The optimization of ecological service function and planning control of territorial space planning for ecological protection and restoration

Abstract

With the rapid advancement of industrialization and urbanization, the scale of cities has continued to expand, the crisis of resource shortages has appeared, and the pressure on the ecological environment has increased. Land is a natural substance that exists before humans, and it is also the first objective object that humans come into contact with after being separated from nature. When land is invested in human social production activities, it becomes a necessary and irreplaceable material condition for any social material production sector. The quality of the ecological environment in some cities continues to decline, and the ecological space is gradually compressed. This research mainly discusses the optimization of ecological service functions and planning control of land and space planning based on ecological protection and restoration. In the past, the selection of evaluation indicators for research mostly only started with some basic service functions of the ecosystem. Based on the basic service functions of the ecosystem, this paper takes into account the direct economic benefits of the ecosystem, and adds the evaluation of the importance of ecological support functions to evaluate the ecological service functions more comprehensively. From the perspective of man-land relationship and structuralism, this paper constructs an ecological space evaluation plan based on the perspective of ecosystem services. It constructs a reasonable index system and selects an appropriate scale, and sets the weight of each index for the three leading functions of supply and support service function, adjustment service function, and social service function. According to the principle of regional differences and the consistency of zoning indicators, the factors that play a leading role in various plans are integrated and selected. It transfers elements of different themes such as society, economy and ecological environment of land and space to the expression of land and space functions through indicators. This research discusses in detail the methods of using important control lines to control the main space and the design of relevant policies and regulations to solve the problems of overlapping control areas of land and space planning, mixed objects, and ambiguous powers. In order to ensure the feasibility of the downward transmission of the important control line control system, it provides reference policies, regulations and technical basis for the preparation and implementation of the entire territory and space planning. Finally, the red line area of the importance of ecological service function is delineated. The area of the red line area is 192.79km2, accounting for 20.38% of the study area. This study will provide reference for the planning of land and space.
