Abstract
Soil and water conservation function of main forest types of ecological protection forest in Kaihua county of Zhejiang province were evaluated. Rate of canopy interception,shrub-grass layer coverage,litter coverage,litter thickness,maximal water holding value of litter layer,soil steady infiltration,soil non capillary porosity and soil erodibility k were selected as evaluation index,and comprehensive evaluation method of water conservation function was used. The results show that the desending order of soil and water conservation function was coniferous-broadleaved mixed forest>Quercus acutissima>Phyllostachys heterocycla>Pinus massoniana>Cunninghamia lanceolata; the soil and water conservation function of coniferous-broadleaved mixed forest belongs to stronger grade,Phyllostachys heterocycla,Quercus acutissima,Cunninghamia lanceolata,Pinus massoniana were middle.
