MULTI-OBJECTIVE PROGRAMME MOLD OF TROPICALCROPS IN HAINAN ISLAND
海南岛热带作物多目标规划模型

: According to biological characters, realistic productive structure of tropical crops and climatic condition of a district in Hainan Island, this paper carried on regional division of tropical crops in the fuzzy mathematics; based on calculation of basic parameters of forming production in regions. It established near-term models of structural optimum of tropical crops of every region by using method of multi-objective program; and set up grey far-term program model 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.
