摘要
城市的不断发展使不少城市湿地出现退化,表现为水污染严重、生物多样性下降、湿地面积萎缩等问题,使其原有的生态功能逐渐丧失。文章分析了城市湿地生态恢复亟待解决的问题,提出对退化的城市湿地进行生态恢复需要从多方面着手:在生态恢复之前,要设定合理的生态恢复目标;然后制定完善的工程规划,进行截污、管网改造等;重新构建其生物多样性,使城市湿地生态系统具有稳定性;最后,还需合理地较少人类活动的干扰对生态系统的影响。
The continuous development of city degraded most of the wetland in urban areas, with the phenomena of severe aquatic pollution, decreasing biodiversity and shrinking area of wetland, which gradually undermined its original ecological function. The ecological restoration of wetland should be improved in several aspects. A reasonable target of ecological restoration should be set and a proper engineering plan should be make firstly. Then the biodiversity should be reconstructed to stabilize the ecosystem of the urban wetland. Lastly,the disturbance of ecosystem from human activity should be reasonably minimized.
