| 摘 要： | 通过高通量测序和qPCR技术对象山港4种典型生境(牡蛎养殖区OA、海带养殖区SA、自然岛礁区NR、人工鱼礁区AR)和对照区CK的沉积物反硝化细菌丰度和群落结构进行了测定分析,并探讨了反硝化细菌群落与环境因子之间的相关关系。结果表明:沉积物nirK型反硝化细菌丰度在5种生境间没有显著性差异,而沉积物nirS型反硝化细菌丰度排序为AR

| Abstract: | We measured the abundance and community structure of denitrifying bacteria in sedi-ments in four typical habitats(oyster aquaculture area(OA),seagrass aquaculture area(SA),natural island reef(NR),artificial reef(AR))and control habitat(CK,a natural sediment-laden harbor site)of Xiangshan Bay using high-throughput sequencing and qPCR techniques.We further analyzed the correlations between denitrifying bacterial communities and abiotic factors.The results showed that the abundances of nirK-type denitrifying bacteria didn’t differ among those five habitats and that the abundance of nirS-type denitrifying bacteria was the lowest in the AR habitat.The abundance order of nirS-type denitrifying bacteria in sediments was AR
