With the acceleration of urbanization, the urban ecological environment is facing severe challenges. Urban green Spaces, as an important component of the urban ecosystem, play a key role in regulating the climate, purifying the air, alleviating the heat island effect, and promoting the physical and mental health of residents. This paper takes the ecological and health supply and demand relationship of urban green Spaces as the research core. Firstly, it defines the connotation and constituent elements of ecological supply and health demand of urban green Spaces. Then, it constructs a comprehensive evaluation index system including three dimensions: ecological supply, health demand, and supply-demand matching degree, and presents the core evaluation dimensions and index logic through a table. Finally, strategies are proposed from four aspects: layout optimization, functional improvement, policy guarantee, and technological strengthening, providing theoretical support for the construction of healthy cities.
