摘要：对江西大岗山林区常绿阔叶林、杉木人工林和毛竹林土壤的容重、孔隙度、持水量和贮水量等物理性质进行了研究。结果表明：（1）常绿阔叶林、毛竹林和杉木人工林的土壤容重均随深度的增加而增加。在0～80cm的土层中，杉木人工林、常绿阔叶林和毛竹林的土壤容重分别为1．29g／cm^3，1．24g／cm^3和1．20g／cm^3。（2）随土层深度的增加，3种林型土壤的总孔隙度、毛管孔隙度、饱和持水量和毛管持水量均逐渐降低。（3）在0～80cm的土层中，常绿阔叶林的土壤总孔隙度和非毛管孔隙度最大，毛竹林次之；而常绿阔叶林土壤的毛管孔隙度最小，毛竹林最大。（4）在0～80cm的土层中，3种林型土壤的饱和持水量、毛管持水量和非毛管持水量均为毛竹林〉常绿阔叶林〉杉木人工林。在0～80cm的土层中，3种林型土壤的现有贮水量和饱和贮水量均为常绿阔叶林〉杉木人工林〉毛竹林。（5）毛竹林在0～40cm土层中，土壤物理性质明显优于另外两种林分。
Research on soil bulk density, soil porosity, soil water retaining capacity and soil water storage of evergreen broad-leaved forest, Cunninghamia lanceolata and Phyllostachys pubescens stands was carried out in Dagangshan mountain in Jiangxi province. The results showed that： （1） The soil bulk density of three forest types increased with the increment of soil depth. In the layer of 0 - 80 cm, the soil bulk density of Cunninghamia lanceolata, Phyllostachys pubescens stands and evergreen broad-leaved forest was 1.29 g/cm^3, 1.24 g/cm^3, 1.20 g/cm^3 respectively. （2） With the increment of soil depth, total porosity, capillary porosity, saturated moisture capacity, capillary holding capacity decreased gradually. （3） In the layer of 0- 80 cm, the soil total and uncapillary porosity of evergreen broad-leaved forest was largest and chat of Phyllostachys pubescens stands was least. However, the soil capillary porosity of evergreen broad-leaved forest was lowest and that of Phyllostachys pubescens stands was highest. （4） In the layer of 0-80 cm, the order of soil saturated, capillary and uncapillary holding capacity on soil was Phyllostachys pubescens stands, evergreen broad-leaved forest and Cunninghamia lanceolata. In the layer of 0 - 80 cm, the sequence of soil present and saturated water storage was Phyllostachys pubescens stands, evergreen broad-leaved forest and Cunninghamia lanceolata. （5） In the layer of 0- 40 cm, the physical characteristics of Phyllostachys pubescens stands were obviously better than those of the other two.
