The research showed that pam could improve soil structure , and greatly increase the stabilization of soil aggregates , so soil crust development would be decreased . fifthly , soil grain that controls rainfall splash erosion was obtained , the influence of soil clay was very great during initial stages of rainfall . with rainfall going on , soil coarse sand and fine sand would control the splash erosion
五、控制土壤溅蚀的主要土壤粒级：在降雨初期土壤的的粘粒对溅蚀速率的影响较大，随着降雨历时的延长，土壤中的细砂和粗砂成为溅蚀速率影响较大的因子；六、对土壤溅蚀影响较大的土壤结构特征因子：降雨5分钟时，土壤的渗透系数对溅蚀速率的影响较大，随着降雨的继续进行，土壤的团聚度一直对土壤溅蚀速率影响较大。
