摘要
德兴铜矿矿山多年开采对矿区生态环境造成极大的损害,为维护矿区可持续发展,生态损害现状调查尤为重要。利用ASTER数据结合野外实测各类地物反射光谱曲线,利用矿物指数提取矿区重金属和粘土污染;采用差值法提取水体污染状况;采用NDVI彩色密度分割法提取矿区植被污染信息。研究表明,铜矿区生态损害现状甚为严重,利用遥感手段监测矿区生态环境是完全可行的。这为矿区土地复垦与生态修复提供了技术支持和决策依据。
Many years＇ exploitation of Dexing copper mine has damaged ecological environment. In order to maintain sustainable development of mine, survey of state of ecological damage is becoming more and more important. Heavy metal and clay pollution information of waste ores has been extracted by mineral index and water pollution information by difference method and vegetation stress by density slice of NDVI based on ASTER data and reflectance curves of objects measured in the field. The result shows that the state of ecological damage is very serious. Monitoring ecological environment of mine by Remote Sensing is completely possible. It will support technically and provide decision basis for land reclamation and ecological restoration.
