摘　　要：基于均质土壤的非充分供水入渗试验数据,通过回归分析的方法,分析讨论了Kostiakov二参数模型、三参数模型、Horton模型和Philip模型,对非充分供水条件下土壤控制阶段入渗过程的适用性。结果表明:Kostiak-ov二参数模型、三参数和Philip模型的显著性和相关性都较高;综合考虑Kostiakov三参数模型的显著性、相关性以及回归参数与实际入渗过程边界值的吻合性,认为用Kostiakov三参数模型描述土壤入渗能力控制阶段入渗特性效果最好。On the basis of the non-sufficient infiltration test of homogeneity soil, the paper discussed Kostiakov two parameter model, Kostiakov three parameter model, Horton model and Philip model, and analyzed the fitness for the infiltration process of Non-sufficient water supplied soil control stage by using the regression method. The result shows： the first is that significance and relevance of Kostiakov two parameter model, three parameter mode and Philip model is rather high; the second is that the effect of infiltration characteristics by describing in Kostiakov three parameter model is the best in soil control stage by further thinking the significance, relevance and the regression parameter fitness reality infiltration border of Kostiakov three parameter model.
