Abstract

Abstract

Addressing the issues of low sensitivity to scale and weak applicability in research on urban spatial quality， defining update areas based on spatial quality characteristics at the optimal analysis granularity has become an effective way for urban quality to guide urban renewal. The article selects the historical urban area of Hohhot as the research object， explores the optimal spatial granularity of spatial quality in the historical urban area based on spatial autocorrelation measurement indicators， and identifies the distribution characteristics of spatial quality； guiding the delineation of urban renewal areas based on the spatial differentiation characteristics， differences， and internal influencing mechanisms of the subjective and objective qualities of historical urban areas. The results show that： 1）350~400 m is the optimal spatial granularity for studying the spatial quality of the old city in Hohhot. 2）Based on the objective spatial quality characteristics， the update areas are defined as key renovation， encouraged renovation， general renovation， and reserved areas. Then， the update timing is determined based on the subjective and objective spatial quality matching index， namely the short-term， medium-term， and long-term improvement areas. 3）Identify the type of update area and corresponding update approach based on the impact mechanism of objective built environment indicators on subjective quality. The construction of research technology logic has theoretical and practical significance for delineating update areas， clarifying update timing， and identifying update pathways in the process of spatial planning practice.
