Abstract

In this paper, 1850 literatures published in CNKI from 2001 to 2021 are selected as the research objects, and the progress and hot trends of urban heat island research in China in recent two decades are analyzed by using scientometrics and CiteSpace. The results show that; 1) Urban heat island research in China can be roughly divided into three stages, and the number of current literatures remains stable; 2) There are many research institutions but few publications, which are relatively independent and lack of trans-regional, trans-institutional and trans-field collaborative academic community; 3) The research focuses on the causes, research methods, temporal and spatial characteristics and influencing factors of urban heat island; 4) The research trend front focuses on the evaluation index of thermal environment, sponge city, landscape pattern and spatio-temporal pattern, and analyzes and prospects them. Through the analysis and sorting of the above contents, it is expected to provide beneficial enlightenment for the innovation and practical development of urban heat island theory in China.
