摘　　要：针对利津县当地灌溉水资源远远不能满足农田灌溉用水的难题,采用亏缺灌溉的调控方式控制作物生育期灌溉用水量,选取作物经济效益、综合水分生产力、生态效益最大为目标,运用多目标优化模型(AE-FOS-MOP)进一步对利津县不同水平年下的农作物进行种植结构调整。研究表明:①亏缺灌溉方式下,灌溉水量仍不能满足农田灌溉用水需求,但显著缓解了灌溉水供需矛盾。②在保证粮食安全生产的前提下,不同水平年下模型优化的结果有效地调整了粮经作物的比例并实现了节约耕地。③现状年(2022年)通过调减冬小麦、水稻、玉米、棉花的播种面积,增加花生的播种面积,可实现经济效益提升1.9%,综合水分生产力提升4.5%,生态效益提升3.1%。④规划年(2025、2035年)进一步增加蔬菜、花生的种植规模,经济效益分别提升9.5%、14.3%,生态效益分别提升16.9%、14.1%,综合水分生产力分别提升2.1%、5.0%,节水率分别为8.2%、5.5%。Considering the problem that local irrigation water resources in Lijin County are insufficient to meet farmland irrigation needs,the deficit irrigation method is adopted to control irrigation water consumption during the crop growth period,maximizing economic benefits,comprehensive water productivity,and ecological benefits are selected as objectives.The multi-objective optimization model(AE-FOSMOP)was used to adjust the crop planting structure in Lijin County under different annual conditions.The results show that:①under the deficit irrigation mode,the irrigation water amount still cannot fully meet farmland irrigation demand,but it significantly alleviates the supplydemand contradiction.②Under the premise of ensuring food security production,the results of model optimization in different levels of years effectively adjust the proportion of grain and grain crops and realize the saving of arable land.③By reducing the sowing area of winter wheat,rice,corn and cotton and increasing the sowing area of peanut in the current year,the economic benefit can be increased by 1.9%,the comprehensive water productivity by 4.5%,and the ecological benefit by 3.1%.④In the planning year,the planting scale of vegetables and peanuts will be further increased,the economic benefits will be increased by 9.5%and 14.3%,the ecological benefits will be increased by 16.9%and 14.1%,the comprehensive water production will be increased by 2.1%and 5%,and the water saving rate will be 8.2%and 5.5%.
