地貌要素在甚小比例尺地势图上的表示

甚小比例尺地势图上的地貌要素常用等高线与分层设色配合表示。在这类地图上,等高线由具有严格数量指标的高程线转化为表示高程带的轮廓线,由表达地貌元素的形态线转化为表达不同地貌类型的形态线。它表现不同地貌类型的基本特征运用了三种方法:以等高线线性组合图形表示;以等高线与地貌符号配合表示;以地貌符号为主表示。

A Geomorphlogic Element is Expressed in the Very Small Scale Landform Map

A geomorphlogic element is expressed usually in the very small scale landform map.with contour line and color gradient. In it, the contour line is turned from an elevation 1 ne which has the rigorous quantitative target into a planimetric line which indicates the elevation zone, and from the line of configuration used to express gremorphic element into the line of configuration used to express different geomorphic form ?Three means are taken to express the mediate feature of different geomorphic types: the linear combination figure of contour line, the cooperation of contour line and geomorphic sign and geomorphic sign.
