The hydrological effects of litter layer and soil water of three kinds of pure forest stands in Jiulongshan were studied. The results showed that the total litter storage capacity of Cotinus coggygria pure forest was the largest (13.15 t·hm-2), followed by Pinus tabuliformis pure forest (12.50 t·hm-2), while that of Platycladus orientalis pure forest (9.53 t·hm-2) was the minimum. The maximum water-holding capacity and the modified interception amount of C. coggygria pure forest were 28.73 t·hm-2 and 23.17 t·hm-2 respectively, while that of P. orientalis pure forest were only 12.67 t·hm-2 and 10.17 t·hm-2 respectively. The water-holding capacity of undecomposed litter got saturated in 10 hours, while the duration of semi-decomposed litter was 8 hours. The water absorption rate of the litter in undecomposed and semi-decomposed layers kept the highest for the initial 2 hours, and got stabilized after 4 hours. The water-holding capacity and immersion time of different litter layers followed a functional relation, so as the litter layers water absorption rate and the immersion time. The average soil bulk densities of P. orientalis pure forest, P. tabuliformis pure forest and C. coggygria pure forest were 1.30 g·cm-3, 1.23 g·cm-3, and 1.08 g·cm-3 respectively. The total soil porosities of C. coggygria pure forest, P. tabuliformis pure forest and C. coggygria pure forest were 49.63%, 49.49%, and 47.44% respectively. The soil effective water-holding capacities of, P. orientalis pure forest, P. tabuliformis pure forest and C. coggygria pure forest were 96.53 t·hm-2, 88.23 t·hm-2, and 69.00 t·hm-2. The relationship between soil infiltration rate and infiltration time was studied by fitting analysis, and the results showed that the relationship could be described by using the power function and all values of R2 were greater than 0.90.
