摘要
本文研究了山东省２１个地、市（县）贮粮昆虫群落结构的数量特征，分析了它们的相似性。利用系统聚类将２１个群落分为６类，分析了各类的特点，为科学管理贮粮害虫提供了依据。同时，以泰安粮食局为系统调查点，分析了时间序列上的群落数量特征。
Numerical characteristics of stored grain insect community structure from 21 different areas,such as species richness,diversity,ecological dominance and evenness,were studied.The similarity of 21 communities was also analysized by sΦrensen's index.Twenty-one communities were divided into 6 groups by hierarchical cluster analysis.Meanwhile,numerical characteristics of Taian Grain Bureau insect community in different temporal sequences were studied systematically
