洪泽湖和高邮湖是大运河和南水北调东线工程的水源。随着南水北调中线工程建设步伐的加快和南水北调中线工程申报世界遗产的倡议，南水北调中线工程的水质和管理问题日益受到关注。通过对高邮湖和洪泽湖的水样、监测数据和表层沉积物中重金属元素含量的分析，对高邮湖和洪泽湖的水质进行了评价。根据2003年的水样分析，重金属含量满足洪泽湖和高邮湖的水质要求。但2004年的监测数据表明，洪泽湖和高邮湖的水质均为劣Ⅲ类，达不到规定的标准。沉积物样品中的重金属元素也超过了可接受的环境标准。启动了一些项目，通过控制废水排放，标准化船只类型和制定保护湖泊的法规来改善湖泊环境。然而，该地区目前的管理体制仍然存在纵向和横向分散以及公众参与不足的问题。针对湖泊面临的问题，探讨了水资源综合管理是解决问题的有效途径。
Hongze Lake and Gaoyou Lake are the source of water for the Grand Canal and the eastern route of the South-to-North Water Transfer (SNWT) project. With the accelerating pace of construction of the SNWT and the initiative to achieve "World Heritage " status for the canal, the water quality and management of the lakes have gained attention in China. Based on analysis of water samples, monitoring data, and the content of heavy metal elements in surface sediments, the water quality of Gaoyou Lake and Hongze Lake have been examined. According to the analysis of the water samples taken in 2003, the content of the heavy metals met the water demands for Hongze Lake and Gaoyou Lake. However, monitoring data of 2004 indicate that the water quality of Hongze Lake and Gaoyou Lake both were worse than grade III which cannot meet the required standard. The heavy metal elements of sediment samples also were above the acceptable environmental standard values. Some projects were launched to promote the lake environment by controlling wastewater emissions, standardizing the types of boats and introducing regulations to protect the lakes. However, problems of vertical and horizontal fragmentation and insufficient public participation in the current management system still exist in the area. Considering the problems confronting the lakes, Integrated Water Resource Management is discussed as an effective approach to overcome the problems.
