| 摘 要： | 根据调查和模拟降雨试验资料分析，黄土高原地区降雨是影响土壤侵蚀的最重要因素之一。水土流失主要是由少数几次大雨或暴雨所引起，大多数的降雨一般不产生地表径流；能够引起水土流失的土壤侵蚀暴雨标准随雨强和历时而异；ＥＩ３０是较适用的降雨侵蚀力指标，各种降雨特征值具有明显的空间分布规律。

| Abstract: | Based on field investigation and analyses on the data obtained from simulated rainfall experiments,soil erosion is heavily affected by rainfall and are mainly caused by a few of heavy rain in Loess Plateau.There is no surface runoff in most cases when rained.The standard of soil erosion rainstorm was drew up preliminarily.Discussion is made on spatial distribution of various rainfall features. |

| Keywords: | Loess Plateau soil erosion rainfall feature |
