摘要:In many arid and semiarid regions, water scarcity, population increase and frequent droughts are exerting great pressures on water resources. Presently, the Mid-route of the South-to-North Water Transfer Project (MRSN) was built to mitigate the water crisis in the north of China by long-distance transfer of water from the Yangtze River in southern China. This study investigated the running condition of the MRSN, including operation management, freezing situation and water quality. Water samples were also taken from different sites and then analyzed in laboratory. Results suggest that the project was reasonably designed and the project management was excellent. Closed management was adopted in the project to protect water quality. The sediment concentrations and water turbidities of the water samples were in the range of 0.2-0.8 kg/m(3) and 0.8-1.7 NTU, respectively, which met or were close to the standards of drinking water in China. Water freezing is also not a problem, since the thickest ice was only 0.9 cm even in the coldest season as the authors measured the investigation, and at the same time, the ice booms worked well. In the future, it is promising that to effectively integrate the methods of self-rescuing and water importing could fundamentally conquer water shortage, reasonably allocate water resources and finally achieve the harmonious development of economics, ecology and society.
