中文摘要	通过室内人工模拟降雨试验研究降雨强度、坡度两因素与沂蒙山区典型土壤坡面产沙的关系。结果表明:土壤侵蚀量随雨强、坡度的增大而增加,但增加幅度不同。降雨强度、坡度的增大会加速坡面细沟的出现及其演变,且细沟的产生会引起产沙率急剧增加,并表现出一定的波动性。对于棕壤,小雨强时,坡面变化是影响坡面侵蚀产沙的主要因素,当雨强逐渐增大时,雨强对侵蚀产沙的影响逐渐超过坡度。对于褐土,雨强一直是影响坡面侵蚀产沙过程的主导因子。在相同雨强、坡度条件下,棕壤坡面的产沙率、土壤侵蚀量始终要高于褐土。
英文摘要	The laboratory experiment was conducted under simulated rainfalls to research into the relationship between rainfall intensity, soil slope and the sediment yield of Yimeng mountain typical slope surface. Amounts of soil erosion increased with rainfall intensity increases. The increase of rainfall intensity and slope gradient can accelerate the occurrence and changes of rills, and the sediment delivery rate is drastically increased due to the occurrence and development of the rills, and presents certain fluctuations. For the brown soil, change of slope surface is the main factor generating sediment production and erosion during a small rainfall. When the rainfall intensity strengthened, the effects caused by rainfall intensity could gradually exceed that caused by slope changing. For the cinnamon, the change of rainfall intensity is always the main factor to affect the process of desertification. When the rainfall intensity and slop were all the same, the sand generate rate and soil erosion amounts with brown soil could always exceed with cinnamon.
