Coastal lagoon is an important productive ecosystem on the Earth. In this study, we compared microbial community in the sediments between lagoon and surrounding areas, and explored mechanism for the variation of microbial community. As a result, the sediment of surrounding area showed significantly higher organic matter and total nitrogen than that of the lagoon. The linear regression analysis revealed that organic matter and total nitrogen are positively correlated with . Bacterial and fungal PCoA1 showed significantly positive relationships with the relative abundance of , indicating that affects the bacterial and fungal community in the sediments of both the lagoon and surrounding area. ANOSIM analysis demonstrated that there were significant differences in bacterial and fungal community structure in the sediments between the lagoon and surrounding areas. Therefore, organic matter and total nitrogen affect the microbial community structure in the sediments of lagoon and surrounding areas by regulating the abundance of .
海岸泻湖是地球上一个重要的高产生态系统。在本研究中，我们比较了泻湖与周边地区沉积物中的微生物群落，并探讨了微生物群落变化的机制。结果表明，周边地区的沉积物显示出比泻湖沉积物显著更高的有机质和总氮含量。线性回归分析表明，有机质和总氮与……呈正相关。细菌和真菌的主坐标分析1（PCoA1）与……的相对丰度呈显著正相关，表明……影响泻湖和周边地区沉积物中的细菌和真菌群落。相似性分析（ANOSIM）表明，泻湖与周边地区沉积物中的细菌和真菌群落结构存在显著差异。因此，有机质和总氮通过调节……的丰度来影响泻湖和周边地区沉积物中的微生物群落结构。
