Research Progress of Urban Wind and Thermal Environment Based on CiteSpace and China National Knowledge Infrastructure Database

Abstract

The urban wind–thermal environment affects the sustainable development of the urban ecological environment. In recent years, China has frequently suffered from storms, hurricanes, floods, and other disasters that damage the urban ecology. The urban wind and thermal environment involves many components; therefore, it is necessary to systematically review the current research progress in China. This paper uses CiteSpace software to analyze researchers, institutions, keywords, and research hotspots. By summarizing the knowledge structure, temporal and spatial distribution, evolution trends, and frontiers and hotspots of urban wind and thermal environment research, it is found that (1) the urban wind and thermal environment has gradually become a research hotspot in the field of the urban ecological environment; (2) the cooperative relationship between authors generally presents the characteristics of “large dispersion, small aggregation”, and the inter-institutional cooperation in this field is close and forms part of the interdisciplinary cooperation; (3) the research content involves a variety of disciplines and provides a good platform for interdisciplinary research, and the focus of the research has gradually shifted from the macro urban layout to the micro urban local environment; and (4) in order to obtain a more targeted understanding of the mechanisms of the urban wind–thermal environment, technical methods and regulatory means should be used to study the target at different scales and levels. In the future, multidisciplinary communication should be strengthened, qualitative and quantitative research should be performed with the help of mature technical methods in various disciplines, and the scale classification of research objects should be refined to improve the theoretical methods and evaluation system of each scale.
