北京市密云区矿山环境治理遥感调查与分析
Remote sensing investigation and analysis of mining environmental governance in Miyun district of Beijing
摘要
Abstract
In order to understand the current status of mining environment restoration and governance in a quick,efficient,and real-time manner,remote sensing investigation was used in Miyun District,Beijing in 2022.The survey results show that in 2022,a total of 256 mining polygons were interpreted.240 mining polygons with an area of 863.35 hectares have been treated or naturally restored.There are 16 untreated mining polygons with an area of 200.44 hectares.A total of 6 types of land uses exist for the mines with the following descending order of land area occupation:stope,waste dump,tailing pond,waste rock heap,mining buildings,and exposed rocks.Among them,the treatment rates of tailing pond and exposed rock are the highest,both at 100%;The stope treatment rate is the lowest,at 66.21%;Compared to 2021,there were no new terrain and landscape destruction polygons in 2022,and one newly completed governance spot with an area of 11.87 hectares was added;There are still some untreated mines mainly of the mining area type with a map area of 180.62 hectares,accounting for 90%of the total untreated map area in Miyun District.This untreated area poses a significant impact on the surrounding environment.关键词
