- Abstract:
- In view of water quality deterioration and aquatic ecosystem damage in small urban watersheds, taking the ecological restoration of water body in Ziwei cultural park, Weitang Town, Suzhou as a case, the technologies and measurements, such as pollution source control and interception, internal pollution source treatment, aquatic plant restoration, in-situ water quality purification and habitat adjustment, are adopted to comprehensively manage the water systems of Zhujiaxiang River, Beixuejing River, and Miaoqian River in the park. After the implementation of engineering measures, the water quality of Zhujiaxiang River was improved from inferior level Ⅴ to level Ⅲ in the Environmental Quality Standards for Surface Water (GB 3838-2002). The water quality of Beixuejing River and Miaoqian River were also improved from level Ⅴ to level Ⅳ. The aquatic ecosystem has been restored and the diversity of aquatic organisms has increased.
