Study On Water Resources Optimal Allocation In Hailin

Accompanying the increase of the population and the fast development of the economy, the allocation between the supply and the demand of the water resources stands out increasingly. At the same time, environment becomes worse and worse due to the excessive development and utilization of water resources which is a severe challenge to the sustainable development of social economy in the 21st century. And Consequently broad concern has been aroused by the rational allocation and the sustainable utilization of the water resources in the academia and the whole society. In the article, the Hailin town is the studied area in Mudanjiang city, Heilongjiang province. The author studied the overall arrangement of social economic development and the requirement of the water resources in the future, through analyzing present situation and the current problems of the development and utilization of the water resources in the studied area.In allusion to the shortage because lacking of water supplying projects in the studied area, according as three-balances idea of the water resources allocation, the balance analysis have been done respectively both based on current situation development and utilization mode of the water resources, and on current scale of water transfer projects and the consideration of water saving, pollution control and potential excavation of the water supplying. And then generate schemes under different development mode in different horizontal years on expert rule. Coordinating the relation between water supply and demand so that the balance between them can be realized ultimately. Which can sustain the harmonious and healthy development among social economy, water resources and environment.In order to appraise the effect of the water resources optimal allocation schemes, the author established the appraisal model on AHP. According to index system established which have twenty indexes in six classes, we can realize appraising and optimum selecting scheme through combining AHP with the method of expert consults. Compared with the rational appraisal in traditional planning work, the author drew the same conclusion. It is proved that this method is helpful to select one which is correspond to reality from different schemes. Which make the research results can guide or be applied in management of regional water resources.From the example studying and the calculation, we can conclude that in the studied area there is a shortage because lacking of water supplying projects, we can resolve the shortage problem of water resources, through excavating potentiality, and enlarging the development scale of water resources, In course of which the adjustment of the industry structure, water saving and pollution control will be very important for the balance between water supply and demand. It is unnecessaryto building water transfer projects.
