建筑物色彩在城市空间中的衰变规律

Decay Law of Architectural Color in Urban Space

摘要:

分析了空间颜色的衰变理论，包括大气衰变的朗伯定律、粒子散射原理等，并在不同大气能见度、不同观测距离条件下对建筑物色彩的衰变规律进行了实验研究.结果表明：建筑物色彩在城市空间中的衰变符合郎伯定律，亮度和饱和度随着观测距离的增加呈指数规律衰变，并与大气衰变系数有着直接关系，而色相基本保持不变.

Abstract:

This paper presents an analysis of the theory of spatial color decay including Lambert Beer law of atmospheric decay theory, particle scattering theory and so on. By selecting different atmospheric visibilities and various observation distances, an experimental research is conducted on architectural color decay law. The results of research indicate that architectural color decay meets the Lambert Beer law, brightness and saturation decay with the increasing distance of observation in accordance with an exponential law and the decay are directly related to atmospheric decay coefficient, while color hue basically remains unchanged.

Key words:architectural color; spatial color decay; Lambert Beer law; observation distance
