基于RUSLE的大通县土壤侵蚀量估算
Estimation of Soil Erosion Based on RUSLE in Datong County
摘要
Abstract
Datong is located in the transition zone of Qinghai-Tibet Plateau and the Loess Plateau, a very important ecological area. Based on soil erosion prediction model (RUSLE) and GIS technology with the application of remote sensing in 1995 and 2005, the quantitative soil erosion and the transformation status of Datong county were esimated. The actual quantity of soil-erosion and the soil erosion modulus were 2 938. 17×104t, 68.55 t · hm-2 · a-1 and 2 160. 07×104 t, 51.83 t · hm-2 · a-1, respectively in 1995 and 2005, indicating that soil-erosion status was improving gradually with the reduction of soil-erosion quantity from 1995 to 2005.关键词
