运用坡面径流小区法，研究了闽北裸露坡地水土流失与不同雨强的关系，结果表明：1）裸露坡地径流量受雨强的影响较小，小雨和中雨时径流量与雨强呈线性相关，大雨时径流量与雨强不相关．2）雨强对土壤流失量的影响高于对径流量的影响．在降雨量相近的情况下土壤流失量与平均雨强呈线性关系．3）各时段雨强与裸露坡地的土壤流失量的相关性表现为，I10〉I30〉I60，在不同雨型时均以I10的拟合效果最好．

The relationship between rainfall intensity and soil and water losses of bare sloping land in Northern Fujian was investigated by the establishment of runoff equation. The results indicated that the runoff in bare sloping land was not closely related to the rainfall intensity, for example, under the condition of light or moderate rain, the runoff in bare sloping land and different rainfall intensity had a linear correlation, but for heavy rain, the relation could not be explained by functions. The effects of rainfall intensity on soil loss were more significant than on runoff. When the amount of different rainfall was close, the relationship between soil loss and average rainfall intensity was found to be consistent with the linear function. The relationship of different rainfall intensity and soil loss in bare sloping land was in the order of I10 〉 I30 〉I60.
