Abstract

Abstract:

Wetland plays an irreplaceable role in regional ecosystem, and is the result of a long-term interaction between regional ecological and environmental factors, it is important for maintaining the ecological balance. Based on the Web of Science database and the China National Knowledge Infrastructure (CNKI) database, we analyzed the bibliographic information to gain a high-frequency word co-word matrix, obtained co-occurrence view by using Ucinet and Net draw software, and studied the clustering of keywords, in order to discover wetland soil microbial research trends and hotspots. The results show that: (1) the number of publications about wetland soil microorganisms has basically increased year by year, and has entered a rapid growth stage since 2015; (2) the research contents of wetland soil microorganisms in China and abroad are quite different, foreign countries pay more attention to strengthening wetland protection and ecological restoration of degraded wetlands, while domestic researchers mainly focus on wetland soil microbial diversity and microbial functions; (3) keywords in co-occurrence network visualization, such as Wetland, Phytoremediation and Microbes, and soil microorganisms, soil enzyme activity and microbial biomass carbon, have become the focus of current research to some extent; (4) foreign countries mainly use wetland ecosystems whose habitats have been damaged as research objects, and the research scale is large, involving regions, countries and even the global level; domestic research is carried out on wetland reserves. In the future, it is expected that further research could be conducted in the field of wetland soil microorganism research and environmental protection theory and method.

Key words: wetland soil, microorganisms, bibliometrics, research hotspots, trends
