Description
Summary:In order to learn the relevant characteristics of soil erosion of highway slope in the permafrost region of the Qinghai-Tibet Plateau, the different characteristics of the erosion area were analyzed in this paper firstly. Then based on ArcGIS and RUSLE modes and gray correlation analysis, the spatial and temporal differentiation characteristics of soil erosion in the area were proposed. The results showed that soil erosion was mainly concentrated in June to September, and the date of the project construction should be avoided as much as possible; The erosion intensity was slightly and mildly and gradually weakened from south to north. Theoretical research results will have important theoretical and technical significance for the prevention and control of soil erosion of highway slope in the permafrost area of the Qinghai-Tibet Plateau.
