以黄河沿岸山西省临猗县为例,对其生态环境质量时空变化及其成因进行分析,旨在为生态保护和可持续发展提供科学依据.研究选取1990-2020 年Landsat影像,提取湿度(WET)、绿度(NDVI)、干度(NDSI)和热度(LST)4 项指标,计算遥感生态指数(RSEI),对临猗县生态环境质量进行评价,并用地理探测器进行因子分析.结果表明:研究区生态环境质量1990-2000 年轻度恶化,2000-2010 年轻度改善,2010-2020 年轻度恶化,总体有所恶化.影响因子在1990 年和2000 年为湿度>热度>干度>绿度,2010 年为热度>湿度>干度>绿度,2020 年为湿度>干度>绿度>热度.
Taking the example of Linyi county in Shanxi province along the Yellow River,this paper analyzes the temporal and spatial changes of eco-environmental quality and its causes,aiming at providing scientific basis for ecological protection and sustainable de-velopment.This study selected Landsat images from 1990 to 2020,extracted four indicators of Wetness(WET),greenness(NDVI),dryness(NDSI)and heat(LST),calculated the remote sensing ecological index(RSEI),and carried out evaluation on the ecologi-cal environment quality in Linyi county,and used geographical detector for factor analysis.The results show that the ecological environ-mental quality deteriorated slightly from 1990 to 2000,improved mildly from 2000 to 2010,and worsened gently from 2010 to 2020.The influencing factors were wetness>heat>dryness>greenness from 1990 to 2000,heat>wetness>dryness>greenness in 2010 and wetness>dryness>greenness>heat in 2020.
