从流域尺度揭示天山北坡冰川变化状况，对下游绿洲地区水资源的合理开发利用具有重要意义。基于多源遥感影像提取天山北坡诸河流域近期冰川边界，结合前期发布的冰川编目及ASTER DEM数据，对该区域冰川面积和物质平衡变化特征进行了分析。结果表明：（1）2015年前后天山北坡共计分布冰川10061条，总面积约4855.85±245.86 km²。1960s—2015年天山北坡国内段冰川面积萎缩速率为0.52%·a^-1±0.06%·a^-1，且近年来呈加速萎缩趋势（0.96%·a^-1±0.88%·a^-1）；1999—2015年天山北坡国外段冰川面积萎缩速率约为0.56%·a^-1±0.31%·a^-1。（2）2000—2020年天山北坡冰川表面高程变化速率约为-0.57±0.01 m·a^-1，冰川物质呈持续亏损态，物质平衡为-0.39±0.04 m w.e.·a^-1。（3）天山北坡东、西段冰川面积和物质平衡变化均存在一定的空间差异性，近十几年间，东段各子流域冰川面积萎缩速率和物质亏损速率均相对较大。

Understanding glacier changes on the north slope of the Tianshan Mountains on the basin scale is critical for the rational development and use of water resources in downstream oases. The recent glacier boundaries on the north slope of the Tianshan Mountains were obtained based on multisource remote sensing images. Combined with the glacier inventory released earlier and ASTER DEM, changes in the glacier area and mass balance in this region were analyzed. The results revealed that: (1) A total of 10061 glaciers were distributed on the north slope of the Tianshan Mountains around 2015, with a total area of 4855.85±245.86 km². The glacier area on the north slope of the Tianshan Mountains in China decreased at a rate of 0.52%·a⁻¹±0.06%·a⁻¹ from 1960s to 2015. Furthermore, an accelerated decreasing trend was observed (0.96%·a⁻¹±0.88%·a⁻¹). The glacier area in the foreign part of the north slope of Tianshan Mountains decreased at a rate of 0.56%·a⁻¹±0.31%·a⁻¹ from 1999 to 2015. (2) The change rate of glacier surface elevation on the north slope of Tianshan Mountains from 2000 to 2020 was −0.57±0.01 m·a⁻¹, and the glacier mass balance was −0.39±0.04 m w.e.·a⁻¹. (3) An obvious spatial difference exists in the changes of glacier area and mass balance in the eastern and western parts of the north slope of Tianshan Mountains, and high decreasing rates of glacier area and mass balance were observed in the eastern part.
