Abstract

In order to know the soil permeability capability of three forest types of western Sichuan basin borders, China, an investigation was carried out in 2013. The result showed that the order of soil permeability capability was initial infiltration rate > average infiltration rate > stable infiltration rate, and the smallest of initial infiltration rate, and average infiltration rate, stable infiltration rate and accumulative infiltration rate were found in Cryptomeria fortune forest except initial infiltration rate of 0~20 cm soil layer. The biggest decreasing amplitude of infiltration rate of each soil layers was found in 0~20 cm layer. Kostiakov model was used to model the infiltration process curves, which could display the soil infiltration process of different forest types. The results of correlation between infiltration process and soil physics index showed that bulk density, soil depth had no significantly negatively relationship (P>0.05), and other soil physics had positive relationship (P>0.05).
