湿地生态系统服务功能及价值评估

生态系统服务功能是指生态系统与生态过程所形成及所维持的人类赖以生存的自然环境条件与效用。湿地生态服务功能不仅包括大量物质资源，而且具有巨大的环境调节功能和环境效益，在调节气候、控制土壤侵蚀，均化洪水，降解污染物、美化环境等方面发挥着重要作用。同时，湿地还是一个丰富的遗传基因库，特别是珍稀濒危物种的存续具有难以估量的重要价值。近年来生态系统服务功能已引起了人们的广泛重视，现已成为当前生态学与生态经济学研究的前沿课题。系统地分析了湿地生态系统服务功能及评价方法，并探讨生态服务功能淤其可持续发展研究的关系。

The Wetland Ecosystem Service Function and Value Estimation

The ecosystem service function refers to the natural environment condition and effectiveness, which are formed by ecosystem and eco-process, on which the human beings rely for existence. It consists not only large quantity of natural resources but also the great environmental regulating function and environmental profits. It can regulate the climate ,control soil erosion and flood ,decrease the pollutants and is also plays an important role in beautifying the environment. Furthermore, the wetland is also a rich gene bank,and it has immeasurable values ,especially for the existence of the disappearing species. In recent years, the ecosystem service function has caused vast concern and it has become the hot question of study. It systematically analyses the wetland service function and the evaluation method, and it also probes into the relationship between the ecosystem service function and sustainable development.
