摘　　要：通过对临安市水涛庄水库集水区森林地表土壤和林下枯落物的取样分析,分别对11种森林类型的枯落物层和土壤层的水源涵养特性进行研究,从而得到该区域森林枯落物及土壤的水源涵养功能值。研究结果表明:研究区枯落物水源涵养总量为9.17×10~4m^3,单位面积水源涵养量为17.10 m^3/hm^2,单位面积持水拦截量表现为马尾松-白栎-短柄枹栎混交林>青冈栎林>麻栎林>短柄枹栎林>山核桃林>灌木林>毛竹林>金钱松林>马尾松林>高节竹林>杉木林;土壤水源涵养总量为2108.41×10~4m^3,单位面积水源涵养量为3931.06 m^3/hm^2,单位面积持水量表现为马尾松-白栎-短柄枹栎混交林>青冈栎林>毛竹林>麻栎林>短柄枹栎林>金钱松林>高节竹林>马尾松林>杉木林>灌木林>山核桃林。This research mainly studied the water conservation function of litter layer and soil layer in Shuitaozhuang reservoir water collecting areas which was located in Lin’an city, and compared the water conservation function between 11 kinds of forest types. In this study, we samplinged litter and soil of different forests and tested water storage capacity of each sample in the lab. The results showed that the water conservation amount of litter layer in study area was 9.17×104 m3 and the water conservation capacity per unit area of litter layer was 17.10 m3/hm2. The water conservation amount of soil layer in study area was 2108.41×104 m3 and the water conservation capacity per unit area of soil layer was 3931.06 m3/hm2. In terms of water conservation capacity per unit area, the litter layer of different forest types espressed that Pinus massoniana-Quercus fabri-Quercus fabri mixed forest>Cyclobalanopsis glauca forest>Cyclobalanopsis glauca forest> Quercus serrata var. brevipetiolata forest>Carya cathayensis forest>Shurb forest>Phyllostachys heterocycla forest>Pseudolarix amabilis forest>Pinus massoniana forest>Phyllostachys prominens forest>Cunninghamia lanceolata forest, while the soil layer espressed Pinus massoniana-Quercus fabri-Quercus fabri mixed forest>Cyclobalanopsis glauca forest>Phyllostachys heterocycla forest>Cyclobalanopsis glauca forest>Quercus serrata var.brevipetiolata forest>Pseudolarix amabilis forest>Phyllostachys prominens forest>Pinus massoniana forest>Cunninghamia lanceolata forest>Shurb forest>Carya cathayensis fores.
