摘　　要：准确快速评价矿山重金属污染修复效果对于矿山生态恢复与重建治理工作具有现实意义。本文选取了某一矿区的最新Hyperion高光谱卫星数据,用Arcgis、Mapgis、ERDAS软件对遥感图像处理,根据矿区内典型植物中重金属含量与光谱特征参数的对应关系,进而实现对矿区内植被富集重金属动态监测。研究发现,长势较差的植被主要分布于1、2号尾矿库以及周边受矿山废水影响较大的河流两岸;较于十年前,矿区大部分区域植被重金属含量显著降低,但仍有部分区域需采取修复措施。这些结论可为矿山环境监测、矿山合理开发与生态文明建设提供服务。Evaluating the remediation effect of heavy metal pollution in mines rapidly is of practical significance to the ecological restoration and reconstruction of mines.Dexing copper mine has been exploited for decades in Jiangxi province.Large amount of the wasted stones and tailings are produced in the mining process.This paper chooses the recent hyperspectral remote sensing date of Dexing Copper mine.The relationship between heavy metal content and red edge position(a spectral characteristic parameter) was analyzed.All the data are managed by ArcGIS,MAPGIS and ERDAS.Drawed the following conclusions:The distribution of the worse and general growing vegetation is around mine tailings nos.1 and 2;the distribution of growing better vegetation in the study area is the area that is far away from areas heavily polluted and higher area in the southeastern mining.Compared with ten years ago,the content of heavy metals in vegetation in most areas of the mining area was significantly reduced,but some areas still needed to take restoration measures.The results show that they can offer the mine reasonable development,environmental monitoring and and ecological civilization construction.
