摘    要:本文的数理统计采用了Fisher准则下的两类判别分析方法,在PC-1500型袖珍电脑上,对无锡地区的历史资料进行了数量分析,建立了预测无锡地区三化螟第一代发生量的线性判别函数。对于历史资料的回代验证,拟合率在90%以上,试报准确率是高的。

关 键 词:三化螟  预测预报  生物数字  判别分析

Abstract:From the discriminatory analysis of Fisher's criterion, the authors deduced linear discriminant functions forecasting the oecurence amount and period of the first generation for paddy borer, Tryporyza incertulas(Walker). Choosing the weather factors relating to the pest insect for independent variables. The results to test the pest data showed that the fitting rate was over 90%, and that the accuracy of forecast was right.
Keywords:Paddy borer  Forecast  Biomathematics  Discriminatory analysis
