TM影像在尾矿库水质监测中的应用

Application of TM image in Monitoring the Water Quality of Tailing Reservoir

为定量描述矿区尾矿库水质情况,采用TM影像,参考前人建立的水质遥感监测模型,对虎山尾矿库的主要水质指标含量进行估算。根据估算的指标值将尾矿库水体的受污染程度划分成严重、较严重、一般3个等级,并结合野外实地考察情况进行比较分析。再次证明,利用RS技术结合GIS空间分析能对矿区尾矿库的水体污染状况进行快速、高效的监测。

By using the TM image data and the existing models of water quality parameters inversion based on remote sensing data,the estimation of main water quality indexs of Hushan tailing reservoir was carried out. According to estimate results,the pollution level of waters in the tailing reservoir was graded as ＂ serious＂ ,＂ relatively serious＂ and ＂ common＂ ,Combined with the field investigation,the pollution of waters was analyzed and compared. It was proved that RS technology combined with GIS spatial analysis can monitor water pollution in tailing reservoir quickly and efficiently.
