Abstract:

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.
