摘要
以随机过程为数学工具,用金融风险管理的思想,研究随机波动的害虫种群对作物造成的损失和药物防治费用之间的关系,依据最优经济效益原则确定害虫的最优防治阈值与防治时刻.
The relation between crop's cost and insecticide cost for preventing the random walking insect's population was found by means of the theory of stochastic processes and the idea of managed financial risk, the formula to determining the optimal threshold and moment for preventing insects was gained based on the economical optimal principle.
