摘　　要：【目的】街景是彰显城市风貌特色的重要载体。【方法】通过解析街景地方性内涵,对街景地方性特征及空间分布进行识别和分析。将街景地方性解析为物理、社会、历史和美学4个特征维度;运用人工智能图像分析和街景大数据,识别上海市徐汇衡复历史风貌区街景地方性特征并做空间映射,分析风貌区街景地方性表达现状。【结果】上海市徐汇衡复历史风貌区内街景地方性特征中:物理维度的围合度整体适中,绿视率和天空可见度处于中低水平;社会维度的安全性整体较高、人本尺度适中,意象性偏弱;历史维度的易读性在风貌区南部较强,中部及西部边界较弱;美学维度的街景视觉丰富度较强、一致性较强,沿街界面渗透性适中。【结论】可为城市更新中街景地方性的保护和优化提供线索,也拓展了城市尺度下空间感知品质的分析与评价思路。[Objective]As one of the major open spaces,urban streets not only carry the transportation function,but also promote social interaction and economic growth,while displaying the aesthetic,cultural and historical characteristics of the city.However,many new or regenrated streets have gradually lost their identity due to the compromise of large-scale construction and short-term delivery.It is important to explore ways to protect and optimize the locality of streetscape since street constituents the most direct impression of a city,which not only forms the identity of a city together with architecture,historical and cultural heritage,geographical characteristics and social life,but also serves as an independent carrier of local expression.The identification and optimization of streetscape locality can help protect the uniqueness of landscape,enhance urban identity and construct urban image,especially for historical and cultural preservation areas in modern cities,and can also work as an important step to retain urban memory and enhance residents'sense of belonging.[Methods]This research first establishes a theoretic framework for streetscape locality through a discussion based on literature reviewed.The research proposes that streetscape locality should include the physical,social,historical and aesthetic aspects,with relevant indicators being identified for the four aspects respectively.These indicators are then compared with streetscape characteristics that can be measured by current image analysis technologies.On this basis,a framework for identification of streetscape locality is constructed.Taking Shanghai Hengfu Historic and Cultural Preservation Area(hereinafter referred to as the“Area”)as an example,the research adopts the semantic segmentation method and an AI-based evaluation model to analyze the locality of the Area,with the specific process being visualized using the Geographic Information System(GIS).The current spatial expression of streetscape locality characteristics in the Area is then discussed
