大庆园林植物节肢动物群落多样性研究

Investigation and Analysis of Garden Plant Arthropod Community Diversity in Daqing

为了更好地研究和利用园林植物天敌,对园林植物害虫进行综合治理,对大庆园林植物节肢动物多样性进行调查。结果表明,大庆地区园林植物节肢动物群落顶位物种和中位物种的丰盛度均低于基位物种的丰盛度。营养层在0.20～0.98,种多样性在1.91～3.04,功能团在2.11～3.37,种的均匀度变化不大,在0.81～1.13。

In order to study and use the natural enemy to realize integrated control of the garden plants, the community diversity of arthropod on the garden plants in Daqing was investigated. The top species and median abundance were lower than the base species abundance of arthropod. The diversity index of nutrition layer is between 0.20 to 0.98, it of community diversity is between 1.91 to 3.04, and it of functions group is between 2.11 to 3.37. There was little change in the species degree of homogeneity between 0.81 to 1.13.
