Research on the Spatial Layout of Park Green Space under the Behavioral Patterns of the Elderly—Taking Shijingshan District in Beijing as an Example

At this stage, the mismatch problem of urban park green space among the elderly population in my country is becoming increasingly serious, and it is urgent to explore the high-quality demand of the elderly population for park green space. Therefore, this article takes the park green space in Shijingshan District, Beijing as the research object, constructs a supply and demand evaluation index system for park green space from the perspective of the elderly, uses the CRITIC objective weighting method to weight the evaluation indicators, determines the weight of each indicator in the supply and demand subsystems, introduces the coupling coordination degree model to construct a supply and demand evaluation model for park green space spatial layout, evaluates the rationality of the spatial layout of park green space in Shijingshan District, and puts forward corresponding countermeasures and suggestions.
