Abstract:

The project of water diversion from the Yangtze River to the Han River is a compensation project of SouthtoNorth Water Transfer Middle Line Project.According to the master plan，its construction should comply with the local planning for water resources development，and should not be designed as enclosed “specus” adding supplemental water to the lower reaches of the Han River.Abiding by the thought on saving resources，protecting the environment，promoting development，it is suggested that the project of water diversion from the Yangtze River to the Han River should take the project of transferring the water from the Yangtze River to north in Jiangsu Province as a model，to expand the project to supply both the Han River and the Yellow River，so as to substitute Phases II of SouthtoNorth Water Diversion Middle Line Project. ①Divert the water from the Yangtze River to Chang Lake by making use of the water course of the Zhuzhang River lower reaches to convey water.In the mean time，rehabilitate Jingzhou City river system，remove three environmental risks as 〖WTBX〗Bilharziasis〖WTBZ〗 spreading and diffusing，the silt entering the lake and the water contamination；②The project of diverting water from the Yangtze River to Han River lifts the water to Xinglong Reservoir by making use of the storage of the Chang Lake，so as to economizing the channel length.③Nianpanshan stagedevelopment adopts onelevel and twostations pumping water storage way to simplify opposite direction water conveyance in the Han River main stream.Pump water to Chuijiayin Reservoir to improve water quality of the lower reaches of the river and increase water resource for the Yellow River lower reaches as the stable and reliable water source. ④The Eryu Channel will be build on east side of the Tang River，in the Nanyangxiangyang lower land pass，to transfer water to Fangcheng and Zhengzhou in stead of to Danjiangkou Reservoir to supply the Yellow River so as to build a water carriage system from north to south.

Key words: water diversion from the Yangtze River to the Han River, diverting clean water operation, Eryu channel, transferring water from the Yangtze River to north to supplement water in the Yellow River
