According to the estimation method of environmental economics and ecological economics, the value of Daqing wetland which dominates the service function of the ecosystem system was quantified and the total value of the service function of the wetland ecosystem system was analyzed. It was found that he total value of the service function of the wetland ecosystem system was 63. 14×108 yuan, of which the function value of material production is 0. 81×108 yuan, that of air-component regulatory, that of water supply, that of water storage and flood regulation, and that of aesthetic value of tourism were 9. 20×108, 2. 92×108, 24. 45×108 and 7. 48×108 yuan, respectively. Besides, the function value of other features was worth 18. 28 x 10 yuan. The service function of natural wetland ecosystem was mainly represented in water storage, flood regulation, and water purification, whereas the service function of artificial wetland ecosystem was mainly represented in water storage, flood regulation, and water supply. Reservoirs and ditches are the main contributors. The value of the service function of natural wetland ecosystem is far greater than that of artificial wetland ecosystem, playing an important role in economic development.%根据环境经济学和生态经济学的估算方法,将大庆湿地主导生态系统服务功能的价值进行量化,对研究区湿地生态系统服务功能价值总量进行分析,得出研究区湿地生态系统服务功能价值总和为63.14亿元.其中,物质生产功能价值为0.81亿元,大气组分调节功能价值、供给水源功能价值、蓄水调洪功能价值和美学旅游功能价值分别为9.20、2.92、24.45和7.48亿元,其他功能价值为18.28亿元.自然湿地的生态系统服务功能主要体现在蓄水调洪功能和净化水质功能上,而人工湿地的生态服务功能主要体现在蓄水调洪和供给水源上,水库沟渠为其主要的贡献者.自然湿地的生态系统服务价值远远大于人工湿地,自然湿地对经济发展起着极为重要的作用.
