Beijing-Tianjin-Hebei region, which is the most densely populated area and plays an important role in China's regional development strategy, has aroused great concern from scholars. Influenced by the national macro policies, the research hotspots are in continuous evolution. In order to sort out the research hotspots in different periods and the network links between research hotspots, and have a deeper understanding of the research fields, research directions, and research status of scholars in various disciplines, bibliometrics and knowledge map visualized technology are used to examine the quantitative characteristics of literatures, the characteristics of journal and discipline distribution, the co-occurrence network structure map of research institutes, and the research hotspots in different periods and their evolution are summarized as well. In addition, we take the research papers of Beijing, Tianjin and Hebei in the collection of core journals, CSSCI, EI source journals and SCI source journals in CNKI (China National Knowledge Infrastructure) as the object of study. The research suggests that: (1) The number of publications of the Beijing-Tianjin-Hebei study is increasing, mainly in the four majors of economics, geography, sociology, and environmental studies, with geography ranking in the forefront of the volume of papers and journal impact factors; (2) Universities and research institutes located in the Beijing-Tianjin-Hebei region are the main forces of the research, and the co-occurrence network density is 0.0063, indicating that a cooperative network has initially been formed among universities and research institutes, but the degree of contact and cooperation is relatively low, and the research in various fields is relatively independent; (3) The study of Beijing, Tianjin and Hebei has gone through three stages, and the research hotspots at different stages have distinctive characteristics of the times, explaining that the Beijing-Tianjin-Hebei study is closely linked to the national macro policies. Since 2006, three major research directions have been formed: Beijing- Tianjin-Hebei integration and industrial restructuring, regional spatial structure and coordinated development strategies, as well as PM2.5 and atmospheric environment. Xiong'an new district, urban agglomeration, new urbanization, and carbon emissions have become new research hotspots.

A bibliometric analysis was applied in this work to evaluate global scientific production of geographic information system (GIS) papers from 1997 to 2006 in any journal of all the subject categories of the Science Citation Index compiled by Institute for Scientific Information (ISI), Philadelphia, USA. ‘GIS’ and ‘geographic information system’ were used as keywords to search parts of titles, abstracts, or keywords. The published output analysis showed that GIS research steadily increased over the past 10 years and the annual paper production in 2006 was about three times 1997s paper production. There are clear distinctions among author keywords used in publications from the five most productive countries (USA, UK, Canada, Germany and China) in GIS research. Bibliometric methods could quantitatively characterize the development of global scientific production in a specific research field. The analytical results eventually provide several key findings.

We performed a bibliometric analysis of published urbanization research from 1991 to 2009, based on SCI and SSCI database. Our analysis reveals scientific outputs, subject categories and major journals, international collaboration and geographic distribution, and temporal trends in keywords usage in urbanization studies and discusses the relationships between urbanization papers and urbanization rate and offer a substitute demonstration of research advancements, which may be considered as a potential guide for future research. The growth of article outputs has exploded since 1991, along with an increasing collaboration index, references and citations. Environmental sciences, ecology, environmental studies, geography and urban studies were most frequently used subject categories and Landscape and Urban Planning was the most productive journal in urbanization studies. The United States was the largest contributor in global urbanization research, as the USA produced the most independent and collaborative papers. The geographic distribution of urbanization articles overlapped quite well with regions with high economic growth in North America, Europe, and Pacific-Asia. A keywords analysis found the USA and China were otspots , confirmed land-use's significant position and revealed keen interest in ecological and environmental issues in urbanization studies. In general, urbanization research was strongly correlated with the urbanization rate although there were different patterns and underlying processes across different countries. This is the first study to quantify global research trends in urbanization. Our study reveals patterns in scientific outputs and academic collaborations and serves as an alternative way of revealing global research trends in urbanization.
