摘  要:
为了解水源地人工林生态系统土壤水分贮存与入渗特征,在阿什河上游光明沟小流域内,选取樟子松、红松、兴安落叶松3种人工林,采用环刀法对其土壤水分贮存量及入渗特征进行对比研究。结果表明:兴安落叶松人工林土壤密度较低,孔隙度和贮水能力较高,与红松人工林和樟子松人工林之间差异显著(P<0.05);10℃时的稳渗系数K10大小依次为兴安落叶松人工林(4.86 mm/min)>红松人工林(0.63 mm/min)>樟子松人工林(0.57 mm/min)。综合分析表明,兴安落叶松人工林土壤的涵养水源功能最强,樟子松人工林和红松人工林的较差。

摘  要:
In order to study the soil water storage and infiltration characteristics of artificial forest,3 artificial forests(Pinus sylvestris var.mongolica,Pinus koraiensis and Larix gmelinii) were selected in Guangming small watershed in the upper reaches of Ashihe river.The water storage and infiltration characteristics were studied using ring sampler method.The results show that Larix gmelinii,which is significantly different(P<0.05)from the others,has the lowest bulk density as well as the highest porosity and water storage ability.The stable infiltration coefficient at 10℃ of Larix gmelinii(4.86mm/min) is the biggest,followed by Pinus koraiensis(0.63mm/min) and Pinus sylvestris var.mongolica(0.57mm/min).The conclusion is that the water conservation function of Larix gmelinii is the best among the 3 artificial forests.
