基于双区间规划的武威市民勤县3种作物灌溉水量优化模型研究
Research on dual-interval programming for optimal irrigation model of three crops in Minqin County,Wuwei City
摘要
Abstract
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.关键词
