成都“北改”背景下城市形态发展研究——以曹家巷三个住区为例

Research on Urban Form Development under the Background of"Northern Reform"in Chengdu:A Case Study of Three Residential Areas in Caojia Lane

成都主城区北部正由增量扩张转向内生存量优化,而曹家巷片区属于成都市“北改”政策中的典型单元,正面临改造更新。文章借助测绘地形图和现场调研,选择曹家巷片区中不同建成年代下的三个地块——工人村、马鞍北路社区、恒大雅苑,为典型案例进行城市形态指标的对比与分析,探寻城市化进程下曹家巷片区城市形态的演变规律。研究发现三个类型住区的形态指标随建成年代呈现一定的规律性变化,研究成果可为制定城市可持续发展与更新策略提供参考依据。

The northern part of the main urban area of Chengdu is shifting from incremental expansion to endogenous stock optimization.Caojia Lane area,a typical unit in the"Northern reform"policy of Chengdu,is facing renovation and renewal.With the help of topographic mapping and field investigation,this paper selects three plots in Caojia Lane area under different construction ages--Workers Village,Ma’an North Road Community and Evergrande Yayuan as typical cases to compare and analyze the urban form indicators and explore the evolution law of Caojia Lane area urban form under the process of urbanization.It is found that the morphological indicators of the three types of residential areas show certain regular changes with the completion years,and the research results can provide a reference for the formulation of urban sustainable development and renewal strategies.
