Abstract 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.
