城市历史街区街巷界面形态的量化方法——以镇江市大龙王巷历史街区为例

Quantitative methodology on the form of lane interface in urban historical districts:taking Dalongwang Historical District of Zhenjiang City for example

针对城市历史街区街巷界面更新过程中传统研究方法的主观局限性,提出了适用于街巷界面形态的量化分析框架,包括多维量化参数的选取与计算方法、数据采集与分析方法。以江苏省镇江市大龙王巷历史街区为例,通过宽高比、界面密度、贴线率三个参数,分别描述了各级街巷在宽高比例、疏密分布、凹凸变化三方面的形态规律与特征,总结出了控制界面形态的参数区间。

In view of the subjective limitations of tradi- tional research methods in the renewal of lanes in historical dis- trlcts, a quantitative analysis framework suitable for the interface form of lanes has been proposed, including the selection and cal- culation methods of multidimensional quantization parameters, and the methods of data collection and analysis. Taking the his- torical district of Dalongwang Lane of Zhenjiang Province, this essay describes the rules and characteristics of the lane form and summarizes the parameter interval of controlling interfere from the perspectives of the proportion of width and height, density and distribution, and the variation of concave and convex.
