摘　　要：通过对30块样地资料的聚类分析,将平陆县锈色粒肩天牛为害分布类型划分为5类:第 类,低虫口密度、低被害株率、较高拥挤度;第 类,较高虫口密度、较高被害株率、高拥挤度;第 类,虫口密度、中等被害株率、较低拥挤度;第 类,较低虫口密度、较低被害株率、低拥挤度;第 类,高虫口密度、高被害株率、中拥挤度。Through cluster analyses of data from 30 sample lands,damage distribution types caused by Apriona swainsoni in Pinglu county were divided into 5 categories:Ⅰ.Low insect density,low attacked trees rate,higher crowded degree;Ⅱ.Middle insect density,higher attacked trees rate,high crowded degree;Ⅲ.Higher insect density,middle attacked trees rate,lower crowded degree;Ⅳ.Lower insect density,lower attacked trees rate,low crowded degree;Ⅴ.High insect density,high attacked trees rate,middle crowded degree.
