摘　　要：本文从多元统计分析入手，对河南省中牟县历年大豆虫害情况，采用贝叶斯逐步判别分析方法。Based on the multivariate analysis for the number of soybean insects in Zhongmu of Henan,the prediction model for annual total amount of soybean hawkmoth(clannis bilineata walker)and that for the daily maximum amount were established by the method of Bayesian stepwise discriminant analysis.
