| Abstract: |
| 【Objective】This research is to explore rational allocation scheme of water resources in Taiyuan City to use limited water resources rationally and to promote sustainable development of economy and society.【Method】 The multi-objective optimal allocation model of water resources is established by taking the economic development and water environment protection in corresponding area as the objective in this paper.Based on this,aiming at different standard years (2010,2020 and 2030),the optimal allocation of the water resources in Taiyuan City are analyzed by using large-scale system decomposition-coordination method.【Result】 The supply and demand contradiction will intensify increasingly under condition of existing water supply engineering and general water-saving scheme.The water shortage ratio in the whole city will rise from inadequacy 1% and 7.7% (2010) to more than 35% (2030) in 50% or 75% hydrological year;As adopting high water-saving scheme,the water shortage ratio in the whole city will be 26% to 31% in 50% or 75% hydrological year.【Conclusion】 To solve the problem of water shortage fundementally,the measures including broadening sources of income and reducing expenditure and dealing with sewage must be taken simultaneously. Based on increasing water-saving force further,the sewage treatment of various industrial economic departments and diversion from Yellow River must be stressed. |
