Abstract:
Water resources shortage is an important factor restricting the economic and social development of the city. Rational allocation and effective use of limited water resources is an effective way to solve the contradiction between water supply and demand. Xuchang City is taking as an example for national water ecological civilization city construction in this paper. The water demand is forecasted by the quota method according to the analysis of the status of water resources development and utilization. Based on the multi-year average water resources, 2011 is taking as the research base year. According to the water resources access, engineering scheme and various water demands, etc. MIKE BASIN is used to establish the water resources allocation model. The water supply and demand balance is simulated in Xuchang City. The water supply and demand allocation is obtained in different planning levels through three times of supply and demand balance analysis program, and ultimately to achieve water supply and demand balance, so that the limited water resources can maximize efficiency. The research results show that the local water resources can be combined with the multi-mode joint operation of South-to-North water diversion, Yellow River water diversion and reclaimed water reclamation to meet the water demand of Xuchang City in the medium-long term sustainable economic and social development. It also has significance guide for the future sustainable utilization of water resources in Xuchang City.
