| 摘 要： | 通过对西峰水保站１９６４－１９８０年径流小区观测资料的统计分析，结果表明，次暴雨侵蚀模数与径流深之间以幂函数相关为最好（ｇ＝ａＨ＾ｂ）。笔以单位面积、单位径流深的冲刷量均值做为描述土壤抗冲性的指标，并对其影响因素进行了分析。

| Abstract: | Based on statistical analysis of observed data of experiment of water and soil runoff plots at Xifeng soil and water conservation station from 1964 to 1980,it is proved that there is a very close corelation (y=aHb )between individual rain fall erosive modulus and depth of runoff,which is a power funetion. The unit individual runoff depth (KW )was as soil anti-scour index which was used to evaluate the faetors affecting soil anti-scourability. |
