南京江北新区街道景观“人群—空间—设施”三维活力分析研究

Three-Dimensional Vitality Analysis of "Crowd Space Facility" Street Landscape on Jiangbei New District of Nanjing

街道景观中的人群活动、空间特性和设施使用情况能反映街道的活力度和受认可度,为城市更新和新区建设中景观的塑造提供参考和思路。以南京江北新区街道景观为研究对象,探究街道人群构成、活动类型以及沿街功能业态分布,借助百度热力图梳理人群活动时空分布,挖掘重要节点空间;利用空间句法研究街道网络空间逻辑,选取整合度、连接度、平均深度等定量指标,梳理街道路网形态特征;通过SD法空间感知评价,为街道空间形态提升、立面更新、绿化彩化等提供数据支撑;通过街道设施满意度分析,梳理街道景观设施要素及重要节点空间的改造需求。最后,提出南京江北新区街道景观的活力塑造策略,相关研究成果能够为开放式新区建设与老区改造中街道景观优化提供新的规划设计分析方法、设计依据与理念。

Crowd activities,spatial characteristics,and facility use in street landscapes can reflect the vitality and recognition of streets and provide references and ideas for shaping landscapes in urban renewal and new district construction.This paper,taking the street landscape of Jiangbei New District in Nanjing as the research object,explores the street crowd’s composition,the type of activity,and the distribution of functional formats along the street.It uses the Baidu heat map to sort out the spatio-temporal distribution of crowd activities and excavate important node spaces.At the same time,this paper uses spatial syntax to study the spatial logic of the street network,selects quantitative indicators such as integration,connection,and average depth,and sorts out the morphological characteristics of the street road network.Through the spatial perception evaluation of the SD method,it provides data support for street spatial form improvement,fa?ade renewal,greening colorization,etc.Furthermore,through the satisfaction analysis of street facilities,the transformation needs of street landscape facilities elements and important node spaces are sorted out.Finally,the author proposes a dynamic shaping strategy for the street landscape in Jiangbei New District,Nanjing,and the relevant research results can provide new planning and design analysis methods,design basis,and concepts for street landscape optimization in the construction of open new areas and the transformation of old districts.
