烟田节肢动物群落多样性调查研究

为了解烟田节肢动物群落的组成及稳定性情况，更好地对烟田害虫进行生态控制，在黑龙江烟区选择大庆、富锦、肇州等地烟田对节肢动物多样性进行定期、定点田间调查。调查结果显示，烟田节肢动物种类共有2纲12目43科64种。同时从物种、营养层、功能团水平上对群落的构成及多样性进行了分析，结果表明：在烟田中顶位物种的丰盛度变化不大，而中位物种和基位物种的丰盛度变化明显；种的多样性整体变化幅度最大，种均匀度比较稳定。

Investigation of Arthropod Community Diversity in the Tobacco Fields

In order to understand the composition and stability of arthropod community in the tobacco fields,better to ecological control of pests in the tobacco fields,the diversity of arthropod in the tobacco fields was regular surveyed in Daqing, Fujin, Zhaozhou, etc. in Heilongjiang province. The survey found that arthropod species in the tobacco fields had a total of two classes, 12 orders and 43 families 64 kinds. At the same time from the analysis of species,nutritive layer,functional group level of community and diversity,the results showed that the abundance of species in the tobacco fields changed little at the top position, but the abundance of species changed significantly at the middle and basal position;Overall the species diversity variation amplitude was the biggest,and uniformity of the species was relatively sta-ble.
