| 摘 要： | 对五台山地区门限石林场南梁沟5种林分枯落物蓄积量及持水量与土壤容重及孔隙度进行测定，研究5种林分类型的水源涵养功能。结果表明，5种林分类型的枯落物平均蓄积量为29．7t／hm^2；枯落物平均最大持水率为201．2％；5种林分类型的土壤容重均小于对照荒草坡；总孔隙度、毛管孔隙度、非毛管孔隙度均大于对照荒草坡；林地土壤暂时贮水量与涵养水源总量均大于对照荒坡。由此可知，针阔混交林对林地土壤改良效果及涵养水源功能均优于人工林与灌木林，营造水源涵养林时，可以考虑优先营造针阔混交林。

| Abstract: | Forest litter stock, water-holding capacity, soil bulk density and porosity of 5 kinds of forest in field were inves- tigated in Nanliang channel of Menxianshi forestry centre in Wutai mountain region, and water conservation function of five forests was researched. Average forest litter stock of 5 kinds of forest was 29. 7 t/hm^2 ; the biggest water-holding rate of lit- ter was 201.2% ; soil bulk density of five forests were less than that of the slope ; total porosity, capillary porosity, noncap- illary porosity were larger than that of the slope; soil pondage temporarily and water conservation were larger than that of the slope. Above all, soil improvement and water conservation function of mixed broadleaf-conifer forest were superior to plan- tation and bushes, so it should be considered firstly in water conservation afforestation. |
