| 摘 要： | 本文通过对试验小区观测值的分析和研究,认为砂页岩山地土壤侵蚀性降雨因子,主要为降雨量的大小和10min时的瞬时降雨强度。随着降雨量和10min时的瞬时雨强的增大,土壤侵蚀量增加。试验结果表明:砂页岩山地土壤侵蚀的强弱,取决于10min时的瞬时雨强的大小。

| Abstract: | This paper holds that the erosive rainfall in the arenaceous shale mountain lands is the magnitude of rainfall as well as rainfall intensity within 10 minutes based on the analysis and study of the observed and measured date fron the runoff plots.With an increase in rainfall and rainfall intensity within 10 minutes,the volume of soil eorded goes up.The testing results show that the weakness and strongness of soil erosion in arenaceous shale mountain lands depends on the magnitude of rainfall intensity within 10 minutes. |
