Study On Optimal Allocation Of Water Resource In Guangzhou City Based On The Qulity And Quantity

Water is the material basis of human being's survial and social and economic development.it is important natural resource that can't be replaced.With economic and social developmet and with municipal process quickening,people have higher demand for water quantity and water quality .But fresh water that can be used is limited.So scarce water not only restricts economic and social deveopment but also results in continuous deterioration of water enviroment.So study on the optimal allocation of regional water quality and water quantity is important and has theoretical and practical meaning.In this paper, reseach situation of optimal allocation of water resources at home and at abroad is analyzed and the shortcomings of optimal allocation of water resouce at present are pointed out.On the basis of analyzing the structure of water system and its characteristic, describe the basic conception of rational distribution of water resource in detail more overally,theory and method. Then builded the water resource distribution model that the water quality and water quantity jointly disposes. And analysed the project of the rational distribution of resources of water by project measures,and analysed by project measures the project of the optimal allocation of resources of water at the same time.1.Explain the background of water resource distributed that the question puts forward rationally from all directions ,point out its research meaning .Carry on the survey domestic and international research history and current situation .Point out the subject matter existing at present .then study the direction clearly.2.Have introduced the basic state of Guangzhou city ,current situation of the water resource, and predicted the annual demand and supply of water resource scientificly ,and have carried on supply and demand analysis.3.Start with the basic conception of optimal allocation and necessity of implementation,mainly researched such basic theories as basic principle ,dispose the way ,the goal of optimal allocation of contents of optimal allocation of water resource that the system has been described and so on .Have discussed the realization mechanism of optimal allocation of water resource in detail.The balance relation that should noticed during the course of water resource allocation has been described.Several kinds of main water resource allocation theories and developing direction at the same time were discussed .4.Have described the target of studying in rational distribution system in detail,namely has done exhaustive description to every respect of the system.build the water resource distribution model that the water quality and water quantity jointly disposes. And analysed the project of the rational distribution of resources of water by project measures,and analysed by project measures the project of the optimal allocation of resources of water at the same time.5. Finally, the water resources optimal allocation results are summarized and the perspective studies in the future are put forward.
