The ec- ological and social benefits can be fully exploited provided ecological design be tak- en into consideration in urban wetland park planning. Landscape design plays a key role in urban wetland parks. Therefore, it is necessary to rationally distribute land- scape elements and further improve landscape design from quantity and type of the elements on basis of theories in order to provide references for urban wetland park design.展开更多
