摘要：

根据截留法估算湟水河流域水源涵养量,并利用影子工程法、支付意愿法对水源涵养林的涵养总量、经济效益进行了评估。结果表明:在不同的林分类型中,土壤单位面积蓄水量大小顺序为:云杉>青杨>桦树>落叶松>灌木;林下枯枝落物层单位面积蓄水量大小顺序为:青杨>云杉>落叶松>桦树>灌木,总体来看,云杉和青杨涵养水分能力较好。流域水源涵养林调节水量为0.22亿t,根据单位库容造价计算其经济价值0.60亿元,根据平均居民用水价格计算其净化水质价值0.47亿元。

摘要：

Water conservation mass was studied by using interception method and the economic effect of water conservation forest was assessed by shadow engineering method and Contingent valuation method.The results showed that in different stand types,soil water storage capacity per unit area was sequenced as Picea asperata,Cathay Poplar,Betula,Tamarack and Bushes from high to low.Water holding of little per unit area was ranked as Cathay Poplar,Picea asperata,Tamarack,Betula and Bushes from high to low.Overall,water-storage fluctuation of Picea asperata and Cathay Poplar was better.The water conservation mass of water conservation forest in Huangshui River was 22 million tons.The economic value was 60 million Yuan by per cost of storage capacity and the water purification value was 47 million Yuan by price of per household water consumption.
