冷与热、干与湿是构成气候差异的基本矛盾。因此气温和降水在空间分布和时间差异上就成为我们通常划分气候类型的基础。《气温曲线与降水柱状图》以横坐标表示月份,纵坐标表示气温和降水的高低与多少,比较具体、形象地表现了一个地区的气候特点。依据这些特点判断所属气候类型,进而分析这种气候类型的成因,找出其分布规律,是学习中学地理的重要内容。因此,指导学生阅读和分析教材中提供的《气温曲线与降水柱状图》判断气候类型,具有比较重要的意义。
Cold and heat, dry and wet are the basic contradictions that make up the climate difference. Therefore, the temperature and precipitation in the spatial distribution and time differences become the basis for our usual division of climate types. “Temperature Curve and Precipitation Histogram” represents the month on the abscissa, and the ordinate represents the level and temperature of the temperature and precipitation. It shows the climate characteristics of a region more concretely and vividly. According to these characteristics to determine the type of climate, and then analyze the causes of this type of climate, to find out its distribution, is an important part of learning the geography of middle school. Therefore, instructing students to read and analyze the “temperature curve and precipitation histogram” provided in the textbook to determine the climate type, has more important significance.
