- Abstract:
-
As one of the parameters describing soil infiltration capacity,soil saturated hydraulic conductivity (Ks) is also very important for infiltration and watershed hydrological modeling.The watershed in West of Shanxi province which is a national forestry ecology research station was analyzed by experiments,and infiltration characteristics from different types of land use were researched by contrastive analyzing.The results show that:Ks and non-capillary porosity,total porosity have significantly positive relationships,while a highly negative relationship shows between Ks and soil volumetric weight.On the condition of same exposure,Ks rises from top to base of the slope.On the condition of same slope segment,Ks is higher on apoco than that was on adretto.Ks changes obviously with the transforms of land use types.
