摘　　要：针对目前机场跑道关闭警示装置的灯光颜色没有统一标准,给飞机的起飞降落造成严重影响这一现状,提出给跑道关闭警示装置的灯光颜色制定统一标准是十分必要的。运用Mile理论及其van de Hulst近似计算方法计算不同颜色灯光在雾和霾环境下的传输衰减,并建立雾和霾的衰减模型,仿真分析了不同LED灯光的衰减特性并通过实验进行验证,为跑道关闭警示装置选择符合要求的灯光颜色标准提供理论参考依据。At present the light color of runway closed warning device have no unified standard at the airport, which casued serious effects on aircraft land and taking off, so it is necessary to set unified standard for the light color of runway closed warning device. This paper uses the theory of the Mile and van de Hulst approximate calculation method to calculate different color lights of transmission attenuation in fog and haze environment and to establish the attenuation model of fog and haze, and it presents the simulation analysis about attenuation characteristic of different LED lights, which provides theoretical reference for the runway closed warning device to select light color standard that meets requirements.
