Abstract: In order to provide scientific guidance for soil quality evaluation and optimum management of flower and seedling industry, we investigated the characteristics of soil animal community with different garden plants and various planting periods in Wenjiang District, Chengdu. A total of 10258 soil animals belonging to 26 orders and 78 families were captured in four sampling times. There were significant differences in the taxonomic richness in the plots with different garden plants, generally highest in plots with Loropetalum chinense var. rubrum or Ginkgo biloba and lowest in plot with Zoysia japonica. The taxonomic richness was lower in the plots with different garden plants than the control. Taxonomic richness and abundance of soil fauna in Osmanthus fragrans plot did not change across sampling seasons. The abundance but not taxonomic richness of soil fauna in other plots had obvious seasonal variations. Different garden plants and various planting periods significantly influenced soil faunal diversity indices. Density-group index (DG) and Margalef richness index (D) in G. biloba plot, as well as Shannon diversity index (H) and D index in Z. japonica plot decreased significantly with the increases of planting period. The DG and D indices of soil animals in O. fragrans plot increased significantly with increasing planting period. The indices of soil animal diversity in L. chinense var. rubrum plot did not change regularly with planting period. The DG, D, and H indices were lowest in O. fragrans plot with different planting periods. Results of hierarchical clustering and canonical correlation analyse (CCA) indicated that garden plant species had stronger effects on the habitat than planting period. Responses of soil fauna to various habitats were different, with available P and soil pH having stronger effects on soil fauna. Our results indicated that soil animal community shifted with the changes of garden plant and planting period as well as management and cultivation methods. Excessive human interference and monoculture had negative effects on soil animal community and caused soil degradation.
