Research Status and Perspectives of Stream Macroinvertebrate Based on Bibliometrics

A total of 2416 articles published in the Web of Science core collection database from 2009 to 2018 were analyzed using bibiometric analysis with CiteSpace software. The aim of the study was to make a knowledge map about macroinvertebrate community research in streams to explore the hypotheses that the scientists have been testing most, and to refine the perspectives in this area. The results demonstrated the following: (1) The number of papers published in an macroinvertebrate community in streams was on the growing stage in last ten years, and the main research force was from the United States; (2) Land use and land cover, water quality and biodiversity relating to macroinvertebrate communities were the three most popular research areas in the last ten years; (3) The main scientific hypotheses in the area of macroinvertebrate community in streams that the scientists have been focusing on in last ten years included as: the relationships between macroinvertebrate community and environmental factors, especially water quality; the study of beta diversity by means of comparative analysis; the multiple influences of environmental pressures on macroinvertebrate community; the study of long-term response of macroinvertebrate community to environmental changes; the study of macroinvertebrate community in intermittent rivers; and the study of biological traits of macroinvertebrate community. We comprehensively sorted out research hotspots and evolution paths in stream macroinvertebrate community research, and provided important basis and reference for future in-depth research.
