摘要
以吉林省辽源市煤炭矿山为研究对象,通过对SPOT5卫星影像纠正、融合、解译等处理,快速、便捷地查清矿区的地质环境问题:矿区固体废物堆放、尾矿库分布情况;矿山采空区地面塌陷、山体开裂、滑坡、崩塌、泥石流、岩溶塌陷、煤田自燃等地质灾害分布情况;由矿产开发引发的水土流失、土地沙化、侵占土地、植被破坏的情况;矿区水体、植被、土壤污染状况等。通过矿山地质环境调查实践,总结出了SPOT5卫星影像最优波段组合、融合方法及矿山地质环境调查中的地物判读标志,从而使SPOT5卫星影像在遥感环境地质调查中发挥了重要作用。
The coal mines in Liaoyuan City, Jilin Province as the research object, through the SPOT5 satellite image rectification, fusion, translation and other processing solution, it can fast, conveniently identify mine geoenvironment problems: mine solid waste dumps, tailings distribution; mining empty area, ground subsidence,mountain cracking, landslide, collapse, debris flow, karst collapse, coal spontaneous combustion and spatial distribution of geological disasters; water and soil loss, land desertification, land occupation, vegetation deterioration, water pollution, vegetation pollution, soil pollution in the mines. Finally, this paper summaries the SPOT5 satellite image optimum band combination, fusion method of mine geological environment survey and the features in the interpretation signs, so that the SPOT5 satellite images play an important role in remote sensing in environmental geological survey.
