In order to better understand the characteristics of soil water under different land use modes,the physical and chemical properties of the soil was analyzed with the saturated hydraulic conductivity(K)tested in laboratory by soil water lysimeter and the correlations between the soil saturated hydraulic conductivity and its physical and chemical properties was achieved.The saturated hydraulic conductivity of the soil was decreased with soil depth while the K,was in the decreasing order in the forestland,field ridge and farmland.The K,had the significant correlationship with the soil bulk density,non-capillary porosity and water-stable aggregates(>0.25 mm) and organic content. It is suggested that the forestland,filed ridge,farmland should be deployed rationally with the reduction of the abandoned land to improve the permeability and texture of the soil.
