Study On Optimized Allocation Of Water Resources In Kaidu River-Kongque River Basin

Water as a resource is to support the social, economic and ecological environment for sustainable development is an indispensable element. Water is generally considered to be fundamental resources to he survival and development of human and can not be replaced, Water is an important foundation for the sustained and healthy development, while maintaining the natural ecosystem functions and biodiversity, protection of regional economic and social for sustainable development of resources.With the rapid development of the socio-economic constraints of the shortage of water resources for economic development have become increasingly prominent, as a key factor restricting the development of various industries. Long-term view and strategic point of view, the rational allocation of limited water resources, improve the utilization of water to alleviate water supply and demand. Water resources rational are one of efficient ways to solving water shortage. Through the rational allocation of water resources to ensure the sustainable use of water resources, in order to achieve sustainable socio-economic development is a serious problem.In this paper, Kaidu River-Kongque River Drainage Basin was selected as a case study site, The fixed method was applied in the study that was based on the social and economic data of the Kaidu River-Kongque River Drainage Basin during the years from1989-2009;application of principal component regression analysis, the gray model and BP neural network model of basin water demand simulation and prediction; build a basin of water resources optimal allocation model to calculate the parameters of the water supply coefficient and the water sector the coefficient of equity, effectiveness factor and cost factor, calculate the fair coefficient of water supply coefficient and the water sector, the effectiveness factor, and cost factors and other parameters; to Drainage Basin, water supply and the water consumption of different departments for the constraint conditions, the software Matlab optimization toolbox of the model was solved, and finally get the initial optimal allocation scheme. The results of important reference value for the development of the River basin’s water resources, sustainable use and socio-economic health development planning of important reference value.The main results of this paper are as follows:(1)The fixed method was applied in the study that was based on the social and economic data of the Kaidu River-Kongque River Drainage Basin during the years from1989-2009.It shows that an obvious increasing trend for water demand of the four sectors:the urban greening, secondary, industry, tertiary industry and agriculture was shown. The water demand for agriculture was more consistent was the total water demand; Agricultural irrigation water demand accounted for above90%of the total and it is the major demand approach within the river drainage basin. It was found that the change in total water demand was dominated by the increase or decease of the River Basin.(2)Application of principal component regression analysis, the gray model and BP neural network model of basin water demand simulationThe results show that with the principal ingredient analysis method was suitable to forecast the total water demand in the River Basin, the gray model was suitable to forecast the other social and economic data in the River Basin.(3)According to Drainage Basin analysis of current situation of water resources use, build Kaidu River-Kongque River Drainage Basin water resources optimal allocation model to determine the model parameters, Solving programming software Matlab Optimization Toolbox, the basin water resources to optimize the configuration program, and allocation of water resources resultsanalysis provides a basis for River Basin Water Resources planning and Management.
