苏州市外城河水生态环境状况及对策研究

Study on the ecological environment and countermeasures of the water in the outer city of Suzhou

本文调查了苏州市的水系统及其生态环境质量,收集了关于苏州市外城河生态环境的相关数据,可以得出苏州市外城河主要的污染物是有机物,尤其是在丰水期和枯水期比较更为严重。苏州市外城河水污染的特点主要是从点逐渐扩展到面的,但是由于苏州古城区的污水处理设施不当,缺乏对面源污染的处理,一些湿地遭到了破坏。针对以上,建议采取以截断污染流、防预结合、引水、疏浚通道等对策来对苏州市外城河水的生态质量进行进一步的改善。

Based on the investigation of the water system and its ecological environment quality in Suzhou and the collection of relevant data on the ecological environment of the outer city river in Suzhou,it can be concluded that the main pollutants of the outer city river in Suzhou are organic matters,especially in the wet season and the dry season.The characteristics of the river water pollution in the outer city of Suzhou are mainly from point to area.However,due to the improper sewage treatment facilities in the ancient city of Suzhou and the lack of treatment of the opposite source pollution,some wetlands have been damaged.In view of the above,it is suggested to further improve the ecological quality of the river water in the outer city of Suzhou by measures such as cutting off the pollution flow,combining prevention with pre-treatment,water diversion and dredging channels.
