摘 要: 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0~1m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。 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.
