Multi-scale approach analyzing the attributes and organization of UPFs in terms of spatial equality.

Approach and implemented scale	Strengths
Quantity and distribution of UPFs (citywide and district scale)	Drawing an overview and comparison the geographical heterogeneity of UPFs' supply across the city
	Identifying the aggregated and disaggregated manner of UPFs regarding to the uneven distribution within the district
Spatial accessibly of the UPFs (district and sub-district scale)	Analysing the degree of accessibility to UPFs through a sub-district scale
	Understanding the neighboring impact based on the inner autocorrelation of accessibility between adjacent sub-districts
Spatial composition and configuration of UPFs and urban fabric (sub-district and neighborhood scale)	Revealing spatial equality from a design perspective
