| 英文摘要 | Aims Non-native trees are widely used to prevent soil erosion in the Loess Plateau. We aim to investigate the effects of non-native tree plantations on the communities of understory plants and soil macroinvertebrates. Methods The soil, understory plants and soil macroinvertebrates were sampled in non-native Robinia pseudoacacia (RP) and Populus xcanadensis (PC) stands, and native Armeniaca sibirica (AS) stands. Results Abundance and richness of understory plants were significantly greatest in the RP stands. The macroinvertebrates collected belonged to 13 orders across all stands. At the community level, richness did not differ among the stand types, but the abundance was significantly greatest in the PC stands. At the functional group level, phytophages and detritivores preferred the PC stands, whereas predators preferred the RP stands. The generalist macroinvertebrate abundance was significantly greatest in the PC stands. Moreover, the community composition of understory plants clearly differed among the stand types; that of soil macroinvertebrates in the PC stands was separated from the other stand types, which was mediated by environmental variables, especially the soil temperature and soil organic carbon. Conclusions Non-native tree plantations had positive effects on the overall abundance of understory plants and soil macroinvertebrates, but their effects on functional groups were inconsistent, associated with tree identity. The selection of non-native tree should be considered in term of multiple trophic levels, if afforestation has biodiversity objectives. |
