    The emergence and development of the e-society affect the relationship between man and land. Smart technology, as one of the main driving forces and an important support for the rise of the e-society, is changing the mode of protection, development and governance of territorial space. It also puts forward new requirements for the compilation method of territorial spatial planning. At present, the application of smart technology in territorial spatial planning has been explored, and there are many practices at the technical level, but there is a lack of holistic thinking on the application of smart technology in territorial spatial planning. Based on the core concept of "ecological civilization" and "people-oriented", and on the basis of combing the traditional planning and the current application of smart technology, this paper systematically constructs a framework of the whole process of smart technology-assisted territorial spatial planning from four aspects: smart perception and collection, smart analysis and processing, smart evaluation and smart decision-making, so as to adapt to the current territorial spatial planning. To meet the new requirements, it is more reasonable, scientific and wise to assist in territorial spatial planning.

    Shenyang's practice and optimizing exploration of "Three Control Lines" in territorial spatial planning

    Before the institutional reform of the State Council, the "Three Control Lines" of ecological protection red line, permanent basic farmland and urban development boundary were delineated by different ministries, which resulted in insufficient coordination and overlapping results, and difficulties in implementing management. After the institutional reform of the State Council, the Ministry of Natural Resources is responsible for establishing a spatial planning system. It requires that the three control lines be delineated from top to bottom on the basis of the evaluation of the urban capacity of resources and environment and the suitability of territorial spatial development. This paper summarizes the manifestations and causes of contradictions and conflicts in the delimitation of the three control lines in Shenyang as a pilot city, constructs relationships between the three control lines and the three spaces of ecology, agriculture and cities, establishes the management system and adjustment rules, and explains the adjustment and optimization practices within the scope of the city. The study found that it is difficult to distinguish the functions of the three control lines overlapped in space, mainly because permanent basic farmland undertakes the mission of restricting urban spatial spread, and the index can not be adjusted across administrative regions, which results in some permanent basic farmland having to be arranged in cities; different definitions leading to some urban parks are classified as ecological protection redline; some cultivated land in ecological protection redline was previously classified as permanent basic farmland. The paper puts forward the optimization proposals of three control lines under the background of territorial spatial planning: First, we highlight the characteristics of both the policy line and the technical line, and delimit them from top down and bottom up; second, the country needs to carry on the innovation to the basic farmland adjustment policy and system; third, we will establish a hierarchical management mechanism to properly reserve the flexibility of local administrative power.

    Classification, scope and the impact of human activities of ecological space in Tibet Autonomous Region

    The delimitation of ecological space is an important basis for the scientific management of territorial space and the maintenance of regional ecological security. Since the beginning of the 21st century, China has undergone an unprecedented rapid urbanization process, and the territorial spatial pattern has changed dramatically. However, during this period, a series of disorderly processes of territorial spatial development have resulted in the squeezing of ecological space and many severe regional ecological problems, such as land desertification, biodiversity reduction, ecosystem degradation, which restricts the realization of the goal of sustainable development. The definition of ecological space is mainly put forward by domestic scholars in recent years, and the corresponding concepts in other countries are ecoregion, ecological land space, and green space etc., and the classification system of ecological space is also not unified. Taking the Tibet Autonomous Region (TAR) as an example, we explored the classification system, spatial distribution, attribution of the patches, and human activities intensity of ecological space on provincial scale in the study. The results are as follows. (1) The classification system of ecological space can be composed by 3 hierarchal systems. According to various ecosystems and dominant functions, there are 4 land categories in the primary-class system, 13 sub-categories of land in the second-class system and 29 sub-categories of land in the third-class system. And according to the ecological governance intensity from the strictest regulation to the relatively relaxed regulation, ecological space can be divided into I-level, II-level and III-level areas. (2) Guided by the current spatial planning and governance system, the link between the classification system of ecological space and the existing land classification system such as the land cover and land use classification, ecosystem type was built; the spatial distribution of ecological space, and the attribution of the patches within the space was identified. Besides, the key ecosystem services functional area and the main ecological frangible area were also identified and included into the ecological space. The existing land classification system, the ecosystem services functional area and frangible ecosystem, and the various space can be integrated in GIS environment. The total ecological space of TAR is about 1054500 km2, accounting for 87.7% of the total area. (3) Finally, human activities within the ecological space in Tibet were simulated in order to control the human activities intensity of ecological space and to maintain the ecological security.

    Establishment and application of one map of current situation of territorial spatial planning according to the foundations of natural resources: Taking Qingdao city as an example

    The construction of the territorial spatial planning system has been fully carried out. The clear and detailed status map and data are an important basis for understanding the natural resources, and also an important support for the preparation of territorial spatial planning. However, the current land classification standards, data accuracy and application targets of the current territorial spatial data are not uniform. Based on remote sensing images, geographic conditions and Internet POI data, this paper studies one map of land and space status, synthesizes existing land classification standards and data accuracy, and constructs one map of territorial spatial planning status of Qingdao city. On this basis, the application direction of one map of territorial spatial planning is discussed, including the preliminary delimitation of "Production-Living-Ecological Space" in Qingdao city. The suitability of urban construction, the importance of ecological service function and the suitability of agricultural production were analyzed. The construction of one map of the status of territorial spatial planning plays an important role in defining the resource utilization cap and the environmental quality bottom line, standardizing the territorial spatial planning data, and supporting the preparation and management of territorial spatial planning.
