Quantitative analysis and monitoring of soil erosion based on RS and GIS technology: case study of Makeng area in Fujian Province

Mining environmental problems becoming increasingly serious is a key factor that prevents sustainable development of mining industry. Destruction of surface vegetation that cause soil erosion and ecological environment deterioration are some of the main problems of geological environment in mines. This paper takes Fujian Province Makeng area as an example, using RS technique to extract the vegetation cover and land use/cover change, and GIS technique to extract elevation and soil information. This research adopted an integrated application of RS and GIS spatial analysis functions which can quickly, accurately and economically be used to make the range and the quantitative analysis of monitoring and evaluation soil erosion in 1998 and 2004. The research outcome is a basis for the renovating mining environment and protecting eco-geological environment.
