摘      要：Microbial community structure is afiected by both natural processes and human *** coastal area,anthropegenetic activity can usually lead to the discharge of the effluent from wastewater treatment plant(WWTP)to sea,and thus the water quality chronically turns worse and marine ecosystem becomes *** play key roles in pollutants degradation and ecological restoration;however,there are few studies about how the WWTP effluent disposal influences coastal microbial *** this study,sediment samples were collected from two WWTP effluentreceiving areas(abbreviated as JX and SY)in Hangzhou ***,based on the high-throughput sequencing of 16S rRNA gene,microbial community structure was ***,several statistical analyses were conducted to reveal the microbial community characteristics in response to the effluent *** PCoA,the significant difference of in microbial community structure was determined between JX and SY;using RDA,water COD and temperature,and sediment available phosphate and ammonia nitrogen were identified as the key environmental factors for the community difference;using LDA effect size analysis,the most distinctive microbes were found and their correlations with environmental factors were investigated;and according to detrended beta-nearesttaxon-index,the sediment microbial communities were found to followniche theory.An interesting and important finding was that in SY that received more and toxic COD,many distinctive microbes were related to the groups that were capable of degrading toxic organic *** study provides a clear illustration of eco-environmental deterioration under the long-term human pressure from the view of microbial ecology.
