Study on Near-Line Ratios in Different Urban Central Areas——A Case Study of Nanjing
The'near-line ratio'of the street interface is a key quantitative measure of urban landscape and public life.Based on this,this study selects different regional urban central areas in Nanjing City as the main object,and analyzes the characteristics of streets with different road classes and functional types in terms of building near-line ratio through literature analysis,field research,and multi-source data.Research shows that:①Road hierarchy per-spective:The building near-line ratio is higher on the sides of secondary and side roads compared to trunk roads.However,the overall continuity along expressways is insufficient.②Functional perspective:The building near-line ratio is higher in life service streets compared to commercial streets.The ratio is also higher in commercial complexes than in pedestrian streets and business commercial areas.③Spatial characteristics:The building near-line ratio control is applicable to street spaces with rich public activities,higher pedestrian flow,and a high level of commercialization.The typical value range is 55％～80％.④Differentiated control:Differentiated building near-line ratio control is necessary,with a focus on public activity centers,commercial business centers,as well as secondary and side streets in residential areas.⑤ Synergistic management:The building near-line ratios at the neighborhood and lot levels need to be coordinated to ensure the continuity and completeness of the street inter-face through joint implementation of interface management.
