摘　　要：竹林具有重要的水源涵养功能,为科学认识毛竹林的水源涵养能力、充分发挥竹林在西毛里湖的水源涵养功能,利用综合蓄水能力法研究了西毛里湖湖滨毛竹林的水源涵养能力及其服务价值。结果表明:毛竹林生态系统每年水源涵养量为3353.97 m^3/hm^2,其服务价值为2247.16元/hm^2。其中,林冠层、灌草层、枯枝落叶层和土壤层的水源涵养服务价值分别为1082.05、0.51、11.66和1152.94元/hm^2,分别约占生态系统水源涵养服务价值的48.15%、0.02%、0.52%和51.31%。林冠层水源涵养能力仅次于土壤层,在生态系统水源涵养价值评估中不宜忽视。Bamboo forest has the important function of water conservation.In order to better understand the water conservation capacity of moso forest and give full play to the water conservation function of moso forest in West Mauri Lake,the paper studies the water conservation capacity and its value of moso forest there using the method of comprehensive water storage capacity.The results show that the annual amount of water conserved per hectare of moso forest is 3353.97 m^3,and its annual value per hectare was 2247.16 CNY.The annual value of water conservation service of forest canopy,understory,litter and soil layers and soil is 1082.05,0.51,11.66 and 1152.94 CNY/hm^2,accounting for 48.15%,0.02%,0.52%and 51.31%of the total value of water conservation,respectively.The water conservation capacity of forest canopy is only next to that of soil layer,which should not be ignored in the assessment of the water conservation value.
