摘　　要：从土壤侵蚀制图角度探讨黄河峡谷区侵蚀特点及其演化过程。不同地史期侵蚀—堆积轮回遗留下的界线可作为制图中地物定位、地图和信息源套合配准的控制参照。提出分线控制、分层解译提取信息和分步转绘制图的程序。流水线的现代沟谷缘线是决定图斑格局的最基本的特征线。图斑的形状和走线应遵照遥感影像（彩红外航片和ＴＭ卫星影像）特征，按双毫米尺度进行归并综合。The characteristics of soil erosion and its evolution process in the region of Yellow RiverGorge in Shaanxi and Shanxi provinces and Inner Mogolia Autonomous Region are probed into inaccordance with the opinions of soil erosion mapping. The boundaries are remained during variousdenudation-deposition cycles on historical geology in the region should been regarded as the criticalreference and control in directing and locating of points and lines on surface features,coordinating,adjusting and matching with between differ information resources and maps in geometry.The wa-ter way and modern gully lines are important and elementary lines to provide the basic structurepattern and form of the thematic map.The mapping program presented should include that controlusing the different topograph lines,interpretation and extraction of the available information by eachlevels,and carring on the transfaring and mapping step by step.The forms and drawing lines ofsurface feature must follow the characteristics of remote sensing image such as color infrared aerialphotograph and TM,and then are merged into and synthesined in the scale of double millimetres.
