因为气候雪线是理论上假想的，故又称理论雪线（theoretical snow line）。
在此基础上研究了我国森林线的空间分布特征及其与多年冻土线、气候雪线的关系。
On that basis, the primary features of spatial distribution of the forest line in China and its relations with the permafrost limits and climatic snowline are discussed.
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。
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.
导致河流、湖泊演变的主要影响因素有气温变化、降水变化及冰川变化、气候雪线变化等。
The main influence factors leading to the changes of rivers and lakes include air temperature change, precipitation change, glacier change and climatic snow line change.
