骆马湖湿地生态服务功能价值评估研究

以骆马湖为研究对象,在文献资料分析的基础上,运用替代市场价值法、市场价值法、影子工程法、比例折算法对骆马湖湿地生态服务的物质生产功能、大气调节功能、蓄水功能、水分调节功能、生物栖息地功能、水质净化功能、休闲娱乐功能和科研文化功能的价值进行评估。研究结果表明,骆马湖湿地生态服务功能的总价值为17. 9亿元/a,其中蓄水功能价值最大,占全部服务功能价值总量的33. 74%,是骆马湖湿地生态服务的核心功能;水质净化功能的价值较低,只占全部服务功能总价值的0. 84%,体现出骆马湖生态的脆弱性。当地有关部门应重视对骆马湖湿地生态的保护,尤其在排污方面要严格控制。

Evaluation of values of ecosystem services in wetland of Luoma Lake

For the case study of Luoma Lake, based on the analysis of the data from literatures, the main values of the ecosystem services in the wetland of Luoma Lake are evaluated by using the methods of the alternative market value, market value, shadow engineering and proportional conversion, which includes the ecological functions of material production, atmosphere regulation, water storage, water adjustment, water quality purification, habitats, leisure and entertainment and scientific researches. The results show that the total values of ecological services of the wetland in Luoma Lake are 1. 79 billion Yuan per year, and those of the water storage function are the largest and are 33. 74% of the total values, which is the core of the ecological services in the wetland of Luoma Lake. However, the values of the water purification function are the lowest, accounting for only 0. 84% of the total values, which reflects the vulnerability of the ecosystem in Luoma Lake. The local authorities should attach importance to the protection of wetland ecosystem in Luoma Lake, especially the strict control of sewage discharge.
