摘要: 本文从海南热带作物生物学特性、现实生产结构和地区气候条件出发、对热作种植业进行了模糊区域性划分;在计算构成各区产量基本参数的基础上,应用多目标规划方法,建立了热作结构优化的近期分区模型;并通过近期基础模型和对未来参数的预测,建立了远期灰色规划模型。结果表明,近期方案可提高收益5.1-55.7%,远期方案可提高54-90%,远近期方案均取得了明显的经济效果。

Abstract: According to biological characters, realistic productive structure of tropical crops andclimatic condition of a district in Hainan Island, this paper carried on regional division oftropical crops in the fuzzy mathematics; based on calculation of basic parameters of formingproduction in regions. It established near-term models of structural optimum of tropical cropsof every region by using method of multi-objective program; and set up grey far-term programmodel through nearterm basic model and prediction of the future parameters. Results indi-cated that near-term program may raise profit of 5.1-55.7% and farterm program of 54-90%, far and near program scheme takes obvious economic effect.
