Allocation Of Water Resource And Ecological Economic Coordinated Development In HeXi Region

The shortage of water and its impact on sustainable development has drawn wide and great attention around the world. HeXi Region in GanSu Province as aridity and semiarid rejoin, the shortage of water and environment problems are very serious.At present the annual average shortage of water in River-Basin reaches 6-8(108m3). Considering the growth of population, urbanization and industrialization, the lack of water will continue in the coming 15 years, which will greatly influence the regional development. Meanwhile the ecological problems caused by lack of water are becoming very serious, such as the intermittent of river, the descent of underground water, the degeneration of vegetation, the expansion of desert, the oasis around downstream of Black River and Stone Sleep River which have been the main seminary of dust storm in North China. The shortage of water and ecological problems related with it has been the essential problems that restrict the sustainable development of HeXi Region.Besides the limitation of water supply, the essential reason for these problems is the imperfect of water allocation system which can't encourage the valid allocation of water resource and protect environment, such as water resource property right isn't very clear, the price system has shortcoming, the management system isn't imperfect, etc. Consequently innovating existing system and building perfect water allocation system is the key to achieve both economic and ecological value of water.The special nature of water resource and its multiple function determine that the allocation system is complex. The paper regards that the system innovation for HeXi Region should involve following points: establishing water right system that can be traded in the market and using the market mechanism to improve validity allocation of water; adjusting existing price system and make it not only reflect scarcity and cost of water, but also include its ecological value; carrying out regional unification governing to make water resource fairly allocated by regions, to insure the ecological need of water and protect environment, to economize using of water. By the system innovation the multiple value of water in HeXi Region would be achieved.
