Taking the research results of China National Knowledge Network (CNKI) from 1998 to 2023 as the data source, with the help of CiteSpace V and VOSviewer digital technology, the knowledge map on the research of China street space is drawn. The visualization technology shows the structure, evolution of street space, and the interrelationship of green vision rate research, and intuitively shows the research hotspot and frontier dynamics of green vision rate of street space in China. Research has learned that before 2017, the green vision rate of street space was in the bud, and then began to develop rapidly. At present, the street space green rate is mainly concentrated in the street roaming, street walkability, measurement method, evaluation index, healing environment, restorative environment, public space security, street image research, VR virtual reality research and green rate, green rate, green rate, etc. Through the visual map analysis of the green vision rate literature in the street space, it shows that the use of new technologies and cross-field integration will become the future research trend.
