Spatial-temporal Evolution and Cause Analysis of Eco-environmental Quality along the Yellow River in Linyi County
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.
