摘　　要： 根据多次科考调查的成果和资料,对三江源区湿地生态系统的结构和功能进行了分析。结果表明:湿地生态系统服务价值为2.10×1011Yuan·a-1,占三江源区生态系统服务功能总价值的62.07%;其中废物处理、水源涵养、气候调节的价值较大,分别为6.40×1010Yuan·a-1、5.79×1010Yuan·a-1、4.90×1010Yuan·a-1,分别占湿地生态系统总价值的30.55%、27.61%、23.39%。其次为生物多样性保护、土壤形成与保护、气体调节、食物生产和原材料、娱乐文化等服务功能。此外针对三江源区湿地生态系统退化机制和存在的主要问题,提出了合理利用与保护对策。 The structure and function of wetland ecosystem in Sanjiangyuan region are analyzed based on investigation data. The results indicate that the value of wetlands ecosystem is 2.10×10^11 YuanRMB.a^-1 and is 62.07% of the total value of ecosystem of Sanjiangyuan region. The value of waste treatment, water conservation and climate regulation is 6.40×10^10 YuanRMB.a^-1, 5.79×10^10 YuanRMB.a^-1 and 4.90×10^10 YuanRMB.a^-1, respectively and accounts for 30.55%, 27.61% and 23.39% of the total value of wetlands ecosystem, respectively. There are some other services such as biological diversity, soil formation and erosion control, gas regulation, food and raw materials, recreation and culture, In addition, Measures on reasonable utilization and conservation are put forward on the basis of degradation mechanism and problem of wetlands ecosystem in Sanjiangyuan region.
