查询词典 glaciations

Two major Neoproterozoic glaciations are Marinoan and Sturtian. A number of studies suggested that the Marinoan glaciation terminated about 635 Ma ago, hut the time of its beginning is uncertain.

新元古代末期两次主要的冰期事件是Marinoan冰期和Sturtian冰期，其中Marinoan冰期结束于635Ma；Sturtian冰期可能发生在710~720Ma，已发表的年龄数据限定它在670Ma之前结束。

During Middle-Pleistocene, the height of Qinghai-Xizang Plateau uplift to 3000m high. At the same time, Quaternary maximum glaciations and hypsithermal appeared. The effect of dynamic and thermodynamic of plateau strengthened further and the southwest monsoon became thicker. Southwest monsoon plays an important role in natural environment of China.

It is suggested that the historical factors,including severe bottleneck and subsequent genetic drift during Quatemary glaciations and fragmentation in postglaciation,small population sizeandlow seedling establishment would have contributed to such a population genetic structure in A.yunrumensis.Based on these results,strategies are proposed for the genetic conservation and management of A.yunnanensis

建议对所研究的云南穗花杉全部居群予以保护，特别是对云南西畴和贵州兴义市七舍两个具有相对较高遗传多样性的居群应该优先建立就地保护点，以达到最大限度保存云南穗花杉遗传多样性的目的。

After a study of macroscopic features for the Quaternary glacial vestiges in the Tanzhesi area of the Western Hills of Beijing,the analysis of the appearances and assemblage features of quartz grain surface textures has been carried out for the palaeoglacial deposits of the Guantuoling and Zhaojiatai glaciations.

以北京西山潭柘寺地区第四纪冰川遗迹的宏观特征研究为基础，对管坨岭水期和赵家台冰期的古冰川沉积进行了石英颗粒表面结构形貌组合特征的分析。

Integrating the latest scientific efforts on the history of the Qinghai-Tibet Plateau uplift, river terrace, loess, glaciations, desert and ecology, the interaction between multi-spheres of the East Asia in 1.2~0.6 MaBP are discussed in this paper.

结合近年来黄土、河流阶地、冰冻圈、沙漠、植被等地表各个圈层在1.2～0.6 MaBP青藏高原构造隆升期间环境变化的最新研究成果，综合论述了在此期间青藏高原的隆升对地表其他各个圈层的影响。

Combined with the former studies and dating, it is believed that the area around the Tanggula Pass has experienced four major Pleistocene Glaciations, corresponding to marine isotope stage 2, 3, 4 and 6, respectively, and two Holocene glacial advances （the Neoglaciation and the Little Ice Age）.
