【摘要】 将灌区的经济效益和生态环境效益结合在一起综合考虑,在灌区水资源配置时不仅只追求获得最大经济效益,同时尽量将地下水位控制在适宜范围内,以维持地下水资源的采补平衡,实现水资源的可持续利用。按此原则,建立了井渠结合灌区水资源多目标优化配置模型。实例计算表明:应用此模型指导井渠结合灌区的水资源配置可实现真正意义上的地表水和地下水联合运用,提高水资源利用效率。更多还原

【Abstract】 When the water resources is allocated,the economic benefits and ecosystem environmental benefits of irrigated area should be considered at the same time,the purpose of water resources allocation is not only to obtain the greatest economic benefits,but also to control the groundwater level between the suitable range to maintain the groundwater resources equilibrium of exploitation and complement and to realize sustainable use of water resources.Based on the rule,a multi-objective optimal allocation model of water resources in well-canal combined irrigated area was established in this paper.The application result showed that the model can realize conjunctive use of surface water and underground water in deed and improve water resources use efficiency.更多还原
