- Abstract:
-
In order to prevent and treat soil erosion in the ecologically fragile area, taking the upstream of the ten tributaries as the research area, we used the RUSLE model and land-based methods through GIS software, selected 5 typical years of 1980, 1990, 2000, 2010 and 2018, respectively, and studied the dynamic characteristics of the spatial distribution of soil erosion in the upstream of the ten tributaries and compared the effectiveness of the two methods. The results show that the soil erosion in the upstream of the top ten tributaries is mainly non-obvious erosion and moderate erosion, and the calculated erosion area of mild or above grade based on the two methods shows a trend of increase in 1980—1990 and decrease in 1990—2018, respectively, indicating that the soil erosion situation in this region is gradually improved. It is found that the factor of RUSLE equation is more comprehensive, the simulation is closer to the reality, and is also applicable to the quantitative study of water and soil loss by comparing the two methods.
