Water Resources Optimal Allocation Research For Luannan County

Water is the source of live and the basis of substance. Water resources are the foundational natural resources and the strategic economical resources. To achieve the sustainable development of the society and economy, we must realize the sustainable use of water resources first. Luannan County is a county of Hebei Province which majors in agriculture. With the social and economic rapid development, the quantity of water requirement is becoming much higher, but the available water resources is limited, so the contradiction between water supply and requirement is very heavy, and the groundwater exploitation coefficient of the water resources subarea in which there is the county seat of Luannan County has been 1.27, which belongs to commonly exceeded exploitation. Water resources optimizing allocation, namely maximizing the efficiency and benefits of water resources will be the certain choice for sustainable development of Luannan economic society. In this thesis, how to effectively use the limited water resource has been discussed.By analyzing Luannan County's surface water and ground water and so on, Luannan County's available water quantity is received. By water supply survey and society and economy water using survey and water using analysis in present year and water resources exploitation and using analysis and water resources supply and require analysis in present year and so on, water resources exploitation and using existent problem and contradiction between supply and requirement are opened out, which affords basic data for the optimization distribution of limited water resources in Luannan County.By forecasting Luannan County's population quantity and the ratio between town and village and the increased value of three industries and water requirement ration in the condition of aggrandizement economy water using, water requirement quantity in plan level years is received. In according of water requirement quantity in plan level years and consulting interrelated water supply programming, available water supply quantity is received.In allusion to the characteristics that Luannan County is a county which majors in agriculture and its area is small and its water resources allocation is relatively easy and the contradiction of water resources allocation among industries is severe and so on, based on the predicted water supply and demand for Luannan County, water resources multi-objective optimal allocation model is founded. The model are made up of primary object which is that the district economical benefit is most and by-end which is that the district social benefit is most and restricts which contain water supply capability and water transportation capability and water demand capability and so on. And the model is solved through data input with Excel and transferring Tool Function linprog of Matlab, and then the allocation production is received. By analyzing, the allocation production is believed reasonable and feasible, and it can be decision-making gist of Luannan County water resources layout and management.Economy water using scheme and increasing water supply scheme and water resources integration management construction scheme are established to ensure water resources optimization allocation fruit realized at right, and the effect is appraised after schemes carried into execution. After schemes carried into execution, water resources supply indemnificatory ability is basically harmony with economic society development and entironment protection, and the whole water resources restriction has lessened.
