利用高亚洲定位监测冰川平衡线高度数据,对平衡线高度时空分布特征进行了分析.结果表明:高亚洲冰川平衡线高度在空间尺度上具有纬度地带性、经向地带性和区域性的特征.在时间尺度上,高亚洲定位监测冰川平衡线高度呈现不同程度的升高趋势.在天山山区,乌鲁木齐河源1号冰川和Ts.Tuyuksuyskiy冰川的平衡线高度在1960-2013年间,分别增加约116 m、80 m,二者相比,Ts.Tuyuksuyskiy冰川对气候变化的敏感性更高;在阿尔泰山区,No.125(Vodopadniy)冰川、Maliy Aktru冰川和Leviy Aktru冰川在1983-2007年间,平衡线高度变化趋势基本一致,总体都呈升高趋势,其中,Maliy Aktru冰川平衡线高度增幅最大,升高了约142 m;高亚洲定位监测冰川中,1962-2008年间,七一冰川平衡线高度升高速度最快,增幅最大,升高了约264 m,升高速度最为缓慢的是乌鲁木齐河源1号冰川,其增幅最小,升高了约47 m.
The spatial and temporal distribution characteristics of the height of the equilibrium line are analyzed by using the height data of the glacier equilibrium line monitored by high Asia, and the results show that the altitude of the high Asian glacier balance line has latitudinal, meridional and regional characteristics on the spatial scale. On the time scale, the elevation of the glacier balance line in the high position monitoring in Asia shows a rising trend to some extent.In the Tianshan Mountains, the height of the equilibrium line between the Urumqi glacier No. 1 and the Ts. Tuyuksuyskiy glacier increased by about 116 m between 1960 and 2013 , 80 m, the Ts.Tuyuksuyskiy glacier is more sensitive to climate change; in the Altai mountains, No.125 (Vodopadniy) glacier, Maliy Aktru glacier and Leviy Aktru glacier between 1983 and 2007, the equilibrium line height The trends of the glaciers in Maliy Aktru ranged from about 142 m. The height of the glacier in the high-Asian position-monitoring glacier increased from 1962 to 2008, The fastest, the largest increase, an increase of about 264 m, the slowest increase is Urumqi Heyuan No. 1 glacier, the smallest increase, an increase of about 47 m.
