Abstract: In view of the current situation about the construction of environmental risk knowledge map for power grid construction, CiteSpace is used to analyze the co-occurrence, clustering, emergence and timing of key words from the aspects of literature publication, scientific research institutions, author co-occurrence and keywords. It is revealed that the overall cooperation network of research institutions is not yet mature, and the research on author cooperation network is more common, but the scarcity of core authors may affect the depth of research. Keyword clustering and bursts are analyzed, indicating research topics and possible future research directions. It is reported that the research focus of environmental risk knowledge map of power grid construction will turn to risk perception and environmental supervision in the future, and the characteristics and evolution trend of environmental risk of power grid construction are deduced.
