摘要
简要阐述了苏州河历史演变、水文特性和水环境变化过程,回顾了自1998年开始的苏州河环境综合整治一期、二期、三期工程及开展的相关科研工作,并利用干流历年水质变化过程分析了历次治理取得的成效。结果表明:一期整治工程对水质指标的改善效果较好,而二、三期工程影响不明显,但当郊区河道进一步治理后,干流水质得到进一步好转。最后,针对目前正开展的苏州河综合整治四期工程总体方案,指出更大范围、更加彻底的标本兼治苏州河支流水环境会提升苏州河干流水环境,但要恢复苏州河的"水清岸绿、鱼翔浅底"的生态功能,还需有漫长的过程,且需要上游的江苏省内河道同步治理。
This paper briefly describes the historical evolution, hydrological characteristics and water environment change process of Suzhou Creek, reviews the first, second, and third stages of Suzhou River environmental comprehensive treatment project since 1998 and the related scientific research work, and analyzes the achievements of the previous treatment by using the water quality change process of the main stream over years. The results show that the improvement of water quality index is better in the first stage, but the influence of the second and third stages is not obvious. But when the suburban river is further improved, the water quality of the main stream is further improved. Finally, in view of the overall plan of the fourth stage of Suzhou Creek comprehensive treatment project, it is pointed out that a wider and more thorough treatment of the water environment of branchs of Suzhou Creek will improve the water environment of the main stream. However, to restore the ecological function of Suzhou Creek, which is "clear water, green bank, and fish swimming in rivers", it needs a long process, and the upstream in Jiangsu Province needs to be controlled simultaneously.
