Studies on the Economical Benefit, Ecological Efficiency and the Modeling of the Double-cropping Rice Farm Ecosystem Ⅲ.The Economic Decision-making Model of Adjusting the Planting Type in Double-cropping Rice Farm
【摘要】 运用C -D函数 ,选择农产品价格、农业生产资料价格及单位面积 (hm2 ,下同 )产量为决策变量 ,以单位面积收益为目标函数 ,建立了双季稻农田种植调整和经济决策模型
【Abstract】 This paper deals with an economic decision-making model of adjusting the planting type in double-cropping rice field using cobb-Douglas function, which takes benefit/hm 2 as goal function, and the price of the agricultural production, the price of the agricultural producer goods and yield/hm 2 as decision-making variates.
