| 摘 要： | 降雨侵蚀力反映由降雨引起的土壤侵蚀的潜在能力，是建立通用土壤流失方程USLE的最基本因子之一。由于降雨侵蚀力计算过程中所需资料较难收集，给其计算增加了难度。利用福建省46个代表性气象站资料，建立了利用经度、纬度、海拔高度以及月降雨量估算降雨侵蚀力的简易算法模型，结果表明该模型预测预报效果较好，能够用于估算平均降雨侵蚀力。

| Abstract: | Rainfall erosivity reflects the potential ability of the soil loss caused by rainfall and it is very important for predicting soil loss quantitatively.Two rainfall erosivity models basing on longitude,latitude,height above sea level and monthly rainfall amount to estimate rainfall erosivity directly were established from data of 46 weather stations in Fujian province.The models worked very well and could be used to estimate the average rainfall erosivity. |
