Effectiveness analysis of the National Specimen Information Infrastructure (NSII) in supporting scientific research on biodiversity

With the rapid development of biodiversity informatics, more and more open biological data can be used by researchers. Taking an open data platform as an example, analyzing the research hotspots and development trends in the field of biodiversity in China will help biodiversity researchers and policy-makers keep abreast of the current status and trends of biological research, and provide decision support for the construction of biodiversity in China. We searched the full text of the literature in CNKI and Google Scholar from 2013 to 2023 with the relevant search terms of “National Specimen Information Infrastructure (NSII)”, and retrieved a total of 1 070 supported by NSII literature, including journal articles (822), dissertations (233), popular science articles (5), conference articles (6) and reports (4). Through the means and methods of bibliometrics, the 822 journal articles supported by NSII are explored from the aspects of publication status, research topics and hot spots, research institutions, etc., to explore the current status, hot spots and trends of biodiversity research supported by NSII. According to the results obtained from the keyword co-occurrence network map, the research hotspots of biodiversity focus on the analysis and modeling of species distribution, climate change, taxonomy, biodiversity research, and research platform construction. Biodiversity informatics is developing rapidly in China, in the future, it is still necessary to improve data source construction, resource integration, sharing capability, professional competence and international cooperation, etc. to promote the development of biodiversity scientific research continuously.
