| 摘 要： | 基于沉积微生物在河流生态系统物质循环和能量流动中起的重要作用,探讨了其群落结构与环境要素间的关系,采用PLFA谱图法研究了宿迁市大运河不同水体类型中沉积微生物于不同月份的群落结构特点.结果表明:1)同一水环境状况下的河流沉积微生物群落结构具有很强的一致性,且不同采样断面的水质指标是导致不同条件下微生物群落结构之间存在差异的主要原因;2)在同一采样断面,11月的沉积微生物量均高于9月;3)Ⅳ类采样断面沉积微生物群落结构随时间变化,且此变化主要由G-群落所致,而Ⅲ类采样断面沉积微生物群落结构未随时间发生明显改变;植物因子与11月时不同采样断面的沉积微生物群落结构差异较9月时进一步扩大的现象呈对应关系;4)G-/G+因子适合表征营养要素导致的沉积微生物群落结构变化. |

| Abstract: | Based on the important role sediment microorganisms play in material cycle and energy flow of river system,the relationship between sediment microbial community structure and environmental variables was described,and the research on sediments microbial community structure in different water types during different periods was presented using phospholipids fatty acid analysis (PLFA). The results show that the sediments microbial community structures in the same water condition are in sound consistency,and wat... |
