    The urban system is faced with more uncertain risks and unknown disturbances in the coming future, which requires that the urban safety and disaster prevention planning should carry out adaptive adjustment in terms of target object, strategic positioning, technical means, planning concept, etc., so as to achieve regional security and stable development through flexible urban design. In this paper, we summarize and comment the theoretical development and practical exploration of resilient city. Combined with the construction of territorial planning system after "multi planning integration" in China, we reconsider the connotation characteristic, process structure, form content and public governance of resilient planning under the background of territorial governance. Then we put forward practice outlook of urban resilience and safety planning from four aspects, including deepening the theoretical construction and mechanism research of resilient city, changing the design thought and practice flow of planning, improving management and control transmission and scale governance in the practice, and focusing on the grassroots governance and public participation in resilience design. All the efforts are contributed to promote the modernization of urban public security governance construction in China.

    Public security events are the results of the interaction of 'Human-Space-Time' in a specific context. Public security spatial planning and the corresponding administration system are important approaches to deal with the public security events in the long term. Based on the framework of 'Human-Space-Time' interaction in the public security planning, this paper reviews the relevant research about 'prevention, early warning, emergency dispatching, and post-disaster recovery'. On this basis, the framework of content, technical methods and support system of public security spatial planning is constructed. First, the content system should be consistent to the multi-level spatial planning system and the national emergency response mechanism. It is necessary to implement special planning and comprehensive planning, focusing on the problems of the planning and management of space, facilities and emergence response in terms of natural disasters, accident disasters, public health events and social security events. In terms of the technical method system, it is necessary to build and improve the methodological and technical support system of space-time elements identification and analysis, space-time process simulation and early warning of public security events. Last, for the support system, it is necessary to improve the space-time accessibility of the public security facilities system and strengthen the public security oriented social governance, based on the new infrastructure construction such as the space-time big data management system.

    At present, China's territory spatial planning attempts from top to bottom to resolve or relieve the key issues from macro level as far as possible which has arisen since the reform and opening-up such as the ecological environment, resources restriction, the conflict of man-land relationship, multiple management and the authority of spatial plans. Although China's territory spatial planning system, organization framework and technical regulation have so far formed relatively reasonable "universality" norms, at the strategic level, the discussion of regional "individuality" issues in the context of national security is still lacking. Facing the needs of the country and the special situation of Western China, we should establish a cross- province and cross-basin territory spatial planning of this region based on national security strategies. To ensure national security, territory spatial planning of Western China at the strategic level should focus on the following: (1) In theory, based on the perspective of national security, we proposed to construct the cross-province and cross-basin territory spatial planning of Western China. (2) In practice, we recommend formulating the "territory spatial planning of Western China-ecological security" of specialized national territory spatial planning which takes ecological zone, nature reserve as the core in spatial scale. What's more, based on the border and support line, we should carry out "territory spatial planning of Western China-survival security" of specialized national territory spatial planning, or determine the detailed rules and regulations of national defense security in spatial planning. In addition, taking the urban system as the organizational context, we should set up "territory spatial planning of Western China-life security" of specialized national territory spatial planning which is relying on main transportation lines, or determine the detailed rules and regulations of the harmonious society construction in Western China. Besides, following the divisions of the Main Functional Areas, we should formulate "territory spatial planning of Western China-production security" of specialized national territory spatial planning which is focusing on the regional central city and urban agglomeration, or determine the high-quality economic development in the western region. We should also restructure the ecological space, survivable space, living space and production space. (3) In particular, we recommended strengthening the construction of border towns or villages, and establishing the "sanxian" (three lines) construction in the New Era, "the key construction belt around the Qinghai-Tibet Plateau" in the western region, which can meet the national security needs of limited globalization and achieve "dual circulation pattern" in the post-epidemic period. On the whole, the territory spatial planning of Western China should be different from that of the eastern and central regions. We should not impose uniformity on the implementation of the policies.

    In the process of rapid industrialization and urbanization, the interference effect of human activities on the structure and function of ecosystem has been increasingly intensified. Land ecological restoration has become an essential topic of ecological civilization construction and land spatial planning. Determining priority areas for ecological restoration based on holistic protection and systematic governance, is a critical method for the scientific and orderly promotion of land ecological restoration. Taking Changsha-Zhuzhou-Xiangtan Urban Agglomeration as an example, we used human footprint to evaluate the intensity of human disturbance to the ecosystem quantitatively. On this basis, through the minimum cumulative resistance model, circuit theory, and cyclic window search method, the ecological network was identified, and the key areas where human disturbance caused damage to its structure and function were determined as priority areas for ecological restoration. The research showed that: (1) The human disturbance in the urban agglomeration presented a core-edge decreasing circle distribution, and the west was higher than the east while the north was higher than the south. In the study area, low disturbance area, medium-low disturbance area, medium-high disturbance area, and high disturbance area accounted for 12.66%, 32.31%, 37.70%, and 17.33% of the urban agglomeration land, respectively. (2) The ecological network was identified, which contained 140 ecological source patches and 307 potential ecological corridors between them. The corridors were 3986.02 km long, primarily distributed along with the Xiangjiang River system or located in the low hilly area with good vegetation coverage. (3) The priority areas for ecological restoration were determined, including a total of 867.17 km2 for source restoration, 97.83 km for corridor restoration, and 40 points for pinch point restoration. From the perspective of Point-Line-Polygon, restoration strategies were proposed to eliminate or weaken human disturbance, which would help to provide spatial guidance for formulating and implementing of land ecological restoration in the New Era.

    With the transformation brought by the renewal and reform of territorial space planning, the improvement of the value of territorial ecological space, the construction of security pattern and the integrated development of multiple elements are becoming more and more important. The establishment of the national territory development planning system is the great ecological significance, and ecological priority is the core value of the formation of the national territory development planning system. Among them, the ecological restoration planning at the county level is an important part of the current national territory development planning. This study takes the land space of Weiyuan county, Sichuan as the research object, analyzes its serious problems of ecological resources destruction, ecosystem disruption, and low ecological efficiency in the background of industrialization and urbanization. It is pointed out that the construction of ecological security pattern is the goal orientation of national territory ecological restoration planning, and the evaluation index system of coupling degree is constructed by using the coupling method of eco-socioeconomic system. From the three aspects of the restoration of ecological elements, the optimization of ecological structure and the promotion of ecosystem value, combined with the typical ecological engineering technology, the ecological restoration security pattern composed of point, line and area is constructed, and the countermeasures of ecological management and restoration are proposed. The results show that: (1) The ecological restoration planning of counties has the characteristics of multi-level objectives, system complexity and diversity of approaches, and the response planning countermeasures can be put forward from the macro, meso and micro levels. (2) The coupling degree of eco-socioeconomic system in Weiyuan fluctuates between 0.457 and 0.497, and the ecosystem and socioeconomic system are now in an antagonistic period and have a development trend in the running-in period. (3) According to the calculation results of coupling degree, comprehensive efficacy and index influence degree, the overall pattern of ecological restoration of "multi-corridor and multi-point, two veins and two rings, one screen and two areas" can be constructed. The study puts forward the special planning methods and practical application of ecological restoration at the county scale, which can provide new ideas and methods for the current national territory spatial ecological restoration planning system of counties.
