中文摘要：

哈巴雪山（5396m）位于横断山脉中北段，与玉龙雪山（5596m）以金沙江相隔，受西南季风影响强烈。在哈巴雪山3100m以上保存第四纪冰川侵蚀与堆积地貌，主要沿哈巴雪山西北脊两侧分布。应用相对地貌法，对比邻近山地尤其是玉龙雪山，将哈巴雪山冰期系列初步划分为：倒数第二次冰期、末次冰期早期和末次冰盛期（LGM）。以哈巴雪山哈巴河谷的冰碛物为研究对象，其末端海拔高度在倒数第二次冰期、末次冰期早期、末次冰盛期分别约为3100m、3500m、3900m。应用TSAM法、MEIM法、CF法计算得出哈巴雪山古雪线高度在倒数第二次冰期、末次冰期早期、末次冰盛期分别为3675m、4000m、4200m。

英文摘要：

The Haba Snow Mountain, which is in the middle north section of Hengduan Mountain range, separa- ted form Yulong Mountains by Jinsha River and is intensively influenced by the southwestern monsoon. Field in- vestigations show that the Quaternary erosion and sediment geomorphology are preserved above 3100m in the main peak of the Haba Snow Mountains and its surrounding areas. Quaternary glacier erosive and depositional landscapes mainly distribute along both sides of the northwest ridge of Haba Snow Mountains. Using relative geomorphologi- cal method, compared to the glacial series of the Yulong Snow Mountain, the Haba glacial series is initially di- vided into three periods, the penultimate glaciation, the early stage of the last glacial cycle and the last glacial maximum （LGM） . This paper take the moraine of Haba valley in Haba Snow Mountain as the object of stud- y. The results of the study take out that the end altitude during the penultimate glaciation, the early stage of the last glacial cycle and the last glacial maximum are 3 100 m, 3 500 m and 3 900 m. The paper use TSAM method, MEIM method, CF method to calculate ancient snow line height. During the penultimate glaciation, the early stage of the last glacial cycle and the last glacial maximum, they are 3 675 m, 4 000 m and 4 200 m.
