纳帕海湿地生态系统功能与服务价值评估研究

A Research of Ecosystem Function and Services Valuation of Napahai Wetland

在对纳帕海湿地概况及退化动因进行解析的基础上,系统介绍了纳帕海湿地生态系统功能,定量评价了1981～2001年纳帕海湿地生态系统服务价值的变化情况。研究结果显示:1981年,纳帕海湿地生态系统服务价值总量为15.64亿元,2001年降低至1.33亿元。20a来,纳帕海湿地生态系统服务价值总量下降了91.5%。其中,下降幅度最大的为废物处理功能29%,其次为气候调节27.3%,第三为水源涵养24.7%,原材料下降幅度最小0.1%。鉴于此,为了保护纳帕海湿地资源,实现其可持续发展,应加强认识,适度控制旅游规模;严格执法,不断完善湿地保护体制机制;科学管理,引导湿地资源的合理利用。

After the brief introduction and analysis of Napahai Wetland and its degradation drivers, this paper systematically expounds its ecosystem function, and gives a quantitative system services from 1981 to 2001. It shows that the value of the evaluation about the value change of its ecoecosystem services of Napahai Wetland has dropped from 1. 564 billion RMB in 1981 to 133 million RMB in 2001, with 91.5% of its total value being lost during the past 20 years. 29% of the capacity in waste treatment has been lost, its climate regulation has been reduced by 27.3% and the water conservation has been decreased by 24. 7%. However, the raw material presents the least value change with 0. 1%. In view of this, in order to effectively protect and develop Napahai Wetland to meet sustainable development, the awareness needs to be built up, the tourism development should he controlled at a proper scale. More strict enforcement is required with improvement of the management mechanism. The wetland resources need to be properly utilized based on the scientific management.
