以冀北山地不同抚育间伐措施后华北落叶松人工林的植被层、枯落物层和土壤层为研究对象,对其水源涵养功能进行了初步分析.结果表明:华北落叶松林植被截留能力和枯落物持水功能随着间伐保留密度的减小而减小;土壤蓄水功能随着间伐强度的增大表现出逐渐增大趋势.间伐后进行枯落物收集、清除等经营活动可增大植被截留功能和枯落物持水功能,但会降低土壤蓄水功能.从涵养水源功能的组成来看,土壤蓄水功能最大,其次是枯落物持水功能,植被截留功能最小.由此认为,对华北落叶松人工林进行合理抚育间伐,能增强林地涵养水源功能.

@@@@The water conservation function was studied for the Larix principis‐rupprechtii plantation after different thinning treatments based on the vegetation layer ,litter layer ,and soil layer of the plantation in the mountainous area of north Hebei province .The results showed that the vegetation interception and litter water retention capacities decreased with the decreasing of thinning reserve density ,and the soil water storage capacity increased with the increasing of thinning intensity .Collecting and removing litter after thinning could increase the vegetation interception and litter water retention capacities but decrease the soil water storage capacity .Soil water storage capacity was the most important in the vegetation water conservation function ,fol‐lowed by the litter water retention capacity .Vegetation interception capacity was the least important .A reasonable thinning on the Larix principis‐rupprechtii plantation could improve its water conservation .
