长潭省级自然保护区森林土壤孔隙贮蓄水分与现实吸持能力关系研究

为了建设高效的水源涵养林、正确评价森林的生态系统服务功能，笔者在广东省长潭省级自然保护区对0~1 m厚土壤层的孔隙贮蓄水分与现实吸持水分能力的关系进行了研究。结果表明，长潭保护区中，现实贮蓄水分数量受到土壤总孔隙贮蓄、毛管孔隙贮蓄和非毛管孔隙贮蓄的显著影响，而可有效吸收数量仅受到非毛管孔隙贮蓄的显著影响。在各显著回归关系中，除现实贮蓄水分数量与非毛管孔隙贮蓄表现为负的相关外，其余均为正相关关系。

Studies on the Relationship Between Water Storage of Pore of Forest Soil and Holding Capacity in Changtan Provincial Nature Reserve

In order to establish cost-effective water resource conservation forest and precisely evaluate the forest ecosystem service, the relationships between water storage of pore of forest soil and holding capacity for 0-1 m depth soil in Changtan Provincial Nature Reserve in Guangdong Province were studied. The results showed that: the extant water storage was affected significantly by the total water storage, the capillary storage and the non-capillary storage, whereas the available water storage was only affected significantly by the non-capillary storage. The relationship between capillary storage and the extant water storage were negatively correlative and the others were positively correlative.
