基于生态系统服务的生态保护修复研究
Research on ecological protection and restoration based on ecosystem services:taking the Qinba Biodiversity Ecological Functional Zone as an example
摘要
Abstract
China attaches great importance to ecological protection work.With the implementation of national ecological restoration projects,there is little research on the impact and thinking on the theory and practice of ecological restoration implementation.The Qinba Biodiversity Ecological Functional Zone is one of the 25 national key ecological functional zones in the National Main Functional Zone Plan,and also one of the 63 important ecological functional zones in the National Ecological Functional Zoning(Revised Edition).It is an important area for biodiversity protection and water conservation in the Qinling Daba Mountains,with important functions for biodiversity maintenance and water conservation.This article takes Zhen'an County of Shaanxi Province,the Qinba Biodiversity Ecological Functional Zone,as an example.Using the millennium ecosystem assessment method and based on the equivalent table of ecosystem service value per unit area,combined with the actual situation of Zhen'an County,the application research of ecosystem service value evaluation in regional ecological protection and restoration is explored.The research results indicate that:(1)The secondary ecological function ecological service value of various land types in Zhen'an County is gradually decreasing.The value of six ecological services,including food production,raw material production,water supply,gas regulation,soil conservation,and nutrient cycling,has all experienced varying degrees of decline.The highest absolute change rate in the value of ecological environmental services between 2011 and 2020 was the soil conservation function,which was 60.05%.(2)The ecological environment protection and restoration in Zhen'an County need to focus on soil conservation function,hydrological regulation ecosystem function,and water resource supply function.(3)This article proposes an ecological protection and restoration engineering plan with the direction and goal of comprehensive renovation of agricultural space,comprehensive renovation of urban space,and ecological restoration of ecological space.(4)Based on the results of delineating the ecological red line in Zhen'an County,this article has determined the overall layout of key restoration areas,including the ecological protection red line range,natural reserves,water source protection areas,and mining restoration areas.Through ecological restoration,a"three green hearts,two clear water corridors,and three river basin ecological security pattern"has been formed.关键词
