Abstract: Objective Township left-behind residents are the main builders of "Harmonious and Beautiful Village". Therefore, ensuring the residents' physical health is the basis of rural revitalization, and physical health is closely related to physical activity. Most of the existing researches focus on the physical activity in urban green public space, while seldom trying to reveal the relationship between green public space and physical activity in towns and villages.Methods Taking the green public spaces in Dongshu Town, Tai'an City as an example, this research makes a quantitative study on the physical activity demand of left-behind residents in towns and villages, and evaluates the satisfaction and importance of physical activity demand by virtue of the Kano model.Results Township left-behind residents are more concerned about the environmental safety and facilities layout in green public spaces; children have a higher demand for environmental quality, area size and facilities layout; the elderly group has a high demand for environmental safety, walking infrastructure and the distance between the activity site and the place of residence.Conclusion Therefore, in the construction of green public space following the goal of "Harmonious and Beautiful Village", environmental safety and infrastructure should be put in the first place, and the degree of formal beauty needs careful deliberation, so as to improve the physical activity level and health level of residents and provide basis and reference for further construction of "Harmonious and Beautiful Village".
