On Optimal Allocation Model of Water Resourcesfor Agricultural Irrigation

提出了在因素不确定条件下的多目标水资源优化配置模型。该模型综合了机会约束规划、半无限规划和整数规划,是一个区间线性规划。通过把灌区的经济效益、社会效益和生态效益视为最佳的目标函数,最终得到了灌溉水资源(地表水和地下水)在不同的水文年的配置概率。在综合考虑节水措施、灌溉水质影响因素和地下水资源可开采量的多重动态影响因素的基础上,建立了不确定环境下的多目标灌溉水资源优化配置模型。

This paper proposes a multi-objective optimal allocation model for water resources under uncertain conditions of indeterminancies. The model integrated a chance-constrained programming,semi-infinite programming and integer programming,and it is an interval linear programming. By seeing the economic,social and ecological benefits of irrigation area as the best objective function,this model gets a configuration probability of irrigation water resources（ surface water and ground water） in different hydrological years. Considering water saving measures,irrigation water quality and groundwater resources exploitation on the basis of multiple dynamic factors,this paper established multi-objective optimal allocation model of water resources for irrigation in uncertain environment.
