中国1∶100万地貌图色彩系统的设计与建库

中国1:100万地貌图的色彩设计是在对中国地貌特征分析研究的基础上,通过中国地貌图物理色彩模型,根据颜色三个基本特征:即色相、亮度和饱和度的不同变化与组合,结合人们对色彩感受的物理与心理特征,对中国1:100万地貌图2 000多个类型的不同色彩进行定量分析,采用现代数字地图印刷技术的C、M、Y、K四色值来构建色彩与地貌类型之间的联系,建立完整的地貌类型色彩库。以此编制的中国1:100万地貌图不仅很好地反映了中国地貌的总体特征,也反映出不同地貌类型之间的差异,该色彩系统可为编制相关专题图提供借鉴。

Design and Establishment of Color System for 1: 1 000 000 Digital Geomorphologic Map of China

Based on analysis and research on regional geomorphologic characteristics and spatial distribution pattern in China,according to the physical color model of geomorphologic map of China,different transformation and combination of three basic features of color（hue,intensity and saturation）,adding people＇s physical or psychological characters into their feeling with color and the quantitative analysis on more than 2000 color types used in 1∶ 1 000 000 geomorphic map of China,this paper establishes a complete color system of geomorphologic types by taking account of the relation between the color value and unique geomorphologic type which is constructed by the four color value（C,M,Y,K） of modern digital map printing technology.The rules of different color value correspond to geomorphologic genesis types.Sea bottom landform using blue color and the color value can change from continental shelf landform to continental slope landform,to marginal sea basin landform,until to abyssal basin landform.Marine landform using blue color;lacustrine landform,blue-green;among fluvial landform,plain and tableland,using green color,and hill and mountain landforms,brown;among arid landform,plain and tableland using light yellow-brown color;hill and mountain landform,dark orange-brown;aeolian landform,yellow;loess landform,soil yellow color;karst landform,dark brown;peri-glacial landform,blue-purple;glacial landform,purple;and volcanic and lava landform using red color,etc.The 1∶ 1 000 000 geomorphic map of China which is achieved based on the above can not only represent general rule of Chinese geomorphology completely,but also the difference among different geomorphologic types.
