Spatial Evolution of ecosystem service value:based on empirical analysis of 90 counties in Zhejiang Province
On the basis of quantitatively measuring the ecosystem service value(ESV)in Zhejiang Province,this study analyzes its spatial evolution trend and explores the realization path of ecosystem service value in various functional areas,aiming to provide theoretical support for the sustainable development of Zhejiang Province.This study employs methods such as the equivalent factor evaluation method and NDVI correction method.The results show that:(1)From 2005 to 2020,the construction effectiveness of the demonstration area for the transformation of the"Two Mountains"in Zhejiang Province was significant,with the total ESV value increasing from 2831.96 billion RMB to 2917.55 billion RMB;(2)The ecological regulation function and aesthetic landscape conditions in Zhejiang Province tend to be optimized,and the regulatory service value is the most important source of ecosystem service value in Zhejiang Province;(3)The ecosystem service value in Zhejiang Province shows a pattern of high values in the western Zhejiang region and low values in the northern and southeastern coastal areas,with spatial differences tending to balance out;(4)The dominant functional zoning results show that the dominant areas of raw material production,climate regulation,and soil conservation are widely distributed in Zhejiang Province,with great potential for the exploitation of ecosystem cultural service functions.With the gradual promotion of the"Two Mountains"transformation demonstration area in the future,the regional ecosystem service value in China is expected to further increase.It is necessary to implement the zoning control of ecological space under the guidance of territorial space,establish a dynamic monitoring and evaluation system and a differentiated ecological service value development strategy.
