摘要
本文以与茶梢蛾种群发展相关的11个因子为指标,在主成分分析基础上,运用建立在模糊集合理论基础上的ISODATA聚类分析方法,对丘陵区茶梢蛾的为害类型进行了数量划分.划分结果客观、具体,与实际情况相符。
Quantitative classification of the injurious pattern of the tea shoot borer, Parametriotes thene, in the hilly land was conducted by applying principal component analysis and ISODATA method based on fuzzy theory. 11 factors in relation to population development were considered.
