    With the development of urbanization, the vulnerability of cities is increasing. In recent years, frequent production accidents highlight the limitations of traditional risk management paradigm. Source prevention and control, multiple actors' participation, and data-driving are important issues in the current production safety risk management. How to link the concept of territorial spatial safety with the demands of industry production safety is an important cornerstone to promote the sustainable development of economy and society. It is necessary to introduce holistic thinking to innovate the management normal form of industry production safety risks. The risk generating ring and territorial spatial ring (double ring conceptual model) under the mutual construction of "three living" spaces are the theoretical basis of risk management from the perspective of multidimensional safety and spatio-temporal distribution. The model points out the overall idea of focusing on the source of risk and expanding the perspective, means and main body of risk prevention and control. It aims at mining the positive role of information technology in territorial dynamic monitoring and risk cognition accumulation, and then building a "flat" risk monitoring and evaluation framework to explore the needs and functions of the "brain" - information platform. Taking the chemical industry as an example, this paper focuses on the multiple actors' prevention and control paradigm and proposes a basic framework of production safety risk under the leadership of industrial parks, so as to provide reference for the formulation of risk prevention and control schemes for different industries.

    To satisfy the needs of territorial spatial planning system construction and response to public health emergencies, it is necessary to reform regulatory detailed planning indicators and management system. On the basis of in-depth analysis of the response and inadequacy of the existing control management to territorial space emergency safety and security, this study proposed the "prevention + emergency" regulatory planning management path and constructed the index implementation system. "Prevention" refers to the shaping of the spatial environment to improve urban resilience and enhance the city's ability to resist the risk of uncertainty. The main methods of "prevention" are: (1) Integrating the concept of healthy city into the index system of regulatory detailed planning. (2) Reducing the management scale of regulatory detailed planning units to form a spatial transmission system from the zone unit to the block unit. "Emergency" is to ensure the sustainability of the city's life system in the event of a public health emergency through control and regulation management, and to meet the need for epidemic prevention by guiding the compatibility of part of the land and the layout of emergency facilities, access and space through control and regulation.

    Thoughts on space planning system under the background of national territorial space security in the New Period
    ZHAO Yao, YE Qiang, TAN Chun-hua, HU Zan-ying, XIANG Hui

    At present, the mode of administration of territorial space is changing from the original "cluster" of space planning to a unified territorial spatial planning. The territorial space security, the bottom line of space development, has become the focus of heated discussions from all walks of life. Based on the system theory, this paper sorts out the territorial space and its planning system, and mainly analyzes what kind of territorial spatial planning can better guarantee the security of territorial space. Studies have shown that: (1) A sound legal system and a scientific system interface for territorial spatial planning are the key to ensuring the security of the territorial spatial planning. (2) The legislation for territorial spatial planning should be established with the law of territorial spatial planning as the basic law, and a clear structure and unified content legal system with laws, regulations and standard systems as the core should be formed to make the territorial spatial planning system structure reasonable. (3) In terms of system interface, we should establish a three-dimensional system with hardware interfaces and software interfaces as the main types and the entire life cycle of territorial spatial planning as the core. The system interface can realize the three-dimensional connection of "five levels, three types and four systems".

    Spatial allocation efficiency and control strategy of county land resources based on main functional areas of territorial space: A case study of Ganyu, Jiangsu province
    JIANG Hai, CHEN Lei

    In terms of the county area, widening the concept application of main functional areas and exploring the spatial allocation efficiency of land resources and its control strategies are of great significance to deepening China's territorial space governance system. This paper combs the theoretical relationship between main functional areas and land resources spatial allocation, the spatial allocation efficiency of land resources in main functional areas of Ganyu district, a typical county-level unit in Jiangsu province, was investigated with the C-D production function, and the differentiated control strategy was put forward. The result shows that the essence of main functional areas construction is "based on land", and land resources spatial allocation should follow the transformation degree of equal marginal net income based on the concept of functional zoning, which makes it possible to improve land efficiency and reduce the efficiency loss of spontaneous competitive advantage. A study of Ganyu district found that the excessive allocation of agricultural land to development land in different main functional areas has the pareto improvement space, which is rooted in the inelastic mechanism of the current land planning management to regulate the spatial land use index, resulting in the spatial mismatch in the actual landing. Therefore, the effective allocation of land resources in Ganyu should be based on the overall planning of main functions and the coordination of land space development pattern, including: optimizing development areas should renovate the spatial structure of land and transform the mode of economic and industrial development; key development areas will contribute to the industrialization of cities and towns and ensure the efficiency of land resources use in the region; restricted development areas focus on the safety of grain and economic products and innovate the management mode of agricultural production land; prohibited development areas draw the red line of ecological space in development zones and explore the layout and structure of agricultural and tourism ecological land.
