摘要： We performed a bibliometric analysis of relevant research trends, based on academic articles about the aquatic microbial community and recorded in the Web of Science during 1991-2018. The number of publications per annum is clearly rising and began to grow rapidly in 2005. Developed countries (e.g. the USA and some European countries) published the most articles, and led international cooperation. International cooperation benefitted from the implementation of the European Union (EU) Water Framework Directive and from the origination and development of molecular biological techniques. A strong correlation existed among such key words as "bacteria", "DGGE" (Denaturing Gradient Gel Electrophoresis), "16S rRNA", "pyrosequencing" and "sediment" as key research directions for many years. Sediment, biofilm and wetland were the main habitats studied; and high-throughput sequencing gradually replaced the traditional DGGE and other technologies, remaining the most popular research method at present. Studies still focus on basic research; interest in microbial community composition, structure, diversity and ecology remains high; and metagenomics and the microbiome have received considerable attention recently. Key words such as "organic matter", "nutrient", "enzyme activity", "nitrification", "denitrification" and "cyanobacteria" indicate current research hotspots, and we suggest this is because increasing attention is paid to environmental protection and management of the water environment by aquatic microorganisms. We predict that future research will promote the ultimate goals of warning about threats to the water environment and restoration by investigating the function of the aquatic microbial community.
