摘要: 本文采用扫网和样方法对草坪固定样地无脊椎动物群落进行了调查,根据不同种类的营养情况进行了功能群的划分,并采用物种丰富度、Shannon-Wiener指数、Hulbert种间相遇概率、Pielou均匀度指数等四种多样性指数对群落及功能群的物种多样性进行了测度和分析。结果表明:草坪无脊椎动物功能群组成具有一定的垂直分化;不同植被生长情况下功能群的组成及多样性具有一定的差异,但无明显的规律性;各功能群中,捕食寄生性功能群的多样性最高,而植食性功能群的种类、数量最多,但由于个别种数量的异常,其多样性反而较低。植食性功能群与捕食寄生性功能群在多样性、种类数及数量上呈现一定的互为消长关系。

Abstract: Based on surveys of invertebrate communities on an artificial turf by the sweep net and quadrat sampling methods, we divided the species in the invertebrate community into three functional groups according to their trophic level. The species diversities of the community and functional groups were measured by species richness index, Shannon-Wiener index, Hulbert probability of interspecific encounter and Pielou evenness index. Species compositions of the functional groups were also analyzed. The functional groups differed in their vertical distributions. Species diversity and composition of the functional groups were different among plots with different vegetations. The predatory-parasitic group had the highest species diversity in the community, while the phytophagous group had more species and individuals than others, but its species diversity was not high as a result of some species with numerous individuals. There were dynamic relationships in species diversity, species number and individual number between the predatory parasitic group and the phytophagous group.
