《城市居住区规划设计标准》中15分钟生活圈关键指标讨论

Key Indicators of 15-minute Life Circle in the Standard for Urban Residential Area Planning and Design

文章对新颁布执行的《城市居住区规划设计标准》(GB50180-2018)进行了分析。首先,基于我国国情和规范体系的相关要求,通过建立不同密度的指标模型,分析了《城市居住区规划设计标准》(GB50180-2018)规定的15分钟生活圈密度情况。其次,提出了针对15分钟生活圈指标的三个观点:①当前《城市居住区规划设计标准》(GB50180-2018)中规定的居住密度偏高;②15分钟生活圈的建议居住人口规模为3万~7万人,适宜密度为1万~3万人/平方公里;③15分钟生活圈的步行距离宜为800~1100m。

This paper analyzes the text of the newly issued and implemented Standard for Urban Residential Area Planning and Design.Firstly,the different densities of the 15-minute life circle were analyzed by establishing the index model of different densities,based on China's actual conditions and the requirements of the standard system.Then,three viewpoints of the 15-minute life circle index are put forward:the current Standard for Urban Residential Area Planning and Design stipulates an excessive residential density;the recommended population within the 15-minute life circle is 30-70 thousand,and the appropriate density is 10-30 thousand people per sq kilometer;the walking distance of the 15-minute life circle is 800-1100 meters.
