摘　　要：城市建筑色彩对城市空间品质塑造具有重要意义。为精细化提升建成区色彩环境品质,突出规划方法的可操作性,运用街景采集与语义分割技术,以南京市浦口老城核心区凤凰大街为研究对象,依据孟塞尔颜色系统及色彩心理学,对研究区域建筑色彩的色相、明度、彩度3个属性进行定量分析,并从整体协调度与单体协调度2个尺度进行建筑色彩品质分析。结果表明:(1)凤凰大街的建筑立面色彩协调度存在较大波动;大街东侧建筑立面色彩协调度在整体与单体两个层面的稳定性都高于西侧;综合2个层面的色彩协调度的分析结果,共筛选出13组需要进行色彩更新的建筑;(2)在原生色谱基础上设计引导色谱,对其进行色彩更新,可以有效提升街道建筑色彩的品质;(3)色彩协调度指标能够作为小尺度色彩更新的有效抓手。不仅可以判断建筑色彩组合的协调性,还能够从点到面精细识别色彩更新对象,量化色彩选择区间,结合原生色谱与设计色谱指导重构建筑色彩的配色方案、调整配色比例,制定具有适应性的色彩方案并落实在空间中。Urban building colors play a significant role in shaping the quality of urban spaces.To refine and enhance the color environment quality of built-up areas and emphasize the operability of planning methods,this study employs street view collection and semantic segmentation technology,focusing on Fenghuang Street,the core area of Pukou Old Town in Nanjing.Based on the Munsell color system and color psychology,the study conducts a quantitative analysis of the hue,value,and chroma attributes of building colors in the research area.The analysis assesses building color quality from two scales:overall harmony and individual harmony.The results show that:①there is considerable fluctuation in the color harmony values of building facades on Fenghuang Street;the color harmony stability of building facades on the east side of the street is higher at both the overall and individual levels compared to the west side.By integrating the analysis results of color harmony values at both levels,13 groups of buildings were identified as needing color updates;②guiding the color update based on the original color palette can effectively enhance the quality of street building colors;③the color harmony index can serve as an effective tool for small-scale color updates.It not only assesses the harmony of building color combinations but also identifies color update targets from point to surface.The range of color choices is quantified.The reconstruction of building color schemes and adjustment of color proportions are guided by integrating the original and design color palettes.This enables the development of adaptable color schemes that can be implemented in space.
