应用江西省10个县（市）典型沙土流失42个小区的试验观测资料，分析了红壤丘陵水力侵蚀区降雨与土壤侵蚀的关系。结果表明：土壤侵蚀量与降雨量、降雨强度以及两者乘积存在着显著的相关性，且降雨量、降雨强度两者的乘积与土壤侵蚀量之间的相关性更为显著；在第四纪红壤坡地和花岗岩发育红壤坡地，分别采用幂函数方程和二次曲线方程揭示降雨因子与土壤侵蚀之间的内在规律。

With observation data of 42 runoff plots,the paper analyzed the relationship between rainfall factors and soil erosion in red soil hilly region. The results showed that amount of soil erosion was closely related to rainfall amount,rainfall intensity and the two arithmetic product. Compared with rainfall amount and rainfall intensity,amount of soil erosion was most closely related to their product. Power function equation:A=b0 (PI)b1 can explain the relationship between the factors of rainfall and soil erosion in quaternary red soil slope,and quadratic curve equation:A=b0+b1(PI)+b2(PI)2 in granite red soil slope.
