Study on Comprehensive Measurement of Public Green Space Accessibility in Megacity from the Perspective of Social Equity:With the Central Urban Area of Chengdu as an Example
The practical consequences of the mismatch and imbalance between supply and demand of public green space recreation services caused by rapid urbanization have led to an in-depth discussion of the social equity of public green space allocation in the academic community.Taking the central urban area of Chengdu,one of the megacities,as an example,and based on the value position of social equity and the key consideration of life circle construction,this paper measures the accessibility of public green space from three aspects of"supply,traffic,and demand",and comprehensively analyzes the hierarchical distribution relationship of the corresponding community life circle and the correlation with the spatial distribution of different social groups.The study found that the social equity of public green space allocation in the central urban area of Chengdu is generally good.The accessibility level of public green space in the community life circle of the central city is equivalent.From the scale of the central urban area,the accessibility of public green space from the perspective of social equity has an obvious"core-periphery"structure.In this regard,this paper proposes to build social equity on the cognitive basis of the cognition of"conditional equity",and the research object focuses on urban public green space which has a more obvious and important impact on social equity.
