摘要
气候雪线的空间分布规律既受高度地带性和纬度地带性限制 ,也受区域性气候的控制。雪线空间格局变化实质上是水热条件变化的反映。本文主要依据我国1 0 6个气象站的气象资料 ,从年均温、年降水量和固态降水率之间的相关函数计算出气候雪线高程 ,进而探讨中国大陆气候雪线的空间分布特征。
The regulars of space distribution of the climatic snowline are both controlled by the changes of altitude and latitude,and by the changes of regional climate.In substance,the changes of setup of climatic snowline in space are a reflection of variations of the hydrothermal condition.According to the climatic data obtained from the 106 weather stations in China,the heights of the climatic snowline have been computed and studied on the basis of the correlatable functions between of the annual mean temperature,the annual precipitation and the rate of solid-state precipitation,and the characteristics of the climatic snowline in the space have been discussed.
