Study On Boundary Demarcation Methods Of Protected Areas Basic On The Assessment Of Ecosystem Integrity

The "Guiding Opinions on Establishing a System of Nature Reserves with National Parks as the Main Part"(hereinafter referred to as the "Guiding Opinions")proproses that China should be established a national park in China are put forward as the main body of the natural protected area system,clear the must be integrated on the same physical geography unit within adjacent,connected to all kinds of natural protected area,optimize the border,to protect the integrity of the natural ecological system.The planning of protected natural areas is an important part of landscape planning practice.The boundary demarcation is the primary link in the construction of protected natural areas,which is used to restrict different land use forms and human activities inside and outside the boundary,and directly affects the smooth development of nature conservation actions.This paper attempts to discuss the method and theory of boundary demarcation of natural protected areas,so as to provide ideas and references for the research of planning and construction of various protected areas in China.In the past,domestic scholars have made many attempts and practices on the boundary demarcation of various types of natural protected areas.Most of the applied methods are based on the morphological element method from the perspective of ecological elements,which cannot meet the requirements of the reformed natural protected areas system for the overall protection of natural ecosystem.A few scholars have applied the regional assessment method to guide the boundary demarcation of protected natural areas from the perspective of ecosystem internal functions and ecosystem services,but such methods are still in the development stage.Evaluation method in this paper,we study along the area of ideas,for ever and clear demarcation method adapt to changing times and policy requirements,the application of the theory of landscape ecology,based on the integrity of the ecosystem of natural protected area boundary delimitation methods: first of all,according to the literature analysis to screen and optimize the ecosystem integrity evaluation index,based on the ecological system the structure,function,composition of index system,using the analytic hierarchy process(AHP)construct the ecological system integrity evaluation system;Then,the areas with the highest integrity level in the evaluation results were selected as the source areas,and the minimum cumulative resistance model was constructed to identify the important ecological corridors.Finally,the important ecological areas with higher integrity level and the identified important ecological corridors were superimposed,and the outer boundary of the protected areas was obtained by checking and modifying the natural boundary.Finally,within the established outer boundary,the areas with the highest ecological integrity level are selected,the ecological corridors are connected,the boundary of the core protection area is delimited,and the distribution of important resources is used for discussion and correction.According to the boundary demarcation model constructed in this paper,the boundary demarcation of natural protected areas in Wugong Mountain of Jiangxi Province was practiced,which verified the feasibility of the demarcation model presented in this paper,and the shortcomings of demarcation method and data acquisition were summarized,providing ideas and references for the related research on natural protected areas.
