It has been approved that life path and discipline tree techniques developed by time geographers are an effective method to examine academic thoughts and related activity characteristics for scientists, especially for those geographers who have rich time space path and traveling experiences in their lives. The author of this paper considered the technique suitable to observe personal experiences of Professor CHEN Chuan kang (1931～1997), the former vice president of the Geographical Society of China and a faculty of Department of Urban and Environmental Sciences, Peking University who had rich travel records, wide territories of research interests, and plenty of academic writings in his life span of 66 years. On the statistical basis of all his 1212 papers and books, the author firstly analyzed distributions of all works from the temporary dimension, which not only reflected changes of the number of Chen’s works with fluctuant evolutions of modern Chinese society, but also reflected the changes of the academic disciplines themselves. This kind of disciplinary shifts demonstrated both transformation of personal research interests of Professor Chen and transformation of the whole geographical development in China for about fifty years from the 1950s to 1990s. Secondly, using the concept of "discipline tree", the author checked Chen’s personal academic system, from both perspectives of disciplinary territories Chen had touched and evolutional process of these disciplines during Chen’s time, which could figure out an entire landscape of the professional experience of Chen’s creations to scientific knowledge.
