Abstract:: Four kinds of typical forests in Fengning County were taken as the research objects, indoor immersion method and ring knife immersion method were adopted to determine the water holding capacity, water absorption rate and soil physical properties of litter, and the hydrological effect was studied. The results showed that the total accumulation of litter was 9.58~11.50 t/hm², the volumes decreased in the order: poplar theropencedrymion > shaw > poplar broad-leaved mixed forest > elm broad-leaved mixed forest; the maximum water holding capacity of poplar broad-leaved mixed forest was 14.56 t/hm², and the maximum water holding rate was 295.46%; the average soil bulk densities were between 0.77~0.98 g/cm³; the densities decreased in the order: poplar theropencedrymion > shaw > poplar broad-leaved mixed forest>elm broad-leaved mixed forest; the total soil porosity was 48.98%~56.72%, the largest was found in the poplar broad-leaved mixed forest, the minimum was observed in shaw; the maximum soil water holding capacity was 623.67~726.33 t/hm², and the maximum water holding capacity of maximum value was 1.16 times as much as that of the minimum. The initial infiltration rate of soil varied from 23.95 mm/min to 28.12 mm/min. The initial infiltration rate in poplar theropencedrymion was 28.12 mm/min, and the initial infiltration rate in elm broad-leaved mixed forest was minimum, it was 23.95 mm/min.
