| 摘 要： | 从植物病害流行结构分析入手,导出了以Logistic模式描述病害流行系统管理战略决策的数学模型:Z=In((1-X0)/X0)-r*t,并给出了相应的使用准则。初步试用的结果表明:它不仅十分简便和经济,而且是值得信赖的。

| Abstract: | By the analysis of plant disease epidemic structure, a model for the strategical decision in plant disease management, which is Z=ln(1-X0)/X0] -r*t, was deserived from the Logistic system. Preliminary practical results showed that it is very simple and very covenient to use, as well as reliable and economic. |
