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.
