摘　　要：根据浙江省缙云县117个公益林固定小班监测数据,在推算不同群落类型如松林、杉木林、阔叶林、针阔混交林、毛竹林和灌木林等生物量的基础上,估算了公益林植被涵养水源效益和固土保肥效益。结果表明:2000—2010年间缙云县公益林调蓄水量3.69×108 t,水源涵养效益累计21.16亿元。其中调水效益15.77亿元,净化水质效益5.39亿元。不同群落类型涵养水源能力依次为毛竹林>杉木林>阔叶林>松林>针阔混交林>灌木林;缙云公益林2000—2010年间固定土壤共0.12×108 t,减少流失的土壤养分纯氮9.18×103 t,纯磷2.57×103 t,纯钾2.47×105 t,有机质3.73×104 t,累计效益14.28亿元。不同群落类型固土保肥能力依次为阔叶林>针阔混交林>毛竹林>松林>杉木林>灌木林。The efficiencies of water,soil and fertilizer conservation of public welfare forests in Jinyun County,Zhejiang Province in 2000-2010 were evaluated based on monitoring data of 117 permanent sample plots by calculating the biomass of six types of forest communities.The results showed that the water-regulation and water-storage capacity of public welfare forest in Jinyun County was 3.69×108 t,cumulative water conservation efficiency was 2.116 billion yuan,in which efficiencies of water-regulation and water-storage were 1.577 and 0.539 billion yuan,respectively.Water conservation capacity of different forest communities decreased in the order showed as Phyllostachys pubescent forest Chinese fir forest broad-leaved forest Masson pine forest broad leaved mixed forestscrub forest.The soil conservation efficiency of public welfare forest was 0.12×108 t.Reduced nutrients loss amounts of N,P,K and organic matters were 9.18×103 t,2.57×103 t,2.47×105 t and 3.73×104 t respectively,and the cumulative economic efficiency was 1.428 billion yuan.Soil and fertilizer conservation capacities of different forest communities decreased in the order as broad-leaved forest broad leaved mixed forest Phyllostachys pubescent forest Masson pine forest Chinese fir forest scrub forest.
