摘　　要：通过对城市湿地功能和特征以及城市化进程中城市湿地面积缩减、水质污染及功能退化等问题的分析,揭示城市湿地退化的主要原因,依据结构决定功能的生态学原理,提出湿地退化恢复的实质是结构的修复,城市湿地的恢复应采取汇水区水源保护、汇水净化治理、入湖河流截污、河道修复及重建湖滨结构的城市湿地恢复策略。An analysis was conducted of wetland functions and characteristics, and shrinking of wetland areas during urbanization, as well as water pollution and functional degradation, the major causes for urban wetland degradation were revealed. According to the ecological principle that structure determines functions, it was suggested that reconstruction of wetland structure is the basis for restoration of degraded wetland. A strategy of urban wetland restoration should be taken with focuses on protection of water sources in catchment areas, purification of catchment water, pollutant interception/br rivers at the entrance to lakes, restoration of water ways and riparian structure reconstruction.
