Abstract: Green space plays an important role in health intervention. Its impact on the health of the human respiratory system is attracting more attention. This paper collects literature in English from 2000 to 2020 in the Web of Science core database to explore the relationship between green space and respiratory health. It applies the bibliometric method to analyze the status of knowledge network relations, and main characteristics of the studies based on aggregation and individuality. It discovers that these two types of studies both lack longitudinal dimension analysis and influential path analysis. Meanwhile, studies at the overall city and town level need to comprehensive measures, and studies focusing on internal spatial unites of cities and towns need pay more attention to micro-features of green space. The paper develops a comprehensive analytical framework for the impact of green space on respiratory health based on the analysis, with proposing analytical subjects, measurements and analytical methods for future studies.
