| 摘 要： | 通用土壤流失方程USLE与水蚀预测模型WEPP是当前常用的两种土壤侵蚀预测模型,而WEPP物理模型代表着土壤侵蚀预测预报的发展方向。对USLE中的K因子与WEPP中的Ki、Kr因子进行相关分析表明,USLE中的K因子与WEPP中的Ki、Kr因子之间几乎毫无相关性。即无法通过对USLE中可蚀性因子的分析来确定WEPP模型中可蚀性因子的大小。

| Abstract: | At present, USLE and WEPP are the two predicting models for soil erosion in common use and WEPP physical model represents the development orientation of predicting and forecasting of soil erosion. The paper conducts correlation analysis on K factor of USLE and factors of K_i and K_r of WEPP and shows that there is almost no correlativity between K factor of USLE and factors of K_i and K_r of WEPP. Thus, it is impossible to decide the size of erodibility factor of WEPP through the analysis of erodibility factor of USLE. |
