| As an important component of the urban green space system,park green space has a positive effect on improving the quality of life of urban residents.For a long time,China’s urban green space construction uses indicators such as per capita green space and green space rate to measure whether green space resources meet the service bottom line requirements.In the specific period of rapid urbanization construction,this guidance method promotes the overall improvement of urban ecology and recreation environment,but it is easy to ignore the spatial difference between per capita distribution and average distribution.With the change of social and economic development goals,traditional non-spatial indicator management methods and centralized and large-scale resource allocation models are likely to cause the lack of park green space resource sharing and social justice,which is difficult to apply to the construction requirements of the current urban park green space.In recent years,with the change of national policies and government functions,the public has paid more attention to the "people-oriented" ideology,and promoted the concept of social fairness and justice in the field of urban public service facilities space layout.Park green space as an important component of public service resources and the basic category of public facilities,research results on accessibility and balance provide a theoretical and methodological reference for the justice evaluation of park green spatial layout.For the above reasons,this paper attempts to review and sort out the relevant theoretical basis of public management,fairness and justice and spatial layout from the perspective of fairness and justice,reviews the current research progress on the justice evaluation of park green space,and analyzes the connotation of justice of park green spatial layout,and then builds the justice evaluation model of spatial layout for park green composed of accessibility(guaranting equal service opportunities for all),spatial justice(resource allocation prioritizes vulnerable groups),and spatial supply and demand balance(focusing on the distribution characteristics of most use needs,and pursuitng of maximum social benefits.Taking Chaoyang District of Beijing as an example,comparing the analysis results of various evaluation levels,the comprehensive analysis of the main reasons for the imbalance of the allocation of park green space resources in Beijing,and the corresponding optimization strategies for the current situation,to promote the construction of park green space by "heavy objects" to the "people-oriented" planning ideas,and to provide a certain reference for achieving the justice.spatial layout of park green space. |
