摘要
随着沿海开发国家发展战略的实施,南通市规划并建成了一批开发区,对水资源保护与利用产生了较大影响。为了优化配置南通市水资源,综合考虑社会、经济和环境三方面因素,构建了水资源优化配置模型,并用SCE-UA全局优化算法进行模型寻优计算,得到了南通市水资源优化配置方案。模型计算结果显示:到2015,2020年工业、第三产业等最佳用水可以得到满足;由于农田灌溉水利用系数偏低,农业用水无法满足最优配置要求,未来应着力提高农业用水效率,减少耗水。
In recent years, the coastal development has become a national strategy and Nantong City has planned and built a batch of development zones, which exerts a great impact on water resources protection and utilization. For optimal allocation of water resources in Nantong City, by comprehensively considering on 3 factors of society, economy and environment, a water re- sources optimal allocation model is established and the Shuffled Complex Evolution （SCE -UA） method is used in the model to search the optimum value. The results show that the water resources of Nantong City can meet the optimal allocation requirement for the second and the third industries by 2015 and 2020; due to low irrigation water use coefficient, the optimal agriculture water use can not be met. In future, the city should improve the irrigation water use efficiency and reduce the water consumption.
