Review of Urban Land Management Based on Bibliometrics

As the carrier of global urbanization, urban land is the basic means of productivity and life of urban residents. Urban land management is of great significance to global climate change mitigation, improving ecological quality, promoting economic development, and ensuring sustainable urban development. At present, although studies on urban land management have accumulated at the global level, the differences in research methods, objectives, and perspectives have led to the fragmentation and confusion of research conclusions. Therefore, it is necessary to review the literature of urban land management, clarify the research contexts, grasp the research progress, and predict the research trends. Bibliometrics, as a quantitative analysis method of literature review analysis, is more comprehensive and objective than relying only on a literature review. It is of great value to grasp the topics and trends of the research field from an overall perspective. In this paper, the Bibliometrix R software package was used to conduct an econometric literature analysis on urban land management from 1979 to 2021, using the Web of Science database. The results showed that: (1) the annual scientific research output and citation frequency in the field of urban land management has generally increased. Combined with the annual change trend of scientific research output, urban land management research can be divided into three stages: the budding period, from 1979 to 1989, the development period, from 1990 to 2008, and the high-yield period, from 2009 to 2021. (2) The 129 countries/regions reviewed differed in their research output, and developed countries showed strong research. The United States, China, and Australia were the top three countries in terms of solo publications and cooperation publications. In addition, among the 16,270 authors, the top three authors were Pradhan, Zhao, and Li. (3) The top three keywords in the field of urban land management were “Management”, “City/Cities” and “Land Use”. The research topics can be divided into three stages. The first stage covers studies with topics of “Management”, “Urbanization” and “GIS”, from 1979 to 2013. From 2014 to 2018, the research topics were gradually enriched by “Urbanization”, “Impact”, “System”, “GIS”, “Management”, “Policy”, “Conservation” and “land”, with a trend towards multidisciplinary and multi-perspective comprehensive analyses. From 2019 to 2021, “Management” and “Climate Change” were the main topics.
