摘要
本文应用线性规划原理,建立了湖南中部丘陵地区邵东县水田种植制度优化模型。优化过程中,以净产值(不包括利息和税金)为目标函数,对总面积、主要作物播种面积、适宜用地、冬闲田等进行了约束。优化结果净产值可增加17801900元,增长了14.4%。
With net output value of the crops asthe objective function and total farming area, planting areas of main crops and optimum conditionsfor growing crops as the controlled, an optimummodel is programed, bringing to Shaodong county17.8 million Yuan of extra net income, or 14.4%increase of net output value over that with non-op-timum programming.
