基于东汶河城区段生态修复工程的湿地设计探讨

Discussion on wetland design in ecological restoration project based on Dongwen River urban section

本文以东汶河城区段生态修复工程为例,结合城市河道治理对该地区的湿地水生态修复工程进行了设计,采用雨污分流、河底清淤,软质河底、地形泡、滚水堰以及河心岛的构建方法,达到了控制水位、控制流速、促进微生物和植物生长的目的,改善了湿地水质较差的问题,完善了湿地生物系统,丰富了食物链层级,解决了湿地生态系统的良性循环问题。可为类似生态修复工程提供参考。

Taking the ecological restoration project of Dongwen River as an example,the design of wetland water ecological restoration project in this area was carried out in combination with urban river regulation. The construction methods of rain and sewage diversion,river bottom desilting,soft river bottom,topographic bubble,rolling weir and river core island were adopted,which achieved the purposes of controlling water level, controlling flow rate, promoting the growth of microorganisms and plants,improving the problem of poor wetland water quality,perfecting wetland biological system,enriching food chain level and solving the problem of benign circulation of wetland ecological system It can provide reference for similar ecological restoration projects.
