- 摘要：北运河是北京市重要的绿色生态走廊，贯穿联络京津冀协同发展多个关键节点.北运河主要由来自于城市污水处理厂排水等非常规水源补给，其水环境治理和水生态修复不仅是支撑京津冀生态文明建设的核心，而且是支撑北京城市副中心等重点区域水生态环境改善的重要环节.本专刊是国家水专项"北运河项目"团队近年来科研成果的总结，从"源-流-汇"全过程污染防控的角度出发，在"源削减"-多源污染防控、"流改善"-河流水质改善与生态修复、"汇景观"-库区水质改善与生态修复三个方面对研究和实践进行了梳理总结，以期为北运河流域绿色生态廊道构建提供科技支撑.
- Abstract：As the key ecological corridor in Beijing, the North Canal River crosses through megacity areas of Beijing-Tianjin-Hebei region. The North Canal River is mainly replenished with reclaimed water from municipal wastewater treatment plants, and its water environment treatment and aquatic ecological restoration are not only the core of supporting the construction of ecological civilization in the coordinated development of the Beijing-Tianjin-Hebei Region, but also the important link of supporting the improvement of water environment & ecological restoration in key areas such as city subcenter of Beijing. Therefore this special issue is a summary of the scientific research outputs of the "North Canal River Project" in recent years. From the perspective of water pollution control and prevention for the "Source-Flow-Sink" whole process, this special issue summarizes the research and practice in three aspects as following: "Source Reduction"- Multi-source pollution prevention and control, "Flow Improvement" - River water quality improvement and ecological restoration, "Sink Landscape" - Reservoir water quality improvement and ecological restoration, so as to provide scientific and technological support for the ecological corridor construction of the North Canal River watershed.
