- Abstract:
-
The soil permeability charateristics of the third subdivision-Lǔergou small basin in Loess Plateau hilly-gully regionis were studied with double-ring method based on field investigation. The results showed that the soil permeability coefficients were closely to different land uses, and the soil permeability coefficient of locust forest is the biggest, the coefficients in the cultivated land and orchard are the smallest. Analyzing on the whole basin, the soil permeability coefficients did not obviously presents middle reaches > downstream > upstream, and right side > left side. The soil permeability coefficients is well related to bulk density and non-capillary pores, and the soil permeability coefficients is mainly controlled by non-capillary pore. Soil permeability coefficients fitting precisions with Horton’s model are perfect and the correlation coefficient is 0.930.
