山谷冰川稳定态时积累区面积比率研究

Study on AAR of Valley Glaciers in the Steady State

探讨山谷冰川稳定状态时积累区面积比率，即ＡＡＲ值的大小，认为冰川物质平衡高程分布、平面形态及冰面坡度沿程变化形式是影响山谷冰川稳定态ＡＡＲ值的主要因素，并获得了山谷冰川稳定态ＡＡＲ值与物质平衡高程分布及平面形态之间的定量关系。

In this paper, the possible values of AAR of valley glaciers with various shapes in the steady state are estimated They are mainly governed by the altitudinal distribution of mass balance, shape factor and variation of surface slope of a glacier The relation between the altitudinal distribution of mass balance, shape factor of a glacial plan view and AAR of a valley glacier in the steady state is acquired The method of AAR for determining an ancient equilibrium line altitude is appropriate for a valley glacier
