Development, Application and Challenges of Set Pair Analysis in Environmental Science from 1989 to 2020: A Bibliometric Review

Set pair analysis is a new intelligent algorithm for dealing with complex uncertain problems, and it widely used in environmental science because of its concise structure scalability results. However, still unclear about the development stage distribution set specific application key areas. Therefore, based on method bibliometrics, this paper studies development, challenges over past 32 years (1989–2020). The found that terms time dimension, process divided into three stages: initial (1989–2011); rapid (2012–2015); steady (2016 to present). In fields, article focuses fields ecology, water resources, atmospheric science. It mainly assessment, diagnosis prediction. particular, partial connection numbers research trend analysis, which plays an important role current also has shortcomings strong subjectivity, imperfect theoretical system, unbalanced at home abroad. Only when these deficiencies are solved, can be further promoted.
