, animal husbandry and fishery from the perspective of industrial structure is conducive to the formulation of scientific agricultural development strategy. Based on the Esteban-Marquillas model, the study divides the agricultural growth into the weights of share, industrial structure, net competition and resource allocation. With the ESDA approach, the study carries out a systematic analysis on the spatial features of the growth in farming, forestry, animal husbandry and fishery at county level in Beijing-Tianjin-Hebei region from 2000 to 2014. The results are as follows: 1) From 2000 to 2014, the farming, forestry, animal husbandry and fishery in Beijing-Tianjin-Hebei region showed a growing trend with farming and animal husbandry being the major growing industries. 2) The agricultural growth at county level in Beijing-Tianjin-Hebei region shows obvious agglomerations, and the order of agglomeration degree in different industries from high to low is fishery, animal husbandry, forestry and farming. In terms of the four kinds of weights, the weights of share and industrial structure have the strongest agglomeration effect, and their agglomeration effect in different industries from high to low is fishery, animal husbandry, forestry and farming. The weights of net competition and resource allocation have agglomeration effects only in farming and animal husbandry, and their agglomeration effects in framing are the strongest. The high-high (or low-low) agglomerations of the four weights have low overlap, that is to say, the industrial pattern at county level in Beijing-Tianjin-Heibe need to be optimized. 3) The counties of Type Ⅰ (competitive advantages and high level of specialization) and Type Ⅳ (competitive disadvantages and low level of specialization) which have relatively reasonable agricultural resource allocation account for less than 50% (except for fishery). This shows that the comparative advantages of agricultural resource allocation at county level are not obvious and it lacks of coordination and division of responsibilities among counties. For the purpose of coordinated development of agriculture, a top-level design is needed to strengthen economic exchanges and industrial cooperation among counties. It is suggested to develop and implement differentiated agricultural development strategy and guide the flow of resources in case of excessive competition, and resource allocation efficiency should be improved to accelerate the agricultural structure and layout optimization.

    China’s coastal areas are the regions with the most prominent contradiction between supply and demand of land resources, where the oversize planning and expansion of economic zones have exacerbated the urban land issues. In this paper, economic zones were divided into three types according to the location relations between sixteen coastal economic zones and cities, which are away from city, at the edge of a city and inside a city. The spatial characteristics of the expansion of these three types of economic zones and the economic characteristics of the economic zones were studied. The research indicated that the expansion of the economic zones was related to the stage of economic growth and the peaks appeared at the early stage and the “second-time undertaking” stage. After 25 years of development, the largest expansion of the economic zone was less than 60 km2 in the current environment of economic development and land policy. In addition, the directions and forms of the expansion of different types are different. The economic zones away from cities expanded in multiple directions and along the traffic lines. The economic zones inside a city expanded inward or expanded outward in a narrow fan-shaped area, while the economic zones at the edge of a city could expand in areas from a wide fan-shaped to a semicircle. The expansion of the zones far away from city needs more investment, however, there are more room for economic development and higher economic output. Therefore, the scale and speed of expansion of the economic zones need to be planned properly in light of the local capital strength, the location and stage of the development of the zones.

    In this paper, we collected Gravity Recovery and Climate Experiment (GRACE) Tellus products data, GLDAS-Noah surface evapotranspiration data and ground observation rainfall data from 2003 to 2015 in China. The trends of water storage, rainfall and evapotranspiration and the correlations between them were analyzed with Theil-Sen Median trend analysis and Mann-Kendall test. Furthermore, empirical orthogonal function (EOF) decomposition was used to analyze the temporal and spatial distribution characteristics of total water storage in China. The results show that: 1) The annual variation of water reserves in China became more severe after 2006, and the characteristics of abnormal water storage periods can be characterized by precipitation and evapotranspiration. 2) From 2003 to 2015, the changes of water storage, rainfall and evapotranspiration had significant spatial variations. 3) In the past 13 years, climatic factors could explain more than 50% variation of water storage change in almost 18.6% of total area of China, mainly distributing in the Northeast China, the southeast coast area, the Sichuan Basin, the Qinghai Plateau and the northwest of Xinjiang. 4) The principal component information of GRACE water storage decomposed by EOF can characterize the temporal and spatial characteristics of the global and local water storage in China in the study period.

    The relationship between the water resources and urbanization is a hot spot in water science research. There is a complex intertwined relationship between water resources and urbanization. This paper selects a typical city in arid region, Zhangye City, as the research subject and takes the strictest water resources management system as constraint condition to analyze the influence of the most significant management system of the water resources on the process of urbanization. Based on the constraint on water resources, it brings in water-saving quantity and grey water footprint to improve the double-factor method for calculating water resources carrying capacity based on water quantity and water quality. A model for calculating the threshold of the urbanization level with the constraint of “Three Red Lines” on water resources management is established. Meanwhile, the paper predicates the urbanization level thresholds of Zhangye City in 2020 and 2030 via scenario simulation and analyzes the historical data of urban development, water resources and water utilization in Zhangye City. The results show as follows. Firstly, the available water resources in Zhangye City is 23.02×108 m3 by 2030 in total under the red lines of water resources development and utilization, which is basically the same as the current situation. In current situation of water resources utilization, the water carrying capacity is difficult to support the water demand in the process of urbanization and economic growth. Secondly, when strictly following the red line control of the water quota standard, the shortage of water carrying capacity in Zhangye City is expected to be alleviated, and the water quantity carrying capacity can provide 331.91×104 urban residents with living water by 2030. The increase in water carrying capacity is mainly due to the water saving in the agricultural sector. Thirdly, with the red line on water resources pollution, the upper limit of the water quality carrying capacity in Zhangye City is 62.47×104 people by 2030, which is only 78% of the planned urban population. The carrying capacity of water quality becomes a strong constraint during the process of urbanization and the ammonia emissions in urban areas are the main factors. Lastly, with the constraint of “Three Red Lines” on water resources management, the upper limit of urbanization level in Zhangye City is 48.05% by 2030. In the future development, Zhangye City should put emphasis on strengthening the agricultural saving and sewage treatment to improve the carrying capacity of the water quantity and water quality.

    Livelihood diversification of farm household has become a highlight phenomenon of rural social economy. There are different explanations on the mechanism of farmer’s livelihood diversification on the utilization of cultivated land. The influence mechanism and relationship among farmer’s livelihood diversification, cultivated land use changes and ecological environ-ment effects have become new entries for understanding man-earth relationship. In this paper, Yanchi County was taken as the study area, 222 farm households were surveyed to get the primary data. Under the framework of DFID’s sustainable livelihoods research, farm households’ livelihood capital was analyzed, and the diversity of livelihood was expressed with Shannon-Wiener index. Linear regression was used to analyze the driving factors of the livelihood diversification of farm households, and one-way AVOVA was applied to analyze the differences of farm households’ livelihood capital. Then, the effects of farm households’ livelihood on the utilization of cultivated land were analyzed. The main conclusions suggest that: 1) The proportion of non-farm income of farm household is between 0 to 96.6%. There are 78 part-time farming households and 41 non-farming households, accounting for 58% of the total surveyed farm households. 2) Human capital and natural capital are the two main factors leading to the livelihood diversification of farm households. The farm households with more labors and less per capita cultivated land or grassland have higher proportion of non-farm income. 3) High opportunity cost of farming labor promotes off-farm activities, and the households with higher opportunity cost have higher proportion of non-farm income. 4) There are significant differences among different types of farm household in the utilization of cultivated land. With the increase of livelihood diversification, the labor and land input decrease. The efficiency of cultivated land use of part-time farming households is the highest, and that of non-farming households is the lowest. Agro-pastoral interlaced ecological fragile region faces the challenges of ecosystem conservation, agricultural production and poverty alleviation. This paper argues that policymakers need to fully consider the changes of livelihood of local farmers, strengthen the guidance on off-farm employment, encourage cultivated land transferring, and promote the livelihood diversification of farm household to achieve win-win situation of social development, economic growth and ecosystem conservation.

    In order to illustrate the distribution pattern of soil organic carbon density (SOCD) and its main influencing factors in small karst watershed, this paper quantitatively analyzed the spatial heterogeneity and distribution characteristics of SOCD using 2 755 thoroughly investigated soil profiles consisting of 23 536 soil samples with geo-statistical analysis, and analyzed the major influencing factors of SOCD with canonical analysis. The result showed that the SOCD decreases gradually with soil depth’s increasing in the Houzhai Basin; in particular, the maximum value is 12.47 kg/m2 and the minimum value is 0.11 kg/m2. The average SOCD at 100 cm depth is 12.11 kg/m2, which is higher than the value at national level. An optimal fitting model for the SOCD in this basin is Gaussian model, showing a moderate spatial correlation. The Kriging interpolation suggested that the soil carbon density is higher in the east region, while lower in the south region, showing an ascending trend from the middle to the surrounding area. In the Houzhai Basin, the SOCD at the depth of 100 cm differs in soil with different vegetation types, different soil utilization types and different soil types. The soil thickness is positively correlated with organic carbon content, and gravel content, slope direction, slope, soil bulk density and the rock exposed rate are negatively correlated with organic carbon density. Soil thickness, rock coverage and gravel content are the principal influencing factors of SOCD in the Houzhai Basin, among which soil thickness has the greatest impact.

    Cropland intensification is a state of cultivated land development made by human beings, which is closely related to all aspects of agricultural production and agro-ecological environment. It also plays an important role in food security, ecological security and sustainable development of economy and society. It is thus of theoretical and realistic implication to study the cropland intensification. This article reviewed the latest progress of cropland intensification studies from four aspects of intensification on connotations, description indices, spatio-temporal pattern, drives and environmental benefit assessment. Based on the progress and deficiencies of existing research, the article puts forward new research priorities and directions, aiming at providing a scientific basis for further deep research on cropland intensification. Current research shows that there are several characteristics of cropland intensification. Firstly, the connotations of intensification are rich as different scientists provide different definitions, involving both socio-economic and geographical aspects. But there is a lack of widely-recognized definition of cropland intensification which integrates natural and social properties. Secondly, there are various indicators which describe different characteristics of crop intensification; however, there is a need to select unique or multiple indicators according to the aims of the study and the characteristics of regions. Thirdly, there is a variety of methods to study pattern and changes of cropland intensification, such as statistical methods and spatial analysis technologies. Both of these methods have advantages and disadvantages. The fusion of the two methods is a very important direction in the future. Fourthly, the influencing factors of cultivated land intensification are dynamic and complex, and there is no leading factor because of the scale effect. Fifthly, cropland intensification has multiple functions and effects. At present, studies focus more on the grain output than on the ecological environment effect. Future research needs to pay more attention to the combines of socio-economic science and natural science and strengthen the research paradigm of intensification, methods of spatio-temporal pattern detection and assessment of comprehensive effect to achieve “sustainable intensification”.
