利用地理属性量表的色盲人群地图色彩设计研究

根据地图表达地理属性的量表性质,将地图设色方案分为定性设色、顺序设色和双向设色等3种方式。基于这3种地图设色方式的特点,根据红-绿色盲的光谱特性,设计了一系列实验地图,通过颜色辨识的心理学实验,分析了红-绿色盲的视觉特征,初步揭示出一些针对红-绿色盲人群使用的地图设色原则,为制作红-绿色盲人群使用的地图提供了有效的参考。

Study on Map Color Design for Color Blindness Based on Geographical Attribute Scaling

Lack of study on principles of map design for color blindness leads to no such maps available for the color blindness,which is challenging cartography.Since red-green color-vision impairment takes 95% of the total color blindness,it is important to study on mp color design for those people.Based on characteristics of geographical attribute scaling,three color schemes(qualitative scheme,sequential scheme,diverging scheme) for maps are examined to that purpose.In order to observe features of map color used for red-green color-vision impairment,a series of color maps are made according to spectrum characters of the red-green color-vision impairment,and used for color psychological experiments.From these experiments,a part of principle of map colors used for red-green color-vision impairment is drawn out,which can be a good reference for making such maps.
