| 对蕉岭长潭省级自然保护区的阔叶混交林、马尾松林、杉木林、毛竹林、针阔混交林等五种典型林分的土壤水分物理性质进行了研究，结果表明(1)五种林分类型土壤自然含水量、毛管持水量、最小持水量的排序为毛竹林＞针阔混交林＞马尾松林＞杉木林＞阔叶混交林；非毛管孔隙度和非毛管持水量的排序为针阔混交林＞阔叶混交林＞杉木林＞马尾松林＞毛竹林。(2)五种林分的非毛管孔隙度；阔叶混交林、杉木林、针阔混交林的总孔隙度；阔叶混交林的毛管持水量、最大持水量、最小持水量、非毛管持水量；针阔混交林的自然含水量、毛管持水量、最大持水量、最小持水量、非毛管持水量都是随着土层深度的增加而减少。阔叶混交林、毛竹林、杉木林、针阔混交林的土壤容重是随土层深度的增加而增加。(3)同一土层不同林分间的容重、孔隙度、自然含水量、最大持水量、毛管持水量、非毛管持水量和最小持水量都没有显著差异，而同一林分的物理性质和持水特性在不同土层之间存在显著性差异。 |

| Abstract: |
| The article makes research on soil moisture physical of broad leaved mixed forest、pine forest、fir forest、Phyllostachys edulis forest、mixed broadleaf-conifer forest in JiaoLing Changtan natural reserve, Guangdong. The result showed that: 1.sequence of soil natural water content、capillary moisture capability、min water retention capability on five forest style is same: Phyllostachys edulis forest＞mixed broadleaf-conifer forest＞repine forest＞fir forest＞broad leaved mixed forest;sequence of non-capillary porosity and non-capillary moisture capability is same: mixed broadleaf-conifer forest＞broad leaved mixed forest＞fir forest＞repine forest＞mao bamboo forest.2.non-capillary porosity of five forests; total porosity of broad leaved mixed forest、fir forest、mixed broadleaf-conifer forest; capillary moisture capability、max water retention capability、min water retention capability、non-capillary moisture capability of broad leaved mixed forest；natural water content、capillary moisture capability、max water retention capability、min water retention capability、non-capillary moisture capability of mixed broadleaf-conifer forest all decrease with the increase of soil depth. Soil capacity of broad leaved mixed forest、repine forest、fir forest、mao bamboo forest increase with the increase of soil depth.3.no matter which soil, there is no obvious difference between capacity、porosity 、natural water content、max water retention capability、capillary moisture capability、non-capillary moisture capability and min water retention capability. But there is difference between different soil for the physical property and water retention capability of the same tree. |
