摘要：为探讨表流湿地细菌群落结构的空间分布以及细菌环境影响因子,采用高通量测序方法,对表流湿地沿水流方向10个不同处理单元细菌群落结构进行分析,并利用冗余分析对其与环境因子的关系进行了探究.研究表明:细菌群落多样性指数(香农-威纳指数)平均值为6.57,细菌群落主要属于Proteobacterice(38.97%)、Bacteroidetes(15.63%)等18个门类,丰度大于1%的共有22个属;沿程细菌多样性总体呈现先升高后降低的波动性变化,最终处理单元与最初处理单元的多样性均较其余各处理单元低;细菌丰度与pH、ORP、NH_4^+-N、NO_2^--N、TN均有相关性.
Employing high-throughput sequencing as the method,this study analyzed the relationship between the water environment and the microbial community structure in the surface-flow constructed wetland. The results showed that： the mean Shannon-Wiener index was 6. 57 and there were mainly 18 categories in the microbial community,including Proteobacterice（ 38. 97%）,Bacteroidetes（ 15. 63%） etc. Of these,the total content of 22 genera was over 1%. The microbial biodiversity showed an increasing trend at the beginning and then turned to a decreasing trend in the flowing direction. The results also revealed that pH,ORP,NH4^＋-N,NO2^--N and TN acted as important restricting factors for the microbial community.
