摘要
广州市海珠区位于珠江三角洲弱潮河口,针对其河网地区水流双向流容易造成回流,产生淤积现象,致使水流不畅,水质污染严重等问题,提出了水系连通方案:对断头河涌进行疏浚并相互打通,恢复其原有的引、排水功能,实现单向流动;恢复或新开挖河涌2处,连通河涌10处,总长8 210 m。河涌水系连通实施后,区内水环境得到了较大改善。
Haizhu District of Guangzhou City is located at the weak tidal estuary of Pearl River Delta where bidirec-tional flow in the river network frequently leads to backflow, deposition, poor flow and water pollution. A project of connecting the river network was proposed. The components include dredging and connecting the dead-end chan-nels to recover their diversion and drainage functions, change bidirectional flow into one-way flow; recovering or newly excavating 2 channels and connecting 10 channels. The total length amounts to 8210m. After this project was completed, the water environment in Haizhu District has been greatly improved.
