摘要
本文叙述了利用DTM编制小比例尺地势起伏度图的技术和方法。研究表明，我国地势起伏度随海拔高度的增加而增大，一般山地起伏度在201～600m，丘陵起伏度在76～200m，平原起伏度在20m以下。文中详细介绍了对地势起伏度统计数据的分析与处理，分级指标的确定方法。最后，给出了利用计算机与手工相结合的方法来编制地势起伏度图的途径和制图效果。
In this paper the technology and method of compilation of the relief amplitude map
in srpall scale with DTM data are described. The study shows that in China the higher
altitude. the higher relief. and generally speaking the amplitude in mountainous area is
201~600m, whereas in hilly area 76~200m. and in plain no more than 20m. The pa-
per introduces in detail the procedure of analyses and treatment of relief amplitude statis-
tical data. The method of datermination of classes index is indicated. Finally. the meth-
od and results of compilation of the Relief Amplitude Maps of China with the compu-
ter aided and manual techniques are provided.
