| 摘 要： | 张家口市水保试验站坡长小区五年观测资料表明，降雨强度影响径流量、侵蚀量随坡长的变化。降雨强度较小时，径流量不能用坡长与降雨强度的乘积代替，侵蚀量随坡长增加较慢。降雨强度较大时，径流量可用坡长与降雨强度的乘积代替，侵蚀量方程中坡长指数较大。

| Abstract: | Based on observation data of experiment plots at the City of Zhangjiakou,analysis was made on the effect of rainfall intensity on the relationship among slope length,runoff and soil loss.While rainfall intensity was low,runoff did not increase linearly with slope length,and soil loss did not increase significantly with slope length.When rainfall intensity was high,runoff could be replaced by slope length plus rainfall intensity,and soil loss increased significantly with slope length. \ \ |
