Spatial Distribution Characteristics,Implementation Methods,and Effectiveness Evaluation of Systematic Micro-Renewal in Urban Areas:A Case Study of"Kun Xiaowei"in Kunshan,Suzhou
Compared to traditional sporadic micro-renewal,systematic micro-renewal more effectively addresses interrelated issues such as environmental quality,public services,and community governance.Using Kunshan's exemplary"Kun Xiaowei"micro-renewal initiative as a case,this article employs nearest neighbor index analysis,standard deviation ellipse analysis,and spatial syntax to examine the overall clustering patterns,spatial association with urban elements,functional structural characteristics,and local site selection logic of micro-renewal projects at both citywide and district levels.The analysis reveals a spatial pattern in"Kun Xiaowei"characterized by"one primary area with multiple secondary areas,each with distinct types",along with a structural distribution of corridor-and road-oriented,multi-point,diverse projects aimed at"filling gaps".These patterns demonstrate a focus on clustering potential areas and promoting integrated development within districts.The article then introduces Kun Xiaowei's systematic implementation approach:"systematic planning,gradual implementation;top-down and lateral coordination;brand-building and extensive promotion."Based on this framework,an evaluation of four representative units was conducted,centered around three primary indicators—physical space,functional types,and cultural ambiance—and six corresponding secondary indicators to assess implementation outcomes.Finally,the article summarizes eight characteristics of systematic micro-renewal:integrality,hierarchy,openness,purposiveness,abruptness,stability,self-organization,and similarity,offering a reference and insights for micro-renewal practices in other regions.
