Ecological restoration evaluation under the background of 20°slope cutting in the germanium coal open-pit mine dump of Wumei Company
In order to evaluate the ecological restoration effect of the high and steep slope of the germanium coal open-pit mine dump after slope cutting by 20°,the article adopts Sentinel-2 remote sensing data,uses the principal component analysis to construct RSEI remote sensing ecological index in the cutting area,studies and analyzes the rule of ecological environmental quality.The results show that the high and steep slope can conserve water and reduce water evaporation after slope cutting,and the ecological environment quality is obviously improved,and maintenance free state can be realized basically in 3-5 years.
