Heritage tourism is a very important research field of tourism studies. Using the China National Knowledge Infrastructure (CNKI) as data source, this paper analyzes articles from Chinese Core Journals with subject heading of "heritage" and "tourism" in the period of 1979-2011. 832 papers were found to be related with heritage tourism. The analysis suggests that heritage tourism studies in China began in the 1990s and experienced a boom in the past decade. According to theories of bibliometrics, about 30.05% papers were published in 10 journals among all journals investigated and 74 authors focusing on heritage tourism studies published about 41.1% papers. Further analysis indicates that institutions focusing on heritage tourism studies were located at big cities such as Guangzhou, Beijing and in regions with rich heritage resources, e.g., southwest and northeast part of China. As one of the most important symbols for academic publications, keyword indicates the main theme and findings of a research paper. In order to find out the current research interest and progress of heritage tourism studies in China, this study established a database with 3613 keywords extracted from 832 above mentioned papers and analyzed them from the aspects of research object, study place, research method and research topic. The results suggest that heritage types being studied in the discourse of tourism studies in China were diverse and included a range of new and emerging fields such as agricultural heritage, industrial heritage and cultural landscape etc. Intangible heritage has been the hottest topic in heritage tourism studies, which is remarkably different from previous ideas. Among all these 3613 keywords, 451 of them indicate study areas. Further analysis shows that most of studies were limited in studying domestic regions, especially focusing on the upper and middle reaches of the Yangtze River and northeast part of China such as the province of Sichuan, Anhui, Yunnan, etc. Thus studies focusing on overseas regions are mainly literature reviews and introductions of conservation experience with limited number of original studies. In terms of research methods, social studies can be divided into two categories, the normative research and empirical research. Heritage tourism studies in China tend to use empirical analysis and 14.5% of them have used statistical analysis. But it should be mentioned that only 35 keywords, 1% of 3613, related to research methods, indicating that current studies of heritage tourism focused extremely on general analysis of problems and corresponding countermeasures, while neglecting the application of new methods and techniques. About 68.5% keywords related to research topics, covering a wide range of topics. These keywords were categorized into more than ten sets according to their relationship with heritage and tourism. Statistical analysis shows that the number of keywords in the first five sets constitutes the majority. These five sets, namely value and property, tourism development, industrial economy, tourist and community, heritage conservation, indicate the key issues of heritage tourism studies in China. Finally, this study proposes that future studies should pay more attention to subtypes of heritage and do research in a broader study area; researchers should adopt new approaches and technologies such as GIS, social network analysis, etc. Specially-targeted research funds and symposiums can be set up to encourage research on issues such as low-carbon, legislative construction, and heritage discourse in China.
