摘要
建立了以扶余灌区经济效益、节水效益和生态效益为目标的作物种植结构优化模型,提出了灌区种植结构的不同调整方案。模型建立后,采用模糊折中规划方法将多目标函数转化成单目标函数,运用MATLAB软件进行求解。结果表明,该灌区在优先考虑灌溉成本兼顾其他目标时,旱田与水田的种植面积比例为1.53∶1,旱田全部种植玉米;优先考虑节水效益兼顾其他目标时,灌区全部种植玉米;优先考虑生态效益兼顾其他目标时,旱田与水田的种植面积比例为1.48∶1,玉米与大豆的种植面积比例为0.99∶1。
Economic efficiency,water saving benefit,social benefit and ecological benefit as the goal of the crop planting structure optimization model of Fuyu irrigation area was established.This paper put forward the different planting structure adjustment plan.After the model was established,using the fuzzy compromise programming approach to multiple objective function was transformed into a single objective function.The model was solved via MATLAB software.The outcomes show that when priority is given to the irrigation cost into account other goals,upland and paddy planting area ratio is 1.53∶1 and corn is planted in all upland field.When priority is given to water-saving benefit into account other goals,corn is planted in all irrigation area.When priority is given to ecological benefit into account other goals,upland and paddy planting area ratio is 1.48∶1 and corn and soybean planting area ratio is 0.99∶1.
