上海城市色彩的空间特征初探

Research on Spatial Characteristics of Shanghai City Color

基于色彩地理学的传统调查方法受限于调研规模和数据处理能力,已无法适应以建成区为主的超大城市的色彩评估工作。以上海全域为研究范围,一是从数据理性角度,利用大数据街景图片,运用计算机学习,总结上海市域城市色彩的色相、明度和艳度,绘制"上海市域色彩地图",分析色彩三要素在上海市域空间分布的结构和特征;二是从历史演进角度,梳理上海城市色彩复杂性和多元性的历史渊源,以及与城市发展建设的关系;三是从社会感性角度,利用网上问卷和游戏软件,全方位了解市民对上海城市色彩的喜好程度和相关问题。以期为认知上海城市色彩现状特征、存在问题和形成过程提供借鉴,也为上海精细化管理背景下的城市色彩规划与管理提供准确科学的城市色彩基础数据库。

The traditional survey method based on color geography,which is limited by the scale of data processing ability,has been unable to adapt to the color assessment of mega-cities with large built-up areas.This paper takes Shanghai as the research scope.Firstly,from the perspective of data rationality,using big data of street view pictures and computer learning,the hue,brightness and saturation of Shanghai urban city color are collected in order to draw a"Shanghai city color map",and the structure and characteristics of the three elements of color spatial distribution in Shanghai city are analyzed.Secondly,from the perspective of historical evolution,the paper combs the historical origin of complexity and diversity of Shanghai’s urban colors,and the relationship with urban development and construction.Thirdly,from the perspective of social sensibility,using online questionnaires and game software,we can fully understand the citizens’preferences and concerns about Shanghai’s urban color.This paper provides references for the recognition of the current characteristics,problems and formation process of Shanghai urban color,and provides an accurate and scientific urban color database for urban color planning.
