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.
