In this study, the abundances of 7 nitrogen cycling genes in the sediments from Hangzhou Bay were analyzed along with bacterial and archaeal 16S rRNA abundances as the biomarkers of their densities. The amount of organic matter (OM) and total nitrogen (TN) strongly positively correlated with each other and microbial densities, while total phosphate (TP) and ammonia-nitrogen (NH3–N) did not. Most studied genes were density suppressed, while&amp;nbsp;&lt;em&gt;nirS&lt;/em&gt;&amp;nbsp;was density stable, and&amp;nbsp;&lt;em&gt;nosZ&lt;/em&gt;&amp;nbsp;and&amp;nbsp;&lt;em&gt;hzo&lt;/em&gt;&amp;nbsp;were density irrelevant.
