Abstract: To understand community structure of the litter invertebrates in urban forests in the Central Temperate Zone and effects of large-area artificial coniferous forests on community diversity of the litter invertebrates, investigation of litter invertebrates was carried out in the Jingyuetan National Forest Park, with a total of 8 630 invertebrate individuals collected, belonging to 18 orders in 6 classes under 3 phyla. Results show that Collembola, Acarina, Hymenoptera, Coleoptera, Lepidoptera larvae, Araneae, Diptera larvae, and Lithobiomorpha were the dominant groups, which accounted for 97.91% of the total individuals collected. No significant differences were found between the litter invertebrate communities in natural secondary forests and in artificial coniferous forests in number of groups, density, Shannon-Wiener diversity index, Pielou evenness index , Simpson dominance index, and density-group index, whereas big differences were between the two kinds of forests in  density of larvae of Pseudoscorpionida, Lithobiomorpha, Thysanoptera and Lepidoptera,and in ratio of Acarina to Collembola in number of individuals. Jaccard similarity index of soil invertebrate was 0.67 in both of the two kinds of forests.
