  1. 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、控制土壤濺蝕的主要土壤粒級:在降雨初期土壤的的粘粒對濺蝕速率的影響較大,隨著降雨歷時的延長,土壤中的細砂和粗砂成為濺蝕速率影響較大的因子;六、對土壤濺蝕影響較大的土壤結構特徵因子:降雨5分鐘時,土壤的滲透系數對濺蝕速率的影響較大,隨著降雨的繼續進行,土壤的團聚度一直對土壤濺蝕速率影響較大。
