在高三一轮复习前,同学们接触等高线地形图较少,所以往往对等高线信息的解读存在一定的困难。本文将借助典型例题,例析等高线地形图的特征、判读、计算、综合应用及地形剖面图等内容,帮助同学们提高对该知识点的掌握程度,增强解题能力。一、等高线地形图上各种地形的判读1.一般地形的判读一般地形包括陆地基本地形和山区局部地形,陆地基本地形有平原、高原、丘陵、山地、盆地等,山区局部地形包括山顶、山脊、山
Before the third year of junior high school, there were fewer topographic maps of the students contacting the contour line, so there was often some difficulty in reading the contour information. In this paper, we will use the typical examples to analyze the features, interpretation, calculation, comprehensive application and topographic profile of the topographic map of the contour to help students improve their mastery of the knowledge and enhance their ability to solve problems. First, the interpretation of various topographic terrain map 1. General Terrain Interpretation General terrain includes the basic terrain of land and mountainous terrain, the basic landform plains, plateaus, hills, mountains, basins, mountain topography, including the top of the mountain Ridges, mountains
