摘要
针对农业水资源优化配置中降雨量的不确定性问题,在传统区间规划的基础上,引入双区间规划理论进行描述,以农民种植净效益最大为目标函数,建立地表水和地下水联合灌溉的作物灌溉水量优化模型。实例应用于武威市民勤县红崖山灌区,对灌区农业水资源优化配置进行研究,模型计算结果表明:利用双区间规划对作物进行灌溉水量的优化,春小麦、春玉米、籽瓜的灌溉定额分别为:[[179.81,191.81],[353.89,365.89]]、[[119.46,141.46],[270.57,292.57]]、[[180.04,213.04],[267.49,290.49]],相比于现状,节水量分别为3%、27%、4%。利用双区间规划不仅能够更好的解决灌区多作物灌溉水量优化问题,而且能够给决策者提供更大的决策空间。
Aiming at the uncertainty of rainfall in optimal allocation of agricultural water resources,based on the traditional interval planning,the theory of dual-interval planning was introduced,and the maximum net benefit of farmers＇ planting as the objective function was used,and the combination of surface water and groundwater irrigation optimization model of crop irrigation water was established in this study.Hong Yashan Irrigation District of Minqin County,Wuwei City was taken as study object,The results show that the dual-interval programming to optimize irrigation of crops,wheat,maize,seed melon.The irrigation quotas were：[[179.81,191.81],[353.89,365.89]],[[119.46,141.46],[270.57,292.57]],[[180.04,213.04],[267.49,290.49]].Compared to the current situation,the amount of water saving reached 3%,27%,4%.It was found that the use of dual interval planning not only solved the problem of irrigation water optimization in irrigation area,but also provided greater decision space for decision makers and increased the practicability and reliability of the model.
