摘要
为了探索玉米螟种群动态的预测预报,作者应用了物元概念和关联函数,确定”了玉米螟种群动态分级的经典域物元和节域物元,建立了分级预报的物元模型.检验结果表明,模型的历史拟合率达100%,1995、1996两年预报,其结果与实际一致.为害虫种群动态的分级预报提供了一种新的研究方法.表2，参7。
In order to investigate the prediction of the Corn Borer, using the concepts of matter -elements and dependent function, the classified prediction model of matter - elements of population dynamics of the Corn Borer is proposed on the basis of designing classical and extensional matter-elements. The tested pest data showed that the fitting rate come up to 100% , and accuracy of forecasting for 1995 and 1996 is satisactory. This new method may be tried for forecasting of other the population dynamics of pests.
