| Summary: | Based on the research from 2000 to 2020 in China Knowledge Resource Database (CNKI) as the data source, with the help of CiteSpace V and VOSviewer digital technology, a knowledge map is drawn on the number of articles, issuing organizations and keywords of underground space landscape in China. Visualization technology shows the relationship between the structure, evolution, and cooperation of underground space and landscape research, and intuitively shows the research hotspots and frontier dynamics of underground space landscape in China. The experiments results show that the underground space landscape was in its infancy before 2003, and then it began to develop rapidly. At present, underground space landscape research in China mainly focuses on hot spots such as landscape design, urban underground space, and public space. Through the visualized map analysis of the underground space landscape literature, it shows the use of new energy and new technology to create energy-saving underground buildings will become a new research trend.
