| Abstract: | The soil erosion processes in the Loess Plateau may be divided into three types: namely, waterflow erosion; gravitational erosion; wind erosion. The waterflow erosion is most widely distributed and is the main erosion action in the Loess Plateau. The main factors dominating the occurrence and development of the soil erosion in the Loess Plateau are: 1. rainfall; 2. topography; 3. vegetation; 4. soil character. The energy of erosion action depends upon the rainfall and topography, but erodiblity depends upon the vegetation and soil properties. The degree of soil erosion in the Loess Plateau changes with variations of interaction of erosion and anti-erosion measures. |
