摘　　要：近十年来,随着昆虫生态学研究尺度的增加,大量数据的处理成为一个重要的问题。本文介绍了4种简单的原始数据处理及变换方法,使得不同量纲的变量能够在同一个平台上进行统计分析,并简要论述了数据变换后进行分析的特点和优势。In the past decade,as rapid increasing of scale in insect ecology,how to analyze a large number data at the same time have become an important problems.In this paper,4 methods of data preprocessing were illuminated,which were min-max normalization,zero-mean normalization,log transformation,and inverse trigonometric function transformation.These methods made many variables of different dimensions to analyze at the same time.Finally,the advantage and characteristics of these methods were summarized.
