摘　　要：2008年8月，中国科学院天山冰川观测试验站科研人员对阿克苏昆马力克河源地区托木尔峰青冰滩72号冰川（简称72号冰川）进行了大规模综合性野外科考。初步分析8月1-31日水文气象数据表明，8月72号冰川区月平均气温达5.2℃，较同期天山乌鲁木齐河源1号冰川（简称1号冰川）高1.5℃；月降水量54.3mm，较1号冰川少16.2mm；水文点观测到8月冰川融水径流总量为265.2×10^4m^3。较高的气温导致72号冰川消融强烈，末端退缩严重，目前已退缩至海拔3720m处；冰川面积也明显减少，从1964年的7.27km。缩减为2008年的5.52km^2，44a间共减少1.75km^2（0.04km^2／年）。In August 2008, the researchers of Tianshan Glacier Station, CAS took a large-scale comprehensive scientific expedition for the Glacier No. 72, Qingbingtan, Tuomuer Peak which was the headwaters of Kuumalike River in Aksu. Preliminary analysis of hydro-meteorological data from Aug. 1st to 31st showed that the average monthly temperature reached 5.2℃ in August in the area of Glacier No. 72, which was over 1.5℃ compared with the temperature of Glacier No. 1 in the same period, which located at the headwaters of Urumqi River in eastern Tianshan. 54.3 mm month rainfall in Glacier No. 72 area which was less than 16.2 mm in Glacier No. 1 area. According to the date of hydro-logical observation sites, the total amount of glaciers melt water was 265.2×10^4m^3. The higher temperature resulted in strongly melting and seriously Shrink of Glacier No. 72. At present, terminus position above sea level of Glacier No. 72 has shrunk back to 3720 m. From 1964 to 2008, the area of Glacier No. 72 has been significandy reducing, from 7.27 km^2 in 1964 to 5.52 km^2 in 2008. The total area reduced 1.75 km^2 during 44 years（0.04 km^2/a）.
