| 中文摘要 | 横断山区是我国第四纪冰川发育期次较多、古冰川遗迹也最多的地区之一。本文着重介绍了作者近10年来在该区考察中取得的大量新资料,特别是14C年代资料,在此基础上对该区第四纪冰期划分出8期（次）冰期（冰进、间冰阶段）,并进行了对比。作者认为该区冰川具有明显的区域性规律,其与青藏高原抬升有关;横断山区第四纪冰川活动范围可至北纬26°线以北。 |
| 英文摘要 | There are many Quaternary glacial development stages in the Hengduan（Transverse） Mountains, southwestern China, and palaeoglacial remnants of this area are well developed. This paper presents many new data which were obtained from field observations during the past 10 years, of which related 14C age data are vcry valuable. Based on the above data, the Quaternary glacial epoch of the area can be divided into the following from early to later: l) Yajiageng glacial stage of the Middle Pleistocene; 2) Early Hailuogou glacial stage of the Late Plcistocene; 3) Qingshiban interglacial stage of the Late Pleistocene; 4) Late Hailuogou glacial stage of the Late Pleistocene; 5) Zhituoda glacial advance of the Holocene; 6) Dayanwo glacial advance of the Holocene; 7) Hailuogou glacial advance of the Holocene and 8) Glacial advance of the 17th to 19th centuries.Two conclusions are drawn in the end of this paper: 1) Quaternary glaciers were developed first in the Qinghai-Xizang（Tibet）Plateau and its activity then progressively migrated toward the Hengduan Mountains area. This regional regularity corresponds to uplifting of the Qinghai-Xizang Plateau. 2) The southern boundary of the activity of Quaternary glaciers goes as far as north of latitude 26°N. |
