在中国地理教学中,青藏高原是一个重点内容,关于其气温特点及成因分析是学习中的一个难点,经常困扰着学生。本文试就青藏高原气温特点及成因,做一些探讨。一、青藏高原气温与同纬度平原地区的气温比较青藏高原气温与同纬度平原地区气温相比较低。气温是距地面1.25米~2.0米(国内为1.5米)上的空气温度。青藏高原平均海拔4 000米以上,根据气温随海拔升高而下降(大致每升高100米,气温约下降0.6℃)可知,青藏高原气温低的根本原因就是地势高。
In geography teaching in China, the Qinghai-Tibet Plateau is a key content. The analysis of the characteristics and causes of its temperature is a difficult point in its learning and often plagues its students. This paper tries to make some discussions on the characteristics and causes of temperature in the Qinghai-Tibet Plateau. First, the Qinghai-Tibet Plateau temperature with the same latitude comparison of temperature in the plain Qinghai-Tibet Plateau temperature with the same latitude in the plain low temperature. Air temperature is 1.25 m ~ 2.0 m above ground level (domestic 1.5 m) on the air temperature. The average altitude of the Qinghai-Tibet Plateau is 4,000 meters above sea level. According to the fact that the temperature decreases with altitude (roughly 100 meters per elevation and the temperature drops about 0.6 degrees Celsius), the fundamental reason for the low temperature in the Tibetan Plateau is the high ground.
