Exploring the Research Lineage and Hot Trends of Aquatic Ecological Assessment in China—A Bibliometric and Visualization Study Based on CiteSpace in Conjunction with VOSviewer
In order to understand the research trends on aquatic ecological assessment,the scientific papers related in CNKI database from 2002 to 2022 were visually reviewed and debated,which was used with bibliometric tools CiteSpace and VOSviewer,and the key points were domestic research situation,hotspots and trends in this field.The results showed that:①The volume of domestic literature on aquatic ecological assessment had shown an overall trend of fluctuating upward,which shown this field had important scientific value.②Domestic research tends to be mature on the whole and the core group of authors had been preliminarily formed,but a strong cooperation network among the scholars had not yet been formed,which limited the improvement of research level to a certain extent.③The main contributors to study aquatic ecological assessment were universities and research institutions,however,the integration among these institutions was insufficient,and cooperation needed to be improved.① The current focus of this research field is the development of aquatic ecological assessment systems appropriate for China's national conditions,including the choice of assessment indicators and the establishment of methods,which involved with theoretical knowledge and research methods from various disciplines.⑤In the future,there are more development space for the indicator role of phytoplankton and other biological groups,the integrity of community structure,and the entropy weighting method.At the same time,the researches will toward subdivision and integration of theory and practice.
