摘要
本文应用多目标线性规划方法,在系统分析的基础上,对江苏省丹阳市珥陵镇以“综合型”、“粮—桑协调型”及“蚕桑型”为发展方向的三种类型农业生产结构进行模拟优化,取得不同情况下的优化方案,为珥陵镇农业生产提供决策依据,以实现经济、生态和社会效益的整体最优。三个模型优化方案在保证一定的社会与生态效益的前提下,可以使珥陵镇农业生产总收益分别提高19.6％、28.8％和45％。
In this paper, multiple objective linear programming has been applied to optimize the agricultural production structure for Erling township of Danyang county. Three kinds of agricultural production system were studied according to their developing directions. They were: 'the Integrated Pattern', 'The Grain-Sericulture Pattern' and 'the Sericulture Pattern'. Based on the system analysis, three mutiple objective linear programming modelhave been estab lished. The optimizing operations showed; according to thcconcrete conditions of Erling township,the three kinds of model could be adopted for different situations, the optimizing operations provided scientific basis for the decision of agricultural strategies for Erling township to obtain the best economic, ecological and social benefits. The optimized results of three kinds of models could increase the economical income of Erling townchip by 19. 6%, 28. 8%and45%respectively.
