摘要
本文用系统聚类法和Ｆｉｓｈｅｒ准则判别分析法，研究了杉木种子等级的划分，将杉木种子划分为Ⅰ、Ⅱ、Ⅲ三个等级，判别结果准确率达９５．２４％。本文旨在为进一步研究和合理地划分杉木种子等级提供科学依据。
In this article,applying systematic clustering methods and discrimination analytical
methods fromFisher norm,the division of seed grades of Cunninghamia lanceolata was
studied.The seeds of C.lanceolatawere divided into 3 grades and the accurate rate of the
discrimination was 95.24%.This article aimed at pro-viding a scientific basis for the further study
and reasonable division of the seed grades of C.lanceolata.
