Accessibility analysis is widely used in urban planning, transportation planning and geography. CiteSpace software is used to comprehensively analyze the research trends of accessibility research from 1990 to 2020, identify the timing characteristics of the number of publications, analyze the co-occurrence of authors, publishers and keywords, and divide the stages of frontier emergence.The results show that the domestic accessibility research can be divided into the initial stage (1990-2001), the rapid development stage (2001-2010), the rapid development stage (2010-2018) and the mature stable stage (2018-present).Domestic accessibility research can be roughly divided into several groups of authors. The mutual citation relationship between the groups of authors is relatively weak, and the academic exchange is relatively weak. In the long run, it is easy to form academic isolation and academic fortress, which is not conducive to the comprehensive and in-depth research and sustainable development of accessibility.There are close academic relations and cooperation between publishing institutions, which is conducive to the comprehensiveness and richness of accessibility research.The comparison of half-life indexes shows that the quality and influence of literature have no obvious correlation with the number of publications.Most of the publishing agencies are located in big cities such as jiangsu, Shanghai, Beijing and wuhan.In recent years, more and more models and methods have been applied to the study of accessibility, involving urban spatial layout, land use, infrastructure construction and other aspects. The study of accessibility is of great significance to the healthy development of urban economy and rational urban planning.The results above can provide reference for the follow-up theoretical research and practical exploration of accessibility in China.
