Abstract:: Different types of forest community in medium altitude of north Qinling Mountain were chosen to study the soil water physical characteristics. Result showed that in these forests, the soil bulk densities, non-capillary porosity, maximum water-holding capacity, capillary water-holding capacity and field water-holding capacity were ranked as mixed forests>deciduous broadleaved forest, while soil non-capillary porosity water-holding amount of 40cm layer was ranked as mixed forests>deciduous broadleaved forest. Permeability of mixed forest was 4.97 times higher than deciduous broadleaved forest and its mean permeability reaches 6.93 mm/min. Permeability of 0-20 cm layer was higher than that in 20-40 cm layer in different types of forest soil. Based on principal component analysis, the comprehensive hydrological effect of oak and pinus tabulaeformis(Pinus armandii) was the highest.
