一、等高线地形图(一)等高线地形图的特征1.同一条等高线上的各点等高,并以海平面作为0米。口诀:同线等高。2.等高距(指两条相邻等高线之间的高度差)全图一致。口诀:同图等距。3.两条等高线不相交。因为一般情况下,同一地点不会有两个高度。但在峭壁悬崖处,等高线可以重合。口诀:重叠为崖。4.等高线疏密反映坡度缓陡。等高线稀疏的地方为缓坡,等高线密集的地方为陡坡。口诀:密陡疏缓。5.等高线与山脊线、山谷线垂直相交。等
Topographic Map of Contour (1) Characteristics of Topographic Map of Contour 1. Contour points on the same contour are of the same height, and take sea level as 0 meter. Formula: with the same contour. 2. Contour (referring to the height difference between two adjacent contour lines) the same figure. Formula: the same picture. 3. The two contours do not intersect. Because under normal circumstances, the same place will not have two height. However, cliffs at the cliffs, contour lines can be coincident. Formula: overlap for the cliff. 4 contours reflect the gradient steep slope. Contour sparse place for the gentle slope, contour line for the steep slopes. Formula: dense steep slow. 5. contour lines and ridge lines, valley lines perpendicular to intersect. Wait
