湿地是位于水域和陆地之间的生态交错区,可以控制水域对陆地的侵蚀,对化学物质具有高效的处理与净化能力,还能够提供滨海咸水、河口或淡水栖息地。湿地是一道天然屏障,也是多种生物的避风港。城市湿地是指位于城市规划区内符合《湿地公约》定义的各类湿地,它是人工湿地、半人工湿地和天然湿地的复合体。城市湿地公园的营建,便是为了更有效地保护和恢复城市湿地资源,将城市湿地保护与景观建设相结合,为广大市民提供亲近自然的场所,有助于丰富城市园林系统
Wetlands are ecotones between waters and land that control the erosion of land by water, efficient treatment and purification of chemicals, and coastal saltwater, estuarine or freshwater habitats. Wetlands are a natural barrier and a haven for many creatures. Urban wetlands refer to all types of wetlands within the urban planning area as defined by the Convention on Wetlands. They are constructed wetlands, semi-constructed wetlands and natural wetlands. The construction of the urban wetland park is to protect and restore the urban wetland resources more effectively and to combine the protection of urban wetlands with the landscape construction so as to provide the general public with places close to nature and contribute to the enrichment of the urban garden system
