Abstract Characteristics of soil water infiltration and water-holding of typical forest stands in Yimeng Mountainous forest area are researched by using forest hydrology principle and method,in order to offer references for the choice of proper forest community types and allocation model in the course of vegetation construction.Results indicate that: 1) The forest stand has an obvious effect on increasing the soil porosity,the soil water holding amount and the soil water infiltration rate.And for these effect,the mixed forest stands are much better than pure forest,the broadleaf forest stands are much better than coniferous forest stands.2) The degree of improvement of forest vegetation on soil non-capillary porosity water-holding amount is greater than on soil capillary porosity water-holding amount,so the forest vegetation has an obvious effect on water conservation.3) Both Horton infiltration model and Kostiakov infiltration model can simulate the soil water infiltration process of each forest vegetation type in research area well.But the applicability of the Common experienced infiltration model and Philip infiltration model are worse.There is a clear linear positive correlation between the soil water infiltration rate and the soil porosity.
