城市湿地作为城市中一种特殊的生态系统，在生态环境和社会服务方面发挥着重要作用。城市湿地为城市的可持续发展提供重要的水资源和生态环境保护，湿地资源的合理开发利用是保证城市可持续发展的前提。然而，随着城市化的发展，城市湿地保护问题日益突出，城市湿地开发中的一些不合理行为导致湿地资源减少、功能退化、污染严重等生态环境问题。城市湿地的保护与合理利用越来越受到国际社会的重视。在人类活动的强烈干扰下，城市湿地生态功能恶化，富营养化严重，全球城市湿地面积呈减少趋势。从城市湿地功能出发，分析了城市湿地存在的主要问题。对湿地保护与恢复的相关技术进行了综合分析，并对国内外城市湿地研究进展进行了综述。最后指出了城市湿地保护与恢复的研究方向.最后，提出了中国城市湿地保护的对策，并对中国城市湿地研究与保护中的一些重要问题进行了讨论。这些研究对城市湿地科学乃至整个湿地科学的发展具有积极意义。
As a special ecosystem in the city, urban wetlands play an important part both in eco- logical environment and social services. Urban wetlands can offer the important water resources and ecological environment protection for a city’s sustainable development, and the rational de- velopment and use of wetland resources is a prerequisite to ensure the sustainable development of a city. However, with the development of urbanization, urban wetland protection has become an increasingly important issue, and some irrational behaviors in urban wetlands’ exploitation result- ed in wetland resources decrease, degradation of wetland function, serious pollution and other e- co-environmental problems. More and more attention has been paid to urban wetlands protection and their rational use of the international community. Under the intense human disturbance, the e- cological services deteriorated and eutrophication was serious, and the urban wetland area of the world is reducing. Thus, the main problems of urban wetlands were analyzed on the basis of urban wetland function. Moreover, the technologies related to wetlands protection and restoration were analyzed synthetically, and the progress of urban wetlands studies in the world were summarized. Furthermore, future research directions of urban wetland protection and restoration were also out- lined. Finally, the strategies for urban wetland protection in China were put forward, and some im- portant issues about the study and protection of China’s urban wetlands were discussed. The studies would be of positive significance to the development of urban wetland science and the whole wetland science.
