中文摘要: 东亚季风气候控制下的山地与岛屿冰期历史、冰川规模及其分布规律对深入探讨中国第四纪冰川的发生机制以及全球变化具有重要的科学意义。最新的绝对年代结果显示,中国东部及东亚沿海岛屿山地(包括中国台湾岛,日本本州岛、北海道,朝鲜盖马高原,俄罗斯远东山地等)的冰期启动与消亡时间存在显著差异,但均严格控制在末次冰期范围之内,相当于深海氧同位素阶段(MIS)4至2,冰川的发育规模在末次冰期早中期(MIS3/4)大于末次冰盛期(MIS2)。对研究区各山地和岛屿末次冰期冰川发育的基本特点进行比较后,明确了影响东亚季风影响区冰川作用的主要控制性因素有:气候因素、构造因素、纬度因素和海陆位置等,它们控制着末次冰期冰川的发生、分布与期次。在此控制性因素影响下,东亚低海拔山地不会出现比末次冰期更早的冰川作用。
英文摘要: Research on the timing, extent, and distribution of the late Quaternary glaciation in the East Asia monsoon area is very important for the discussion on the mechanism of the glacier development and global climate change. New absolute ages indicate that there were clear difference of the glacial advancement and retreat in and along the mountains and islands in East Asia, including on the Taiwan Island, in Japan, Hokkaido, Kaema Highlands, and Russian. However, the glacial history was strictly constrained by the last glacial cycle (LGC) corresponding to marine isotope stage (MIS) 4 and the glacial extent during the early stage of the LGC was larger than that of the late stage. Through comparing the characteristics of the glacial action in these mountains and islands, we confirmed the main influencing factors on the glacial development in the study area. The results show that climate, tectonic uplift, latitude, and the location away from the sea affected the onset of glaciation and glacier distribution and sequence in the East Asia monsoon area. According to these conclusions, it is not possible that glaciers advanced earlier than the LGC in the lower altitude mountains of East China.
