Then explore the correlations between the spatial distribution of AOB and soil environment factors. [Methods] MPN-Griess was used to study the distribution of AOB, using Pearson’s correlation analysis relationships between the distri- bution of AOB and soil environment factors. [Results] The distribution of AOB had obvious differences in vegetation communities of wetland in Ebinur Lake. The trend of distribution is that the
