| 摘 要： | 该对四川省农业科学院资阳水土保持试验所布设的７种土壤试验小区，用模拟降雨装置进行了土壤抗蚀性能的初步试验研究，结果表明：（１）７种土壤的抗蚀能力大小依次为：冷沙黄泥＞棕紫泥＞红棕紫泥＞灰色潮土＞红紫泥＞黄红紫泥＞暗棕紫泥；（２）７种土壤的么径流过程累积量与降雨历时、产沙过程累积量与降雨历时，径流过程累积量与产沙过程累积量之间均有显的线性相关关系，以及６种土壤的土壤含水量与开始产流时间之间有非常

| Abstract: | Soil erodibility of seven soils located in ziyang soil and water conservation fieldstation ofsichuan Academy of Agricultural sciences,ziyang,was studied under rainfall simulator.The resultshows:1.the soil erodibility of seven soils is yellow earthbrown purple soilred brown purplesoilgrey alluvial soilred purple soilyellow red purple soildarkbrown purple soil;2.thereis a significant linear relationship between runoff and rainfall duration,soil loss and rainfall duration, runoff and soil loss for seven soils,and Clear non linear relationship between soil moisture contentand runoff starting time for six soils. |
