摘　　要：目前 ,铁路建设环境影响评价中一般采用 U SL E预报沿线水土流失量 ,国内某些地区已有适用于当地的区域性预报方程。本文通过对比分析 ,发现直接采用 USL E预报沿线水土流失量误差较大 。At present, the USLE was usually used to predict the loss of soil and water along railway in the evaluation of the influences on the ecological environment due to railway construction, and there had been several regional prediction equations in our country. In the paper, by comparison and analyzing, it was found that using USLE directly to predict loss of soil and water along railway can lead to much error. In the end of the paper, several suggestions about predicting loss of soil and water along railway were proposed.
