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.
