武威市种植业粮-经-饲三元结构优化模式研究

Studies on the Optimization Model of Ternary Structure of Grain,Economic Crops and Feed in the Planting Industry in Wuwei City

采用线性规划的原理与方法,对武威市种植业结构进行分析,结果表明:①武威市目前种植业结构不合理的主要原因是粮食作物比例过大(72.9%),饲料作物面积太少(1.1%);②武威市农业持续、高效发展的有效途径是建立种植业粮-经-饲三元结构,大力发展养殖业,增加农民收入;③武威市今后的粮食生产应以高产节水型的间套作为主,积极发展高产、高效的经济作物;④武威市种植业粮经饲合理比例应为42.3∶22.1∶35.6,预计2030年的合理粮经饲比例为31.1∶26.5∶42.4。

Using the principles and methods of the linear programming,the structure of the planting industry in Wuwei City was analyzed.The results showed that the main reasons that caused the unreasonable structure of the planting industry in Wuwei City included too high proportion of grain crops（72.9%）,less area of feed crops（1.1%）.The effective ways of sustainable and efficient agricultural development in Wuwei City were to set up the ternary structure of grain,economic crops and feed in the planting industry,develop the breeding industry vigorously,increase the farmer＇s income.In the future grain production in Wuwei City,high-yield and saving-water intercropping should be taken as main,highyield and efficient economic crops should be developed actively.The reasonable proportion of grain,economic crops and feed in the planting industry in Wuwei City was 42.3∶22.1∶35.6 and the reasonable proportion of grain,economic crops and feed in 2030 would be 31.1∶26.5∶42.4.
