日本在经历了20世纪50年代和60年代的严重污染事件后,强化了环境政策.在水污染控制法中从严制定了污水排放限制和水质标准.在20世纪70年代和80年代成功地减少了污染.对"日本湖泊水质保全特别措施法"的现状、流域的点源和非点源污染负荷的削减、湖泊底泥的疏浚以及采用生态工程方法减少支流负荷等流域综合管理进行了综述和探讨,并给出了进一步改善湖泊水质的建议.

Lakes and marshes are valuable water resources and natural environments for human beings and it is necessary to preserve and improve their water quality. Since experiencing severe pollution problems during the 1950s and 1960s, Japan has been strengthening its environmental policies. Regulations on the quality of water were enforced under the Water Pollution Control Law, resulting in the successful reduction of pollutants during the 1970s and 1980s. In this paper, the present status of the special measures for conserving the water quality in lakes in Japan, and the measures for reducing influent loads from point and non-point sources, dredging of the sediment contamination on the lake bottom and water purification by means of vegetation, wetland, restoration of the lake's original landscape and integrated watershed management etc. are discussed. The proposal for future lake water quality management was also summarized.
