城市湿地研究进展

In this paper, the definition of urban wetlands was given based on analyses of the existence and connotation of urban wetlands. Urban wetlands are defined as those kinds of natural and artificial wetlands that distribute in urban areas and compose the ecoenvironmental foundation of cities. Chief directions and advances of urban wetlands studies at home and abroad were summarized, the differences of urban wetlands studies between China and other countries were analyzed, the main domains and existing problems of urban wetlands studies were pointed out, and the subject frame of urban wetlands science was constructed primarily. A basic definition of urban wetlands science was proposed in this paper as the science which studies the distribution, type, function, evoluation and management of urban wetlands. The studies would have positive significance to the development of wetland science.
