Abstract:

Erosion is one of the land degradation causes, having seriously effect on the living environment and manufacturing activities, especially in the upland and agricultural areas. Many studies in the world show that, remote sensing and GIS techniques can be used effectively for monitoring and assessing soil erosion. This paper present the results for soil erosion mapping using the Universal Soil Loss Equation (USLE) in Huong Hoa district, Quang Tri province. Landsat multispectral images period 2010 - 2017, rainfall, terrain and soil data to map the USLE factor layers and predict the long-term average annual soil loss. The results obtained show that, along with the decline of forest cover, the area of extremely strong erosion increases very quickly in period 2010 - 2017, from 27,08% of the total area of the study area to 48,91% in 2017.
