基于RS和GIS的矿区水土流失定量监测方法研究——以福建省马坑铁矿区水土流失为例

Quantitative Monitoring Method of Soil and Water Loss in RS and GIS-Based Mining Area

水土流失是矿产资源开发中出现的主要地质环境问题之一。以福建省马坑铁矿区为例,尝试通过RS技术监测和提取研究区的植被覆盖度及土地利用变化的信息,运用GIS技术提取研究区的高程信息和土壤类型信息,然后综合运用RS技术和GIS空间分析功能,快速、准确、经济地实现了对1998、2004年两个时段内矿区水土流失范围与强度变化的定量监测与评价。

Soil and water loss is one of key geological environmental issues happened during the development of mineral resources.It monitors and collects the information of vegetation rate of coverage and variation of land utilization of the studied area by using RS techniques and taking Makeng Iron Ore in Fujian as an example.It uses GIS techniques to collect the information of elevation and soil category of the studied area and completes quantitative monitoring and evaluation on the scope and intensity of soil and water loss of the mining area for two time intervals of 1998 and 2004 quickly,accurately and economically by comprehensively using RS techniques and the spatial analytical function of GIS.
