生态系统服务价值时空分异及驱动因子分析
Spatio-Temporal Differentiation and Driving Factors Analysis of Ecosystem Service Value
摘要
Abstract
Based on the land use data of the Changsha-Zhuzhou-Xiangtan ecological green heart area in the past 20 years,this paper applies GIS spatial analysis and geographical detectors to calculate the ecosystem service value(ESV)of each year,quantitatively explores the spatio-temporal distribution variation characteristics of the ecosystem service value in the ecological green heart area,and analyzes the main driving factors of ESV changes.The results show that:①Forestland constituted the dominant land-use type that affects the changes in the value of ecosystem services in the green heart area.②From 2000 to 2020,affected by policy-driven regulation measures,the total value of ecosystem services in the green heart area showed a fluctuating trend of first declining and then slowly growing.③The ESV in the ecological green heart area of Changsha-Zhuzhou-Xiangtan shows a spatial distribution feature of high regional value in the central,eastern and southern regions and relatively low value in the western and northern regions.Specifically,Shiyan Lake Forest Park,Jiulangshan Forest Park and Zhaoshan Forest Park are the areas with the highest value distribution,while the urban-rural fringe areas close to the main urban areas of the three cities of Changsha-Zhuzhou-Xiangtan are the areas with the lowest value distribution.④In-depth analysis by geographical detectors reveals that the spatial distribution differences of ESV in the green heart area are a comprehensive manifestation of the interwoven influence of three types of regional natural,economic and social factors,among which the contribution value of natural factors is the greatest.关键词
