%X <p>To investigate the bacterial community structure in the rhizosphere soil of common reed（<i>Phragmites australis</i>） in the Lhalu Wetland and its correlation with environmental factors， this study conducted a systematic analysis using soil physicochemical property measurements and 16S rDNA amplicon high-throughput sequencing. A total of 43 586 amplicon sequence variants were obtained， and the annotation results encompassed 64 phyla， 162 classes， 361 orders， 523 families， and 1 039 genera. The results indicated that the dominant bacterial phyla in the reed rhizosphere soil of the Lhalu Wetland were Proteobacteria， Actinobacteriota， and Acidobacteriota， with <i>Sphingomonas</i> being the predominant genus. Correlation analysis revealed that the contents of titanium and total potassium in the soil were the key environmental factors affecting the composition of the reed rhizosphere bacterial community. In summary， the rhizosphere soil of reeds in the Lhalu Wetland is rich in bacterial resources， and elucidating the characteristics of its community structure provides a scientific basis from the perspective of microbial ecology for the conservation and management of the Lhalu Wetland.</p>
