Abstract:
Six runoff plots with different vegetation types were established to study the effects of rainfall on soil invasion under different vegetation conditions in the Lizikou small watershed. The results were as follows:(1) Under different vegetation conditions, rainfall impacts on soil erosion could be listed as the wasteland plots, the farming land, the forest land, in descending order. The soil erosion of forest land was weak, and the forest land strongly maintained local soil and water, which was most suitable as a plant measure for local soil and water conservation. (2) In general, it showed a significant positive correlation among rainfall, rainfall erosion and surface runoff, runoff depth and soil loss in the six runoff plots, indicating that rainfall had a strong local erosion effect, and needing people to focus on protection. The correlation was revealed between rainfall and soil erosion in the study area, the effects of rainfall were compared on soil erosion under different vegetation conditions, providing reference for related research on soil and water conservation.
