南水北调是从水量丰沛的长江流域向缺水的北方输水的跨流域调水工程,其中线是从长江中游,首先是从汉江丹江口水库引水。它的战略目标是与东线调水互相配合,共同解决华北黄淮海平原水资源短缺问题。按中线引汉总体规划,输水干线沿伏牛山山前地带经郑州西北的牛口峪过黄河。黄河以北研究了两种方案,其高线方案沿太行山麓在京广线西侧直达北京;其低线方案, The South-to-North Water Diversion Project is an inter-basin water transfer project that transports water from the abundant Yangtze River basin to the north with water shortage. The middle line is from the middle reaches of the Yangtze River and the first is from the Danjiangkou Reservoir in Hanjiang River. Its strategic goal is to coordinate with the eastern water transfer to jointly solve the water shortage problem in Huang-Huai-Hai Plain in North China. According to the midline of the Han Chinese master plan, water main line along the Funiu Mountain foreland through the mouth of the northwest of Zhengzhou Yellow River. Two schemes have been studied to the north of the Yellow River. The high-altitude scheme runs directly to Beijing on the west side of the Beijing-Guangzhou line along the foot of the Taihang Mountains. Its low-
