Abstract

In the era of post-modernization, profound transformations in urban spaces have
led to significant shifts in the spatial composition paradigms of contemporary urban
heritage. Research on this process is crucial for elucidating the spatial pathways and
compositional changes in the modernization transformation of urban heritage. This
study aims to establish identification indicators and assessment systems for the spatial
