经近几年的观测和理论分析，取得了以下结果和创新的认识： 1 )在降雨强度较大的情况下，保护性耕作制? ?聚土免耕的产沙强度明显较常规耕作制? ?顺坡耕作的小，说明聚土免耕耕作制防治土壤流失是有效的；但当土壤达到饱和后，聚土免耕的径流强度与常规耕作的差异较小，产沙强度也增大，因此，聚土免耕防治水土流失的能力是有限的。 | | 8. | For this reason , our objective is the research of the mechanism of runoff generation and characteristics of moisture changing process of slope farming purple soil , accordding to the theory of hydrology and the intergrated - means of compined the hydrology with the peodology , because it is the basis of the studies : soil erosion and protection , farming - land water balance , non - point pollute , etc . , and the direction gist of runoff arrange implement , solving water hazard and management of irrigation and fertilizer
