摘要
Important factors that influencing soil erosion, vegetation coverage and land slope as well as land use types, are obtain by means of RS and GIS in the Nantong coal mining area. Soil erosion type and areas are calculated by space analysis of GIS. The results of the study show that soil erosion area is 262.91 km2 in the Nantong coal mining area. Soil erosion intensity is mainly slight and moderate.According to the regional land types and characteristics of soil erosion, the investigated area is divided into three regions with different types. The eroded area in the mid-intensity erosion grade hill on the edge of the basin is large, and the main erosion type is mid-grade. The main erosion type is slight in the flat lower mountain mid-slight erosion region in the north. In middle mountains on the edge of the basin, the main erosion type is slight with large non-erosion area.
