摘要
冰川变化是气候变化的产物 ,但它与气候参数的关系表现出不稳定。本文通过理论分析发现 :对百年以上的冰川进退基本上决定于温度变化 ,与降水的关系不大。对 1 0 1年以内的冰川波动 ,其大范围的总体特征亦基本上决定于温度变化。个别冰川则比较复杂 ,但在冰川上部无消融区的物质平衡基本上决定于降水。
Glacial fluctuation is the result of climatic change, but the relationship between them is not stable. Theoretical analysis in this paper reveals that glacial fluctuation in time scale longer than century is controlled mainly by temperature, it is weak in the relation to precipitation. To glacial fluctuation in time scale shorter than 10 1 years, the general characteristics of glacial fluctuation in larger areas is also determined by temperature. The individual glacial fluctuation is complicated. But, the mass balance in the non melting region of top part of glacial is basically dominated by precipitation.
