摘要
结合矿区4期不同时相遥感影像,在RS和GIS软件支持下,采用加权综合评价法,对矿区水土流失状况进行信息提取并分析。研究表明,该方法水土流失信息的提取精度达到85%以上,可有效提高矿区水土流失监测的效率,节省大量人力物力。
Using weighting comprehensive evaluation method,according to the remote sensing images at different phases based on GIS and RS,we extracted and analyzed the soil and water loss information in mining area.The research results show that this method can make the information extraction accuracy above 85%,and improve efficiency in soil and water loss dynamic monitoring in mining area based on the soil and water loss.
