Kunming City Water Resources Optimal Allocation

Water is an origin of life, water resources is a fundamental and strategic natural resources. With the rapid development of social economy, expansion the size of the city, and the rapid population growth in Kunming, the water in Dianchi lake is heavily polluted,and there is an contradiction between supply and demand of water resources of Kunming. The shortage of water resources and water pollution have become the main important factor restricts the city development and economic growth of Kunming.This paper has first summarized the significance of the optimal allocation of water resources, introduced the general situation of water resources in our country and the world, discussed the present situation and the research dynamic of optimal allocation of water resources at home and abroad,and briefly introduced the research contents and technical route.As a study area,discussed the geographical position, the administrative division, the topography and the climate characteristics of natural geography condition and social economy of Kunming. Analyzed the present situation of development and utilization status of water resources of Kunming, researched the causes of the pollution and summarized the problems of water resources of Kunming, and aimed at the shortage of water resources of Kunming gave some methods to solve them.Predicted the domestic water, industry water, agriculture water, ecological environment water and urban public water in different planning level years under different assurance.Forecasted the water supply under the level of planning years, and analyzed the current situation and planning level years supply and demand balance under different assurance and the results.On the basic of analysis multi-objective programming of principle, characteristics and theoretical basis and introduced some solutions, established the optimal allocation of multi-objective model combined the situation of water resources of Kunming.Solved model.through the model got configuration optimization schemes of planning level years under different water assurance and analyzed the schemes and summarized some security measures of them.Summarized the content of the paper.and gave some suggestions for Kunming to realize the sustainable utilization and optimized allocation of water resources.
