果树种植最佳土地租赁期的数学模型建构

The Mathematical Model of the Optimal Land Leasehold of The Fruit Tree Planting

以种植果树为例,根据果树种植的客观规律,引进折扣因子δ=U-α,给出了通过确定投资合同期使利润达到最大的数学模型,并进行了讨论和推广.

This paper take the fruit tree planting for example, introduce into the δ=U-α. According to the law of the fruit tree planting, the mathematical model was eatabiished, it was about the optimal profit based on deiding cost and contract period. Finally, the model is discussed and popularized.
