摘要：2002年，中国在完成了历时50年的可行性研究后启动了南水北调工程。到2050年，东、中、西三线工程将可从水资源丰富的长江流域向干旱的北方调水448亿立方米/年，缓解水资源短缺问题，促进全国社会经济均衡发展。但如此大的引水量，由于年流量的变化，可能会深刻改变黄河上游、长江支流汉江下游以及中线工程供水区的河流环境。华北平原受水区的次生盐碱化似乎是不可避免的，长江流量的减少将导致海水入侵长江三角洲。本文介绍了该项目并讨论了其对环境的影响。此外，还提出了中国生态研究网络下的环境监测长期监测策略。
Abstract: In 2002, China launched the South‐to‐North Water Transfer Project after completing a 50‐year feasibility study. By 2050, the three‐route (i.e., East, Middle, and West) project will be capable of transferring 44.8 billion m3/year of water from the water rich Yangtze River to the arid north to alleviate water shortage and help secure a balanced social and economic development across the nation. However, diversion of such a large quantity of water could profoundly change the riverine environment of the upper Yellow River and the lower reach of the Han River, a tributary of the Yangtze River and the water supplying area of the project’s Middle Route, because of changes in the annual discharge. Secondary salinization seems inevitable in the water receiving areas of the North China Plain, and decrease in the discharge of the Yangtze River will result in seawater intrusion into the Yangtze Delta. This paper describes the project and discusses its environmental implications. Additionally, a long‐term monitoring strategy under the umbrella of the Chinese Ecological Research Network is proposed for environmental monitoring.
