Technical And Economic Analysis Of Inter-basins Water Transfer

Water resources are the basic natural resources, the Department of Ecology and Environment, the controlling factor. China's water resources per capita is low, large variability in spatial and temporal distribution of water resources and land resources in the spatial distribution of the match situation is not ideal, the relative fragility of the ecosystem. With the economic and social development, China's land and water resources distribution and national industrial layout incompatible with the contradiction between the increasingly prominent in a number of shortage of water resources and population concentration, economic development, growing region, in order to solve the contradiction between water shortage and put forward the outer water transfer requirements. In this paper, the existing water transfer project by summarizing the experiences and lessons, summarized the key technology inter-basin water transfer issues, and one by one from the theoretical methods and practical applications of them are discussed. Papers dialectical analysis of the relationship between water diversion and ecological environment that the fundamental starting point of diversion and purpose is to resolve or alleviate the water shortage in regional competition conflicts to ecological and water damage to the environment; apply water three times a balance between supply and demand analysis, Analysis of regional water shortage situation, water for the dry regions of the characteristics of a competitive research inter-basin water diversion outside the rational allocation of water diversion and the local methods, guidelines and means.Based on the above key technical issues sorted out and resolved, papers in order to inter-basin water transfer project planning stage for time-section to plan the contents of the working platform to the urgency of inter-basin water transfer the necessity, feasibility, reasonableness of the argument as the key link, Expand inter-basin water transfer of economic, social, resources, and environmental aspects of the quantitative analysis. Papers in Shandong Province, the Yellow River water diversion project Weishan Gate, for example, the key line of the project planning are analyzed, analysis of the regional economic and social development and water resources development and utilization of the existing problems of water supply and demand contradiction solving Ways and comprehensive measures that the water diversion project on economic development, social stability and improve the environment, maintenance of ecosystem health is necessary, but should be based on the construction of water transfer project as the construction of water-saving and pollution prevention society the opportunity and impetus only two mutually exclusive, complement each other, can only achieve the purpose of diverting water, that protect the ecology and environment, promote sustainable development.
