Greenspaces provide extensive ecosystem services for urban,while soil microbiome are key components of Urban landscape. In this study, the high-throughput sequencing of 16S rRNA genes was used to analyze soil microbes under five landscape plants in urban green space in order to study the diversity and influencing factors of soil microbes. It was found that the dominant species of soil microbes had high consistency under different urban landscape plants, the advantaged bacteria at phylum level were Proteobacteria, Actinobacteria, Acidobacteria, Chloroflexi, Myxococcota, but with variety in alpha and beta diversity indexes. Moreover, taxonomic convergence was found in archaeal community, which nearly all belonged to ammonia oxidizing archaea. The interactions between different microorganisms were regulated by soil moisture, salt ion concentration as well as pH.
