摘要
为了对锗煤露天矿排土场高陡边坡削坡 20°后的生态修复效果进行评价,采用Sentinel-2 遥感数据,运用主成分分析法构建了削坡区域RSEI遥感生态指数,研究分析了生态环境质量的演替规律.结果表明:高陡边坡削坡后可实现保水保墒,减少水分蒸发等作用,其生态环境质量明显改善,3～5 年基本可实现免维护状态.
Abstract
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.
