Abstract: In order for green spaces to better facilitate public health, a summary and analysis of literature on stress relief functions of green spaces was done. The software Citespace was used to conduct a visual analysis of the literature on green space and stress relief in Web of Science and China National Knowledge Infrastructure(CNKI) databases from 2002 to 2022 to sort out the research hotspots and trends. This paper analyzed the types and characteristics of green space, demographic attributes and characteristics, research methods and stress measures, and summarized the progress of research on the impact of green space on stress relief, and put forward the outlook for further research in five aspects: expanding and refining green space, improving research methods and systems, enhancing the scientificity of experiments, increasing the attention to special populations, and promoting cooperation in multiple fields and disciplines.
