Based on the data of glacier mass balance and equilibrium line altitude,the characteristics of glacier mass balance change and equilibrium line altitude spatial distribution in Svalbard(Arctic),High Asia and Alps were analyzed. The following conclusions can be drawn:(1) Recently,the glacier mass balance is negative frequently,with the maximum average annual negative mass balance in Alps,reaching to-907 mm,followed by Svalbard,-431 mm,and then in High Asia,reaching to-264 mm.(2) The annual amplitudes of the mass balance in Svalbard and High Asia are relatively low,with small annual variation. The annual changing amplitude of the glacier mass balance in Alps is higher,with large annual variation. The glacier mass balance in Svalbard tends to be positive,and that in High Asia and Alps tend to be negative.(3) The glacier equilibrium line altitude in the interior of Svalbard is higher than that in coast. The glacier equilibrium line altitude in High Asia shows a latitudinal zonality,a longitudinal zonality and a regional zonality. The glacier equilibrium line altitude in Alps is mainly controlled by altitude.
