2000-2023年黄河流域山西段生态环境质量时空变化及其驱动因素
Spatiotemporal changes and driving factors of ecological environment quality in the Shanxi section of the Yellow River Basin from 2000 to 2023
摘要
Abstract
Based on the Google Earth Engine(GEE)platform,this study coupled aerosol optical depth with the remote sensing ecological index to construct a modified remote sensing ecological index(MRSEI)for comprehen-sively evaluating the spatiotemporal variation and driving mechanisms of ecological environment quality in the Shanxi section of the Yellow River Basin,China,from 2000 to 2023.The results show that:(1)MRSEI substan-tially improved the accuracy of ecological environment quality assessment,with stronger texture features and bet-ter detail representation.(2)From 2000 to 2023,ecological environment quality in the study area improved over-all.Most areas were classified as general or good,with only a small proportion at poor levels.Spatially,MRSEI indicated a low-high gradient from northwest to southeast.The western part of Lüliang City exhibited the poorest ecological quality,with unfavorable conditions also observed in Datong City,Shuozhou City,and Xinzhou City.In contrast,Changzhi City,eastern Linfen City,parts of Jincheng City,and eastern Yuncheng City showed the best conditions.(3)Land use type exerted the greatest influence on ecological environment quality,followed by annual precipitation,slope,and elevation.Interactions among factors were significantly enhanced,particularly be-tween land use type and other variables.This study provides a scientific basis for ecological environment protec-tion and sustainable development in the Shanxi section of the Yellow River Basin.关键词
