Based on the co-word clustering method, this paper analyzes the research frontiers of microclimate in the past ten years at comparison with China and foreign countries, and obtains domestic research focuses: climate adaptation, urban planning and layout, plants, and urban heat island effect, however the foreign research emphases are: simulation study of landscape architecture elements, urban heat island effect, ecosystem service, thermal comfort evaluation system. The comparison of the two research characteristics shows that the domestic research has some deficiencies in contents and methods while making some achievements. Based on the experience of other countries and the overall background of China’s urban development, the future research on China’s microclimate can be in-depth from the following aspects: to create a healthy urban landscape integrating human and ecology; a research approach that promotes multidisciplinary integration.
