| 摘 要： | 崂山是中国海岸线上的最高峰。研究发现,崂山发育有典型的古冰川侵蚀和堆积地貌,拥有我国东部罕见的冰碛海岸和冰碛扇等地貌类型。更新世期间,崂山至少发育过4次古冰川作用。更新世早期,崂山东部的雪线为60~90 m(现代海拔),崂山及其周围共发育60余条古冰舌,东部的冰舌一直伸入黄海之中。孢粉组合特征说明,崂山在冰期具备形成冰川的气候条件;堆积物粒度曲线显示为冰川成因的沉积特征。研究还发现,中国东部的古冰川遗迹可能大部分被埋藏起来;区域地形特征和当地气候条件是决定雪线高度的关键因素。 |

| Abstract: | Laoshan Mountain is the highest mountain in China coast.Various typical geomorphic features of glarosion,glacial deposition,rare glacial moraine coast and glacial moraine fans in east are well developed in Laoshan Mountain.Well preserved four glacial epochs are identified in Laoshan Mountain.In early Pleistocene,the altitude of snowline ranged from 60 m to 90 m in east.More than sixty paleo-glacial tongues were developed in Laoshan Mountain,some of them which located in east extended into the Yellow Sea.Sporopollen analysis indicates that the climate in Laoshan Mountain is very cold during the ice age.Multi-modal grain-size probability curves of the moraines are the typical characteristics of sediments deposited by glaciation.Regional landforms and climatic conditions are the key factors dominating the altitude of snowline during the ice age. |
