Abstract: 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.
