Since the 1980s, the research on environmental risk perception has become the focus and hot spot of international scholars. A large number of scholars at home and abroad summarize and analyze the literature of environmental risk perception from the perspective of different disciplines, but it is still difficult to reach a consensus in this research field. In this study, 415 papers related to environmental risk perception published in 19822019 were taken as samples, and the knowledge unit cooccurrence matrix was constructed by SATI software. The matrix was introduced into Ucinet social network analysis software to generate environmental risk perception keyword cooccurrence knowledge map, and SPSS software was used for factor analysis, cluster analysis and multidimensional scale analysis of high frequency keyword dissimilarity matrix. There are nine academic school researches and four knowledge map dimensions of environmental risk perception. According to these, they are divided into two dimensions: “existentialism ” and “constructivism”. Under the multidisciplinary path, the research of environmental risk perception is permeated and intermingled with each other in “conceptual interpretation”, “objective unity” and “theoretical integration”. However, due to the differences and divisions between “existentialism” and “constructivism”, it is difficult to integrate the study of environmental risk perception. According to this, it will provide reference and reflection for the study of environmental risk perception in China.
