摘 要:为更加快速、高效、实时了解矿山环境治理恢复现状,利用遥感技术手段对北京市密云区2022年矿山环境恢复治理情况进行调查。结果表明:2022年共解译矿山图斑256个,其中已治理或自然恢复图斑240个,面积863.35 hm^(2);现存未治理图斑16个、面积200.44 hm^(2)。解译图斑矿山用地类型共6类,占地面积从大到小依次为采场、排土场、尾矿库、废石堆、矿山建筑、裸露岩石。尾矿库与裸露岩石治理率最高,均为100%;采场治理率最低,为66.21%。与2021年相比,2022年无新增地形地貌景观破坏图斑,新增1个治理完成图斑,面积11.87 hm^(2);仍有部分矿山未治理,用地类型主要为采场,图斑面积180.62 hm^(2),占密云区未治理图斑总面积的90%,对周边环境的影响较大。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.
