摘　　要：为明确昆嵛山腮扁叶蜂(Cephalcia kunyushanica)的出现与林下植物是否关联,本研究在昆嵛山林区设置的50块永久样地内,应用样圆法进行了灌草层植物调查,并基于2×2联表,应用总体方差分析、χ2统计检验、Ochiai关联度指数、Dice指数、联结系数、共同出现百分率、点相关系数以及Cramer指数等指标,分别对昆嵛山腮扁叶蜂与邻近环境中所有195种林下植物种群的总体相关性、该昆虫与各植物构成的物种对之间联结显著性以及联结强度进行了测度。结果表明:(1)昆嵛山腮扁叶蜂与195个植物物种种群总体存在极显著的正相关;(2)该食叶昆虫与83个物种分别构成的物种对呈正联结关系,与另外112个物种分别构成的物种对呈负联结关系,负联结的比例高于正联结;(3)该昆虫与羊胡子草(Carex rigescens)等11种植物具有极显著的正联结关系,与宽叶苔草(C.siderosticta)等16种植物具有极显著的负联结关系。Based on the sample-circle method and the 2 × 2 contingency table of species presence /absence data collected from 50 permanent plots in Kunyushan region,the VR analysis,χ2-test,association coefficient,Ochiai association index,Dice association index,point correlation coefficient,Cramer index,and percentage co-occurrence were used in quantitative analysis of the inter-specific correlation of Kunyushan web-spinning sawfly（ Cephalcia kunyushanica,a defoliator） occurrence and adjacent understory plants of natural forests in Kunyushan region. The results indicated that there was a significant positive correlation of overall association existing among Cephalcia kunyushanica and 195 neighboring shrub or herbage plants（ P〈 0. 01）. The result of χ2-test showed a positive association for 83 species-pairs and a negative association for112 species-pairs. The ratio of negative pairs was higher than positive ones. Furthermore,the insect showed extremely significant positive inter-specific correlation relations to 11 species including Carex rigescens,while negative ones to 16 species including Carex siderosticta respectively（P〈 0.01）.
