| 摘 要： | 森林的水源涵养功能一直是生态学与水文学研究的重点内容。以江西庐山自然保护区6种不同林地为研究对象，对其土壤物理性质和水源涵养功能进行分析研究。结果表明，不同林地凋落物层贮量为5.48～23.19 t/hm2 ；落叶阔叶林地凋落物层的持水量远大于其它林地。不同林地土壤硬度平均值变化为13.24～25.43 kg/cm2 ；不同林地土壤容重大小排序为:黄山松林 > 玉山竹林 > 常绿—落叶阔叶混交林 > 落叶阔叶林 > 常绿阔叶林 > 马尾松林。从土壤的渗透速度来看，不同林地土壤的渗透性能依次为:马尾松林 > 落叶阔叶林 > 常绿阔叶林 > 黄山松林 > 玉山竹林 > 常绿—落叶阔叶混交林；不同林地最大蓄水量大小依次为:落叶阔叶林 > 马尾松林 > 常绿阔叶林 > 黄山松林 > 玉山竹林 > 常绿—落叶阔叶混交林；而其涵养水源量大小排序:落叶阔叶林 > 马尾松林 > 常绿阔叶林 > 黄山松林 > 常绿—落叶阔叶混交林 > 玉山竹林。

| 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. |
