根据资源经济学和生态经济学理论,运用市场价值、影子工程和碳税法等方法对千岛湖湿地生态系统的物质生产、环境调节和文化社会等功能的直接和间接价值进行货币化评估。结果表明：千岛湖湿地生态系统具有巨大和多重服务功能价值,总价值为170.86×108元.a-1,其中,生态环境调节与维护功能价值最大,占总服务价值的89.10%,其次是物质生产与供给功能价值,占8.28%,文化社会功能价值最小,占2.62%;通过对10项子功能进行评估得出,涵养水源功能价值最大,占总价值41.19%,其次为调蓄洪水功能价值,占30.64%,第三是固碳释氧功能价值,占15.07%,第四是供水功能价值,占6.64%,旅游休闲、渔业生产和发电价值占3.19%,降解污染、科研教育和维护生物多样性价值占3.27%。
根據資源經濟學和生態經濟學理論,運用市場價值、影子工程和碳稅法等方法對韆島湖濕地生態繫統的物質生產、環境調節和文化社會等功能的直接和間接價值進行貨幣化評估。結果錶明：韆島湖濕地生態繫統具有巨大和多重服務功能價值,總價值為170.86×108元.a-1,其中,生態環境調節與維護功能價值最大,佔總服務價值的89.10%,其次是物質生產與供給功能價值,佔8.28%,文化社會功能價值最小,佔2.62%;通過對10項子功能進行評估得齣,涵養水源功能價值最大,佔總價值41.19%,其次為調蓄洪水功能價值,佔30.64%,第三是固碳釋氧功能價值,佔15.07%,第四是供水功能價值,佔6.64%,旅遊休閒、漁業生產和髮電價值佔3.19%,降解汙染、科研教育和維護生物多樣性價值佔3.27%。

According to the resource economics and ecological economics theory,through using market value,shadow engineering as well as carbon tax and other methods,direct ＆ indirect values of function for organic matter,environment regulation and cultural-social and other functions in the ecosystem of Thousand-Island Lake wetland were conducted monetary evaluation.Result shows that the Thousand-Island Lake wetland,whose total value is 170.86×108 Yuan per year,possesses huge and multiple ecological services value;value of function for eco-environmental regulation ＆ maintenance which is the greatest,constitute 89.10% of the total value.The second is the value of function for material production ＆ supply,constitute 8.28% of the total value.The value of function for cultural-social are the least,accounted for 2.62% of the total value.The result of evaluation of 10 subfunctions shows that the most important function is water conservation which constitute 41.19% of the total value.The second is value of function for flood storage,accounted for 30.64% of the total value;the third is the value of function for carbon fixation ＆ oxygen release,accounted for 15.07% of the total value.The fourth is the value of function for water supply,accounted for 6.64% of the total value.Value of leisure travel,fishery production ＆ generate electricity constitute 3.19% of the total value.Value of degradation of pollution,research education ＆ maintenance of biological diversity constitute 3.27% of the total value.
