Abstract:

Taking the West Route of the South to North Water Diversion Project as the background，based on the optimization of water-land relationship， aim at coordinating human-land relationship， Be directed against “changing low water and high ground to high water， low ground for remolding” and “high water consumption and diversion of Taohe River to east are proposed” use schemes： And in terms of ecological safety， food security， clean energy， and steady development of social economy， the eco-economic and social effects of the water use scheme are analyzed. Under this scheme， the cooperation between Yellow River natural channels and artificial artesian channels can improve the water-land relationship of middle and upper reaches of the Yellow River. Then over 100 000 square kilometers of eco-economic functional area integrated with landscape， forest， farmland， lake， grass， sand and ice will appear in a barren area locating at the intersection of Gansu， Qinghai， Ningxia and Inner Mongolia. It can provide water resources support to further consolidate the ecological safety barrier in northwest， ensure the national food security， promote the development and utilization of clean energy， steady development of regional social economy， and plays a role in strengthening the bones and waist in the Silk Road Economic Belt.

Key words: west route of the south-to-north water transfer, eco-economic and social effects, water-ecological-economic corridor
