为研究北京王平煤矿生态修复成效,以1990—2021年Landsat遥感影像数据为基础,采用遥感生态指数(remotesensingecologyindex,RSEI)对北京王平煤矿区生态修复工程展开效果评估,并结合GM(1,1)模型对研究区生态环境质量进行动态监测、时空分析及预测研究,以期为矿山生态修复工程的管理提供参考。结果表明:1990—2021年,王平煤矿生态环境质量呈现出“先降低,后上升”的势态;1990—2001年研究区RSEI等级差与较差的区域集中在东北部与西南部,生态修复工程开展后,王平煤矿生态环境质量逐年得到改善,少量较差区域集中在东北部边界地区;对王平煤矿RSEI进行预测,预计2025年RSEI将达到0.826,研究区生态环境质量将达到“优”级,表明开展矿山生态修复工程效果较显著。

In order to clarify the ecological restoration effect of Beijing Wangping Coal Mine. Based on the remote sensingCoal Mine is improved year by year,and a small number of poor areas are concentrated in the border area of the northeast. Based on the prediction of RSEI in Wangping Coal Mine,it is expected that the RSEI will reach 0. 826 in 2025,and the ecological environment quality of the study area will reach the “excellent” level,indicating that the effect of the mine ecological restoration project is remarkable.
