Numerical characteristics of insect community structure in five stored export products along Yangtze River in Jiangsu Province
对江苏沿江地区出口产品仓储昆虫进行调查，分析了5种出口产品仓储昆虫群落的优势种.利用群落物种的丰富度、生态优势度、多样性和均匀度等群落特征指数，研究了5种类型出口产品仓储昆虫群落结构的数量特征，并分析了它们的相似性.通过系统聚类分析将5种群落分为4类，草柳藤制品和羽绒制品仓储昆虫群落同属一类，其它3种产品仓储昆虫群落各属一类.除木制品群落结构相对合理外，其它群落结构都不合理，皮毛制品群落结构尤其不合理.
This paper investigated the dominant species of insect communities in five stored export products along Yangtze River in Jiangsu Province.With the indexes species richness,ecological dominance,community diversity and evenness,the numerical characteristics of insect community structure in the stored products were analyzed,and the similarity of the communities was also analyzed.By the method of hierarchical cluster analysis,the numerical classification was made,and the communities were grouped into 4 groups.The insect communities in stored willow and feather products were in the same group,while those in other stored products were grouped into 3 groups.Except that in woodwork products,the insect community structures in other stored products,especially in leather products,were not rational.
