摘　　要：在实地调查和试验的基础上,依据资源经济学和生态经济学的理论和方法,针对洞庭湖湿地资源的特点,对洞庭湖湿地的生态服务功能价值———直接利用价值和间接利用价值进行了货币化评估,由此得出洞庭湖湿地的生态服务功能价值为80.72亿元;其中调蓄洪水的价值为37.12亿元,占45.99%;研究结果表明,洞庭湖湿地生态服务功能价值主要表现在调蓄洪水、供水和调节气候等方面的价值。因此,只有合理开发洞庭湖湿地资源,保护好洞庭湖区湿地生态环境,才能实现洞庭湖区湿地资源的可持续利用,保证湖区经济的可持续发展。Wetland is featured by its unique ecological services function and economical value .It is one of the most productive ecosystem which it has a huge economical and socio-ecological benefits in earth, such as food supply, raw and processed materials, water resources, flood control and drought defying, protection biodiversity and tourism etc. The Dongting lake wetland is one of the largest lacustrine wetland eco-system in China. There are very plentiful wetland resources. It includes 1428 species of plants resources, 216 species of birds resources, 119 species of fish resources, 27 species of amphibians and retile, 22 species of mammals and a great many of other wild living things. Based on the wetland resources' character, the economics theory and method is applied in the paper on the base of the investigation and experiment to analyses the asset value type of the wetland resources and to evaluate the direct values in use and the indirect values in use in Dongting lake wetland resources such as the method of tax rate of Sweden.Researching value, travel consumption method, Robert Constanza method, market value method, assets value method. The conclusion can be drawn that the total assets value of the wetland resources is 80.72×108元RMB in Dongting lake wetland. The value of flood control is 37.12×108元RMB, It is 45.99percent of the total value. The result shows the wetland ecosystem service valuation is the main part of the wetland resource assets, and that only when we make use of the wetland resources rationally and protect the wetland eco-environment and carry out the assets management of the wetland resources in Dongting lake area, can the sustainable utilization of the wetland resources be realized and the sustainable development of the regional economy around Dongting lake area is guaranteed.
