城市色彩特色量化提取方法研究——基于对中国20个城市的比较

A QUANTITATIVE EXTRACTION METHOD OF URBAN COLOR CHARACTERISTICS:BASED ON THE COMPARISON OF 20 CHINESE CITIES

为了在城市色彩规划中塑造具有地方特色的色彩风貌,避免“千城一面”的问题,应重视分析城市色彩的现状基调特色。本文从理论层面对遍在色彩、城市色彩基调特色等相关概念进行了梳理,并采用对比研究的方法,基于中国20个城市的现场调查数据和街景地图数据,从现状建筑立面色彩中量化提取出多数城市共有的遍在色谱和各个城市特有的基调特色色谱,并对20个城市的色彩基调特色进行了初步比较。研究表明,以多个城市的遍在色彩入手可以量化提取城市色彩基调特色,划定该城市特有的色彩风貌片区,有助于探讨其色彩特色的形成机制和保护方法,且遍在色彩与色彩基调特色在城市色彩中占有较高比例,对研究和规划城市色彩具有较为重要的参考价值。

To avoid homogenization of urban identity,it is necessary to analyze the current color tone of a city to develop unique color landscape with local characteristics in urban color planning.This paper first analyzes the concepts of prevalent color and color tone from a theoretical level.Then based on the field survey data and street map data of 20 Chinese cities,the paper quantitatively extracts the prevalent color chromatogram common to most cities and the unique basic color chromatogram of each city from the existing building facade colors,and carries out a comparative study on the color tone characteristics of these cities.The findings reveal that,based on the prevalent color of most cities,the characteristics of color tone of a city can be quantitatively extracted,and then the areas with unique color landscape of the city can be demarcated.This method helps to explore the formation mechanisms and protection measures of urban color characteristics.Meanwhile,taking up a high proportion in urban color,the prevalent color and color tone have an important reference value for urban color research and planning.
