京杭运河常州段水环境保护成效评价及实施建议

分析了京杭运河常州段水环境存在的主要问题,并以水质监测数据为依据,评价了为保护运河水环境开展的优化产业格局、完善管网配套、实施清水工程、加强水质监控等措施的实际成效。监测结果表明,近年来运河水质明显改善,污染物浓度逐年降低;水生态环境趋好,生物完整性指数波动上升。在此基础上,进一步提出了深化京杭运河常州段水环境保护的实施建议。

Main water environmental problems of Beijing-Hangzhou Grand Canal at Changzhou section were ana- lyzed. According to the monitoring data of water quality, effects of protection measures on the canal water environ- ment, such as optimizing the industrial structure, developing the sewage pipe network, cleaning the river water engineering, strengthening the water quality monitoring were evaluated in recent years. The results showed that the water quality of the canal had improved markedly, and the concentration of pollutants had decreased year by year; the water ecological environment got better, and the biotic integrity index fluctuated upward. Based on the status, suggestions for deepening measures of protecting the water environment of the canal were proposed.
