一、图示分类1.等温线图等温线图是用若干条等温线来表示一个地区气温分布的专题地图。该类图示能帮助学生形象地理解气温分布的空间概念,了解气温递变方向和规律,进而分析各地区气温差异的形成原因。等温线图的类型有地面等温线图、等高面上的等温线图等。地面等温线图主要为1月份与7月份等温线图。2.等降水量线图等降水量线一般是指在地图上将同一时间段降水量相同的各点连接起来的线,由等降水量线组成的地图,就是等降水量线图。等降水
First, the graphic classification 1. Isotherm Isotherm is a number of isotherms to represent the temperature distribution of a thematic map. Such pictograms can help students to understand the concept of spatial distribution of air temperature to understand the direction and law of temperature changes, and then analyze the formation of regional differences in temperature reasons. The type of isotherm map is the isotherm map of the surface, isotherm map of the contour surface, and the like. The ground isotherms mainly for the January and July isotherms. 2. Precipitation line map Precipitation line generally refers to the map in the same period of time the same amount of precipitation points connected to the line, by the precipitation line composed of the map, is the precipitation line map. Other precipitation
