Abstract:

As a special ecosystem in the city, urban wetlands play an important part both in ecological 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 development 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 resulted in wetland resources decrease, degradation of wetland function, serious pollution and other eco- 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 ecological 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 outlined. Finally, the strategies for urban wetland protection in China were put forward, and some important 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.
