In view of that the Fenghe River water pollution has become more and more serious, nitrogen and organic matter pollution were put forward as the important study targets. Community structure of the microorganisms could reflect the water pollution condition to a certain degree. By investigating the correlation between the water condition changes and the microbial community variation, it make possible to look upon river pollution from different perspectives. By the use of Illumina high-throughout sequencing, we found that the dominant genera were , Comamonadaceae, and in Fenghe River aquatic environment. and which are known as bacteria closely related to human activities, were found to account for larger percentages in the wet season than in the dry season, thus showing that the river was more influenced by anthropogenic activities in the wet season. The water quality was better in the wet season, while the microbial community structure was more stable and the diversity condition was better in the dry season. From the aspect of chemical pollution and microbe, this research helps to carry out planning for protection of drinking water sources and improvement of water environmental condition.
鉴于汾河水质污染日益严重，提出将氮和有机物污染作为重要研究对象。微生物群落结构在一定程度上能够反映水污染状况。通过研究水质变化与微生物群落变化之间的相关性，有望从不同角度审视河流污染问题。利用Illumina高通量测序技术，我们发现汾河水生环境中的优势菌属为Comamonadaceae以及其他菌属。已知与人类活动密切相关的细菌在雨季的占比高于旱季，这表明河流在雨季受人为活动的影响更大。雨季水质较好，而旱季微生物群落结构更稳定，多样性状况更佳。从化学污染和微生物角度来看，本研究有助于开展饮用水源保护规划及改善水环境状况。
