Abstract: The literature on flower border published from 1981 to 2021 were collected from the CNKI database as the research object. The knowledge map was drawn by CiteSpace scientific knowledge visualization software, and the authors, research institutions, keywords were analyzed in combination with literature analysis, so as to sort out the development and tendency of Chinese flower border research. The results showed that the research stage of Chinese flower border research could be divided into accumulation period （1981—2000）, growth period （2001—2018） and decline period （2019—2021）; the research group was in the situation of “overall dispersion and partial concentration”, and the extensive cooperative relationship between research institutions had not been established; Chinese flower border research could be divided into four aspects： Flower border design concept research, flower border plants research, flower border application research and flower border construction management research, and the relatively stable research system had been formed; the current research on flower border in China mainly focused on the application and plants research under different cities, environments and scenes, and functional flower border with different characteristics such as low maintenance or rainwater regulation. Based on historical background such as urban biodiversity conservation, carbon neutrality and peak carbon dioxide emissions, exchanges and cooperation should be strengthened, and the follow-up study should be carried out from the perspective of multidisciplinary integration.
