天空蓝色饱和程度与城市空气质量等级的相关性

以大气散射理论为基础,结合颜色学、大气环境监测及城市空气质量日报等相关原理,从理论分析与实证研究2个方面证实了天空蓝色饱和程度与城市空气质量等级之间存在着显著的负相关性,即:天空蓝色饱和程度越低,空气污染等级越高,空气质量状况越差;天空蓝色饱和程度越高,空气污染等级较低,空气质量状况越好;通过相关及回归分析与检验,制得“城市空气质量等级目测色卡”,适用于晴朗天气肉眼观察天空颜色,进而目测估计空气质量等级状况,以采取必要防护措施。

Correlation Between Air Blue Saturation and the Air Pollution Grade of Cities

Based on atmospheric scattering theory,color science,atmospheric environmental monitoring and urban air quality daily reports and other related principles,the negative correlation between air bule saturation and urban air quality level was proved with the theoretical analysis and empirical research.The result showed the lower the sky buh saturation level,the higher the air pollution levle and the worse the air quality.While the higher the sky blue saturation level,the lower the air pollution level and the better the air quality.Through correlation and regression analysis and testing,and an urban air quality grade visual color card was produced.The card can be used to estimate the grade of air quality by observating the fine sky color with the naked eyes.
