Abstract:Taking the elderly’s physical, psychological, and social health perceptions as clues, based on the landscape planning theory of “Ternary Theory”, this paper takes outdoor activity spaces for the elderly in 12 communities on Haidian Island as research object, makes quantitative measurements and evaluates on background element, activity element and form element of spatial landscape planning. It aims to realize the benign interaction between the landscape planning of community outdoor activity space and the health of the elderly. Through regression analysis, it is concluded that there is a positive correlation between landscape planning elements and health perception of the elderly. The most affected elements of physical, psychological and social health perception are background element, activity element and form element. In addition, suggestions for optimizing activity elements are proposed from three aspects: historical and cultural landscape, behavioral purpose, and social identity.
