摘要
对浙江省桐庐县生态公益林中主要森林类型的水源涵养功能进行评价。选取林冠截留率、枯落物层蓄积量、枯落物层最大持水率、土壤稳渗速率、土层厚度、土壤总孔隙度和非毛管孔隙度为评价指标,构建森林水源涵养功能综合评价方法。结合实测数据,对研究区各森林类型水源涵养功能进行评价。结果表明:水源涵养功能为青冈林>杉木林>毛竹林>香樟林>马尾松林>板栗林;青冈林的水源涵养功能属较好等级,杉木林、毛竹林、香樟林为中等,马尾松林、板栗林较差。
Water conservation function of main stand types of ecological protection forest in Tonglu county of Zhejiang province were evaluated.Rate of canopy interception,litter volume,maximal water holding rate of litter layer,soil steady infiltration,soil thickness,soil general porosity and non-capillary porosity were selected as evaluation index,and comprehensive evaluation method of water conservation function was used.The result show that the desending order of water conservation function was Cyclobalanopsis glauca,Cunninghamia Lanceolata,Phyllostachys heterocycla,Cinnamomum camphora,Pinus massoniana,Castanea mollissima;the water conservation function of Cyclobalanopsis glauca belongs to better grade,Cunninghamia Lanceolata,Phyllostachys heterocycla and Cinnamomum camphora were middle,Pinus massoniana and Castanea mollissima were worse.
