近30年来秦岭南坡与秦岭北坡气温波动变化趋势分析

Trend Analysis of Temperature Variation of Northern and Southern Regions of Qinling Mountains in Recent 30 Years

秦岭南坡地区近30年,温度增加了2.28摄氏度,而秦岭北坡地区增加了约3.37摄氏度。也进一步反映出秦岭北坡地区的温度增加幅度比秦岭南坡地区的温度增加幅度更大一些。秦岭山区南坡和北坡的温度季节性变化十分明显。夏季温度较高,冬季温度基本都较低。从各个季节温度的数值上看,秦岭南坡的温度基本明显高于秦岭北坡的温度。冬季,秦岭南北坡温度基本均不足3℃,春季温度值次之,夏季秦岭南坡温度比秦岭北坡温度高约0.77℃,秋季秦岭南北坡温度处于向冬季过渡期,相对于夏季,温度明显变化,降幅较大。

Abstract：The temperature of southern regions of Qinling Mountains has increased 2.28℃ in recent 30 years, whereas the tem- perature of northern regions has increased 3.37℃, which indicates that the temperature increase of northern regions is larger than that of southern regions. The temperatures of both regions change remarkably with the seasons. The temperatures in summer are comparatively high, and in winter are low, and the temperatures of southern regions are basically higher than those of northern regions. In winter, the difference of temperature change of southern and northern regions is less than 3℃, and temperature of spring takes second place, in summer, the temperature of southern regions is more than 0. 77 ℃. And in au- tumn the temperatures of northern and southern regions of Qinling Mountains is in the transitional period towards winter, and the temperatures obviously decreased compared with summer.
