摘　　要：为了优化配置红寺堡灌区的作物种植结构,在分析灌区现状作物种植结构的基础上,采用单目标模型的形式,结合多目标模型的思想,建立了基于水资源利用的作物种植结构优化模型,并计算了灌区2008年和2015年在灌溉保证率为75%的最优作物种植结构。结果表明:在总种植面积不变的情况下,优化后小麦、玉米、薯豆类、葡萄、油葵等作物的种植面积有所减少,拱棚蔬菜、甘草等作物的种植面积有所增加。2008年和2015年红寺堡灌区优化后较现状种植结构不仅可以分别节约水量1 617.4万m3和1 821.7万m3,而且可以分别增加农业收益9 577万元和11 281.1万元。In order to optimize the planting structure in Hongsibao irrigation district, this study firstly analyzed the current planting structure, then found and solved optimization model for planting structure in the form of single-objective model and with the idea of muhi-objective model based on the use of water resources in 2008 and 2015 in the case of 75 % hydrological year. The results show that the optimized area of wheat, corn, potato, grupe and sunflower have been reduced and the optimized area of vegetable and licorice increased comparing with the current planting area. The planting structure optimization in 2008 and 2015 in Hongsibao irrigation district can not only reduce agricultural water use 1 617.4 × 104 m^3 and 1 821.7× 104 m^3 than that of current planting structure, but also can increase agricultural benefits 95.77 million RMB and 112.81 million RMB respectively.
