摘　　要：以2008年和2017年获取的广西贺州市里松-贺县地区的SPOT-5数据和国产GF-2卫星影像数据作为主要数据源,通过对影像数据进行处理,根据影像特征建立了研究区的矿山遥感解译标志,辅以野外验证,利用ArcGIS平台动态监测与分析了研究区矿山开发占地情况和矿山地质环境等问题,厘清了里松-贺县地区的矿山地质环境现状和变化趋势。研究表明:①研究区内2017年矿山开发占地总计1775.03 hm^(2),占整个研究区面积的1.26%。其中,矿山开采面占地达992.38 hm^(2),为矿山开发占地的55.91%。对比2008年和2017年的2期数据解译成果,得出2017年的矿山开发占损土地面积比2008年增长51.10%。②研究区的矿山开采引发了滑坡、崩塌、泥石流、不稳定斜坡等地质灾害共计121处,面积达133.48 hm^(2)、开采面占用的土地植被破坏严重、矿山开采也引发了水土和粉尘污染等矿山地质环境问题。Taking the SPOT-5 data in 2008 and the domestic GF-2 satellite image data in 2017 of the Lisong-Hexian area,Hezhou City,Guangxi Province as the information sources,this work processed the data,and established the remote sensing interpretation mark of the mine in the study area according to the image characteristics,supplemented by field verification.The dynamic monitoring,analysis and research were carried out on the mine development land occupation and geological environment by using ArcGIS platform.The current situation and changing trend of mine geological environment in Lisong-Hexian area were clarified.The research results show that:①in 2017,the total area of mine development in the study area is 1775.03 hm^(2),accounting for 1.26%of the total area of the study area.Among them,the mining area accounts for 992.38 hm^(2),which is 55.91%of the mining area.Compared with the data interpretation results of the two periods in 2008 and 2017,it is concluded that the area of mine development in 2017 accounts for 51.10%more than that in 2008.②There are 121 geological disasters such as landslides,collapses,debris flow and unstable slopes caused by mining in the study area,covering an area of 133.48 hm^(2).The land and vegetation occupied by the mining face are seriously damaged,and mining also causes geological environment problems such as soil and water pollution and dust pollution.
