2007年6～9月对黑里河自然保护区昆虫进行了系统调查研究,并用多样性指数对昆虫的多样性进行了测度.采集到该区昆虫223种,分别隶属干11目65科176属.群落的α多样性分析结果表明:不同群落多样性指数的变化顺序是蒙古栎林林缘群落＞白桦林林缘群落＞河滩草地群落＞平榛林林缘群落＞人工针叶林群落；在5个不同群落中,蒙古栎林林缘群落昆虫的物种数、个体数、物种多样性指数及物种均匀度指数均高于其他群落.群落的相似性分析和聚类分析结果表明,不同群落昆虫之间的相似性差异显著,昆虫群落多样性变化主要与植被类型有关.%The insects collected from Heilihe National Natural Reserve in Chifeng of inner Mongolia were investigated systematically from June to October in 2007, and various diversity indexes were used to test insect diversity in the reserve. The results indicated that there are 223 species of pollinators, which belong to 11 orders, 65 families, 176 genera, a-grade community diversity analysis indicated that the order of five communities diversity indexes was: Quercus mongolica forest edge community > Betula platyphylla forest edge community > riverside meadow community > Corylus heterophylla forest edge community > man-made coniferous forest edge community. In five different communities, indexes of insects in the Quercus mongolica forest edge community, such as number of species, individuals, species diversity index and species uniformity indexes were higher than those of other four kinds of communities. Similarity and clustering analysis of communities indicated that similarities of insects in each different community had significant difference. Changes of insects community diversity are mainly in connection with vegetation type.
