坡面侵蚀 meaning in Chinese
slope erosion
the erosion caused by sloping surfaces
Examples
- Theoretical analysis on direction of rain and rainfall corrosion of critical slope
降雨方向与坡面侵蚀临界坡度的理论分析 - On the other hand , the contributions of interrill and rill erosion to the total erosion are 35 % and 65 % respectively , and their spatial distribution characters are different form each other
其中细沟间侵蚀和细沟侵蚀对坡面侵蚀的贡献分别为35 %和65 % ，且在空间发生特征上具有此消彼长的关系。 - By placing different rare earth elements ( ree ) in different soil depth and different section across one slope in an indoor plot , one simulated rainfall was applied to study the spatial - temporal process both of depth and section erosion across one slope plot simultaneously
摘要室内交叉布设不同的稀土氧化物，通过人工模拟次降雨，在同一试验条件下，对坡面侵蚀沿顺坡方向和深度方向的演变过程同时展开研究。 - The hillslope erosion processes include soil separation , sediment transport and sediment precipitate , which these three process result from the rainfall splash erosion and runoff erosion . to study and analyze the happening and developing conditions of hydraulic , soil and terrain , and the mechanisms of transitions and influences of these processes each other is the prerequisite to set up physical model of soil erosion
