摘要: 沙漠化专题图必须包括沙漠化土地现状、成因类型、沙漠化土地区划及沙漠化演变趋势的预测等内容。为此必须收集不同时期的航空相片、地形图、文字资料和统计资料作为编图的基础。在航片判读过程中,必须先为各项主要内容建立判读标志。沙漠化专题图的表示方法可以采用质底法、区域法和分区统计图表法等配合使用,使各类专题内容多层次地表示在地图上。根据内容的主次,可以分别采用不同色相、不同饱和度的颜色;不同形状的符号;不同粗细的线条互相组合叠置,使沙漠化地图的内容丰富而清晰,分布规律明显;图面色彩鲜艳而柔和,层次分明。在资料丰富,沙漠化专题内容研究较深入的情况下,采用系列图的形式更为理想。

Abstract: The contents, such as the present status of land desertification, causal patterns, classification of land desertification and the predict of evolution trends of desertification, must be included into the thermatical map of desertification. Before the compilation, aerial photos of different stages, topographic maps, documentations and statistics data should be collected as the basic elements for compilation the map of desertification. With the interpretation of aerial photo, firstly interpretation signes should be created for each of main contents showing surface features. The indication of the thermatical map of desertification should be composed of the combination use of bottom quality, sgure mark and administrative statistics diagrommes and tables to indicate the specific contents on the map in a multicomponent manner. In consideration of what is primary from what is secondary, different chromatic facies, the colour of different saturablity, the signs with different shapes, and various cru-deness and fineness of lines can be adopted respectively to make the map tobe more understandable and clear. It will be more desirable to use the format of series maps, if necessary data are available and in the case that the studies of the thermatical contents of desertification are well done.
