Abstract: The field of space-time research has received wide attention in the past few decades. In order to explore the trend and hot issues objectively, a database is set up by the software Histcite, consisting of 2263 related papers included in the database of "Web of Science" from 1999 to 2013 and 78139 indirect papers referenced by the papers in first group. The historical citation relationships and the hot-spot papers, key words, and journals are visualized on the platform of Citespace. At the same time, the citation relationships between the 2263 related papers are also analyzed by Histcite. Some conclusions are drawn as follows: Firstly, the widely cited papers are exploding, with the trend from discussions on the theoretical framework to methods and applications. In detail, after the first widely cited paper, titled as "what about people in regional science" written by H?gerstrand in 1970, appears in the citation tree-rings, there scattered certain other widely cited papers during the 1970s when the theory of time geography was being formed. There appear a few hot-spot papers during the 1980s, including the papers from the field of transportation geography. After the 1990s, with the application of GIS, more and more publications related to the subject of space-time were cited, and the trend became more remarkable after 2000s. The content of studies gradually shifted from description of space-time behavior to the interpretation of it. As T-GIS technology matures, space-time behavior will be used not only as an object to be decrypted, but also as a variable to explain space-time phenomena and social problems, and the value of the application will be gradually revealed. Secondly, the main trends of the papers related to space-time published during 1999-2013 have been discovered, including the integration of space-time framework and GIS, the integration of space-time and travel demand, the impact of internet and mobile technology on spatio-temporal behavior, and the gender differences The potential widely cited but non-mainstream papers are in the field of transportation modeling and sociology. Finally, the key words of hot topics and journals related to space-time are also recognized.

Key words: hot spots of research, knowledge map, progress, space-time, time geography
