Influence of riverbed in-situ remediation on microbial community in urban rivers

  • 摘要: 采用分子生物学检测方法对实施了河床原位修复的河段进行全面的微生物群落分析。结果表明:河床生态修复后微生物群落结构及多样性发生了明显的变化。从微生物多样性指数来看,河床修复段的下游大于上游;从微生物群落结构来看,上游断面中ε-变形菌纲为最主要的细菌类型,多为致病病原菌,与该采样点周边人口密集而水质 经其他处理有关。经河床原位修复后,下游断面ε-变形菌纲丰度减少,α-变形菌纲和β-变形菌纲成为最优势的类群,其他细菌比例也相对均衡,NH3-N和其他理化指标有所好转,说明微生物载体原位修复措施对城市景观河流黑臭的改善有一定的效果。
