Research Of Water Resources Ensure System Of Main Diversion Area Of Nenjiang River In Songnei Plain

Due to the complexity involved such aspects of nature, engineering, economy, society and environment, the researches of Ensure System of water resources sometimes can not reach the anticipations if some techniques are simply used. So how to builid Ensure System of water resources is an important subject concerned by schoolors and engineers of inside and outside home. In this paper the Ensure System of water resources is researched through the aspects of present utilization situations of water resources, the water resources need of GDP, the analysis of water supply amount and so on. The rational engineering scale is ascertained on the base of the first time balance analysis of water need and supply and the primary management pattern and construction and management system of the project are put forward.At first, in this paper, the water need of different departments in program level year are analyzed and calculated according the requires of GDP in research areas. In the same time, according the principal of firstly using the water supplied by the project in surface and considering the limitation of the ground water, retreatment water and water returned from agriculture, the amount of water supply is analyzed. On the basis of this the first time balance analysis of water need and supply is made.According the results of the first time balance analysis of water need and supply and considering the different schemes of water supply, research of the scale of diversion project is made and the scale is ascertained rationally.Then the disadvantages of the present project management system are analyzed and according the main considerations of "government macroeconomic control .main operation by market rules, modern enterprise management, participation of water user" the researches of construction and management systems is made and the primary management patterns in the periods of construction and operation are put forward.At last, the series of analysis and caculations prove that the main-body project of Diversion Porject from Nenjiang River shuold be constructed earlier to realize the sustainable utilazation of water resources to support the sustainable developments of economy and society.
