Thinning is an effective management step for sustainable forest development,yet less attention is paid to the restoration of soil microbiota after thinning.In this study,both abundant and rare soil microbial communities(i.e.,bacterial,fungal),were evaluated under various thin-ning treatments in a mixed stand of Cunninghamia lanceo-lata and Sassafras tzumu using MiSeq sequencing.Thinning did not significantly change either abundant or rare bacte-rial and fungal community composition,but affected their alpha diversity.The Shannon-Wiener indexes of rare fungal taxa under medium thinning were significantly lower than in the light thinning(P＜0.05 level).Xanthobacteraceae dominated the abundant bacterial taxa,and Saitozyma and Mortierlla the abundant fungal taxa.The most common rare bacterial taxa varied;there was no prevalent rare fungal taxa under different thinnings.In addition,soil available nitro-gen,total phosphorus,and pH had significant effects on rare bacterial taxa.Nutrients,especially available phosphorus,but not nitrogen,affected abundant and rare soil fungi.The results indicate that soil properties rather than plant factors affect abundant and rare microbial communities in soils of mixed stands.Thinning,through mediating soil properties,influences both abundant and rare bacterial and fungal com-munities in the mixed C.lanceolata and S.tzumu stand.
