【 摘 要 】

In order to study the relationship between the safety of night voyage and the light pollution at sea, based on the theory of system engineering, the safety of night voyage of ships affected by light pollution at sea is analysed from two aspects: the recognisability of ship lights and navigation AIDS and the visual effect of human body. The following conclusions are drawn: Marine light pollution does exist in China, and its pollution sources include at least glare of urban landscape lighting, evanescent light of fishing lighting at sea, direct light of harbour wharf operation area, and intensive mooring lights of ships in harbour and colour highlight lights of bridges. Based on the analysis of optical principle, the brightness contrast and colour contrast of ship lights and navigation AIDS are reduced by light pollution at sea, which has an impact on the safety of night voyage. Analysing by using visual ergonomics principle, light pollution at sea weakens the contrast sensitivity, colour vision function and stereo vision function of the driver's visual effect, and affects the safety of ship's night voyage.
