摘要: 本文是用彩色晕渲编制1:1,000.000西宁幅地貌图的制图方法小结.从三方面论述:1.该图采用相互迭置的两层平面表示,第一层面以彩色晕渲表示地貌图上的基本形态成因类型,第二层面以彩色符号加绘彩色晕渲表示不同地貌形态与结构,可以使地貌图更加形象、生动;2.分别介绍平原、台地、丘陵、山地及其内部的个体地貌类型的晕渲塑造方法;3.讨论了电子分色机制版技术复制彩色晕渲图并套印线划版的整个工艺过程.

Abstract: Through mapping of Xining sheet of 1:1,000,000 chinese geomorphic map,three points on the landform coloration can be summarized as follows. 1)A multi-map type,suited by many levels is adapted to explaine a current geomorphic map,because of showing much more geomorphic contents in general.In the Xining sheet of chinese geomorphic map,the two levels are accepted.The first one is that basic form-genetic types in the geomorphic map is explained by landform coloration instead of the technipue of area solid colour.Using different colours present the difference between edogenetic and exogenetic forces in geomorphie formation of the mapping area. As colours are chosen in practic,characters of exogenetie forces are explained by fully using colour pictographs and habits,and then differences between geomorphie types in quantity and degree are shown by different colour steps.When drawing with landform coloration,according to assuming beam light direction a certain colur tone in a certain geomorphic part occurs with dark and bright varying,to show stereo-sense of geomorphology.The second level is that different forms and textures are represented by colour symbols with landform coloration.When drawing the relationships between the two forms and sites should be noted.Comparing with the geomorphic map,expressed by solid colour method,the geomorphic map drawn by landform coloration is much more pitographic and active. 2)Based on what described above,geomorphic analysis about basic types such as,plains,plateforms,hills,low mountain,middle mountain and high mountain,and individual geomorphic subtypes have been executed.Stereo-form drawing method in geomorphic types of all has been also discussed in detail. 3)The print plate with colour-line symbols of landform coloration geomorphic map is drawn by using general mapping techniques and is divided into different printing subplates based upon design requirement.In the mean time,using a more advance electrie color scanner,a geomorphie map by landform coloration is duplicated and a print plate of landform coloration map is completed.Finally,combination of l.ne-drawing plate with landform coloration plate is printed in a suited way,and thus a landform coloration geomorphic map is produced.
