摘      要：Microorganisms are recognized as sensors of external disturbance in freshwater *** this study,sediment samples from regions with strong human activity interference(four sites),moderate human activity interference(five sites) and minor human activity interference(five sites) in Baiyangdian Lake were collected;and their physiological and chemical properties and heavy metals contents were *** structures of bacterial and fungal communities were tested using 16 S ribosomal Ribonucleic Acid(rRNA) and Internal Transcribed Spacer 2(ITS2) high-throughput sequencing *** results indicated that Proteobacteria was the most abundant bacterial ***,Basidiomycota and Ciliophora were the dominant phyla of *** differences of microbial genera among the three regions we re obse rved,especially fungal *** intensified disturbance by human activities,the Simpson and Shannon indices of bacteria significantly *** fungal communities were clustered into three groups in accordance with the different human disturbance *** bacterial communities of sediment samples under moderate and minor human disturbance appeared similar,but different from those under strong human *** analysis indicated that zinc,total phosphorus,copper,and lead were the dominant factors that influenced the bacterial *** and sulfate-reducing bacteria were influenced by pH,nitrate(NO3),and total *** fungal community was significantly affected by total *** study reveals that sediment microbial community structures among different regions of a shallow lake are mainly impacted by human activities.
