Abstract: In order to evaluate quantitatively hydrological effects, based on analyzing of the three key forestry hydrological functions, such as canopy interception, litter interception and forest soil water storage capacity, the hydrological effect of P. massoniana Lamb.in mountain of western Hubei has been studied systematically. The results showed that the canopy interception is 19.14% of the total rainfall, and 0.48% of rainfall transformed into stem flow. The canopy interception was exponential functional relation to its rainfall and through fall and stem flow are significant linear correlation. The maximum water-holding percentage of litter layer is 224.23%. The soil water holding capacity is 291.63 t/hm2.the hydrological function of P. massoniana Lamb. forest need to improve in study area.
