Natural protected area system integration and boundary demarcation method

Abstract

The invention discloses a natural protected area system integration and boundary demarcation method. The method comprises the following steps: (1) determining a protected area integration and mergingprinciple; (2) for a region to be integrated and merged, constructing an ecological suitability, cultivated land suitability and construction suitability evaluation index system, and performing indexstandardization processing and weight assignment; calculating a suitability comprehensive index of each type of land, constructing a conflict pattern spot suitability land type discrimination matrix for qualitative evaluation, and drawing a suitability land type spatial layout map; (3) selecting evaluation reference elements for protected area boundary optimization; (4) evaluating resource background characteristics and carrying out primary aggregation optimization; (5) extracting an existing element and resource base aggregation result according to the protected area heritage resource characteristics to carry out intersection optimization; and (6) linking and coordinating the result with a construction management condition, and delimiting a new protected area boundary. According to the method, the problem of conflict patches of the natural reserve can be solved, and a scientific, reasonable, clear and definite natural reserve boundary is formed.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and resource comprehensive utilization, and in particular relates to a method for system integration and boundary delineation of nature reserves. Background technique [0002] Protected areas include nature reserves, scenic spots, national forest parks in natural forests, and world natural and cultural heritage sites. By the end of 2017, China had more than 10,000 nature reserves, accounting for 18% of China's territory. [0003] However, my country is facing serious challenges to the environment and ecosystem brought about by severe population pressure and rapid economic development. Moreover, the loss of biodiversity and cultural heritage in protected areas continues due to lack of funds, chaotic management, non-compliance with or lax enforcement of laws, and administrative interference. In particular, the current chaotic hydropower development, tourism development and mineral...

Problems solved by technology

[0007] Domestic research at the present stage is mainly limited to the monitoring of protected areas and the evaluation of protection effects. However, there are a series of problems in the current management of protected areas in my country: including externalities caused by administrative divisions, division of departments, protection Due to the islanding and fragmentation of protected areas caused by different starting points and logic, and the problem of overlapping and chaotic management, it is urgent to design a method for the integration and boundary delineation of the natural protected area system to provide technical support for the construction of the natural protected area system.
