As one of the important components of ecosystem services, urban green space can affect the physical activity of the public, especially the exposure level, accessibility and landscape composition of green space are positively correlated with the health behavior activities of residents. Urban green space has the function of improving residents' mental health, physical condition, social adaptation and moral health. In this paper, we analyzed the clustering of thematic word network, high-frequency and central thematic words and thematic words on the basis of 149 literature data of CNKI website from 2009 to 2024, and summarized the research categories of the main urban green space and their main perspectives. In the future research, we should strengthen the interdisciplinary research, especially with the humanities and social sciences, pay attention to the interaction of urban green space, social economy and public health, explore the multiple mechanisms and modes of the value realization of urban green space, and help the harmony and unity of man, nature and society.
