驾驶员行车中主要通过视觉获取信息，而色彩是最易被感知的信息。不同区域的草原公路路侧景观色彩差异较大，对驾驶员行车过程中的视觉特性会产生一定影响。基于色彩心理学理论，结合双因素方差分析方法，比较4名驾驶员在两条路侧景观色彩不同的草原公路上眼动指标均值变化规律，得到以下结论：①景观色彩对驾驶员眨眼持续时间、注视持续时间、瞳孔直径和扫视幅度有显著影响；②土黄褐色暖色调色彩环境对驾驶员视觉影响较复杂，使得瞳孔直径和扫视幅度较大，眨眼时间和注视时间较小；青绿的冷色调则表现相反；③连续单调的景观色彩容易对驾驶员造成一定的视觉疲劳。%Drivers mainly through the visual access to information in driving, and color is the most easily per-ceived information. The color difference in different areas of the grassland highway roadside landscape is bigger, the driver’ s visual characteristic will be effected by the color in the process of driving. Based on color psychology theory and combined with the two-factor variance analysis methods, and compared the eye movement indicators of four drivers in two grassland highways that different in roadside landscape color, get the following conclusions:①landscape color have a significant impact on driver’ s blink duration, fixation duration, pupil diameter and scan-ning rate;②the yellow-brown soil warm color environment influence on drivers’ visual is complex, which made the raising pupil diameter and scanning rate and decreasing driver ’ s blink duration and fixation duration; the cool green color has opposite effects;③continuous monotonous landscape color is easily to cause certain visual fatigue to the driver.
