Abstract:: Based on core cutter method, an investigation on the porosity, water-holding capacity, infiltration rate of soils (0-60 cm) in 6 forest types was conducted at the Demonstration Area of Forest Health Management Project in Xinfeng County of Jiangxi Province in order to analyze their soils water conservation function and to evaluate forest health. The results indicated that the maximum of soils in 6 forest types ranged from 880.88 t/hm² to 1 007.36 t/hm², sequence of water-holding capacity was Phyllostachys pubescens forest>Cunninghamia lanceolata plantation>evergreen broad-leaved forest>Pinus taeda plantation>Pinus elliotⅡ plantation>Pinus. massoniana plantation; The infiltration processes of all soils could be fitted properly by using Horton model, the primary permeability rate and stable permeability rate of all soils varied from 0.163 mm/min to 4.433 mm/min and from 0.112 mm/min to 1.788 mm/min, respectively. The soil permeability of Ph. pubescens forests was the highest, and P. taeda plantation was the relatively lowest. All these findings suggested the order of water conservation function of soil for 6 forests was: Ph. pubescens forest>C. lanceolata plantation>P. elliotⅡ plantation>evergreen broad-leaved forest>P. massoniana plantation>P. taeda plantation.
