Research on Soil Erosion Using Remote Sensing Method in Danjiangkou Reservoir--A Case Study of Shangnan County
摘要
Abstract
The current status of soil loss in 698 small watersheds in Shangnan County in Danjiangkou Reservoir area was investigated based on the quantitative remote sensing model(QRSM). The results showed that the area for weak erosivity and slight erosivity occupied 63.43%of the total study area, the amount of soil loss accounted for 5.27%of total soil erosivity, which focused on the treated area of north and south part of of Shangnan county. The percentage of the area for slight erosivity and above reached to 57.92%. The area for high erosivity and vio-lent erosivity was up to 20.4%of total area, and the soil loss up to 87.14%, which mainly located in the region along the main river around the county city. From the small watershed, the amount of the watershed with the area of slight and moderate erosivity exceeding 40%was up to 560 watersheds, and occupied 80.2%of the total small watersheds in the county.关键词
