摘要：对广东乐昌杨东山十二度水自然保护区阔叶林的土壤密度、孔隙度、持水量和蓄水能力等物理性质进行了调查研究。结果表明:(1)土壤密度均随深度的增加而增加,调查样地表层的土壤密度在0.79～1.08 g.cm-3之间,0～100 cm土层的平均土壤密度在1.09～1.34 g.cm-3之间,西南坡向样地的土壤密度小于西北坡向样地;(2)随土层深度的增加,调查样地土壤的毛管孔隙度、总孔隙度均逐渐降低,0～100 cm土层毛管孔隙度均值为35.80%～39.41%,总孔隙度均值为46.56%～52.39%;非毛管孔隙度随土层的变化规律不明显,0～100 cm土层的非毛管孔隙度为5.13%～15.41%;(3)随土层深度的增加,调查样地土壤的饱和持水量和毛管持水量均逐渐降低,0～100 cm土层的饱和持水量均值为36.76%～51.52%,毛管持水量均值为22.78%～37.68%。(4)调查样地0～100 cm土层蓄水能力值范围为41.31～153.55 mm,饱和蓄水量为446.63～504.27 mm。
The investigations on soil bulk density,soil porosity,soil water holding capacity and soil water storage of broad-leaved forest were carried out in YangdongshanShierdushui provincial nature reserve in Lechang,Guangdong province.The results indicate that：（1） The soil bulk density of sample plots increased with the increment of soil depth,with the average of 0.79 ～ 1.08 g.cm-3 in the surface layer,and the average of 1.09 ～ 1.34 g.cm-3 in the layer of 0 ～ 100 cm.Basically,the soil bulk density of South West slope plots was less than that of North West slope plots.（2） Total porosity and capillary porosity of sample plots decreased with the increment of soil depth.The total porosity,capillary porosity and non-capillary porosity were 46.56% ～ 52.39%,35.80% ～ 39.41%,and 5.13% ～ 15.41% respectively in the layer of 0 ～ 100 cm.（3） The saturated water holding capacity and capillary water holding capillary of sample plots decreased with the increment of soil depth.The average saturated water holding capacity and capillary water holding capillary were 36.76% ～ 51.52% and 22.78% ～ 37.68% respectively in the layer of 0 ～ 100 cm.（4） The soil water storage capacity and the saturated water storage capacity were 41.31 ～ 153.55 mm and 446.63 ～ 504.27 mm respectively in the layer of 0 ～ 100 cm.
