Abstract:: Understanding the function of water conservation of forest has been a hot topic in ecology and hydrology research. Six types of forestlands in Lushan nature reserve of Jiangxi were taken as the study sites.Soil physical properties and water conservation function were analyzed in this study. The results showed that the litter storages of various forestlands were 5.48~23.19 t/hm². The water-holding capacity of the litter layer of deciduous broad-leaved (DBF) forestland was higher than other forestlands. Average soil hardness of different forestlands was 13.24~25.43 kg/cm². The soil bulk density of various forestland decreased in the order of Huangshan pine (HsP) forest > Yushania (Ys) forest > evergreen-deciduous broad-leaved(EDBL) forest > deciduous broad-leaved(DBL) forest > evergreen broad-leaf forest (EBL) forest > Pinus (PM) forest. In the case of soil seepage velocity, the order of velocities of various foresland was PM > DBL > EBL > HsP > Ys > EDBL. The calculated forestland soil maximum storage capacity followed the order of DBL > PM > EBL > HsP > Ys > EDBL, and the water conservation quantities of various forestland was in the sequence of DBL > PM > EBL > HsP > EDBL > Ys.
