Palaeomonsoon Evolution Recorded Through Bibliometric Analysis in China
-
摘要: 本文通过总结2000—2018年中国知网核心数据库的232篇关于冬季风的古气候文献，结合计量学分析，得到冬季风的历史演变及其中存在的问题：大部分的研究认为，亚洲冬季风形成时间基本在8.2~7.4 MaBP，青藏高原的隆升以及我国北方大面积出现的代表冬季风的风尘堆积可能是冬季风形成的重要标志。自冬季风形成至130 kaBP时期冬季风以加强为主，73 kaBP以后得到的冬季风强度演变结论差距较大，甚至相反。总结冬季风的驱动机制研究来看，新生代至第四纪的冬季风以青藏高原的隆升作用影响为主；第四纪至全新世（甚至早至上新世晚期以来）东亚冬季风主要受到冰盖、全球冰量、太阳辐射量等的影响；而全新世以来不同时间尺度影响东亚冬季风的机制不一样，在百年尺度上可能太阳活动的作用越来越重要。Abstract: Through the bibliometric analysis of 232 publications of winter monsoon paleoclimate from CNKI database, the historical evolution of winter monsoon and its problems are summarized. Most researches’ results show that the formation time of winter monsoon was 8.2-7.4 MaBP. The winter monsoon was mainly presented increase before 130 kaBP, and showed large disparity since 73 kaBP, even opposite. The driving mechanism of winter monsoon was also summarized. The winter monsoon from Cenozoic Era to late Pliocene was mainly affected by uplift of Tibetan Plateau, while the winter monsoon was affected by ice sheet, global ice volume, and solar radiation since late Pliocene. The influence mechanism of East Asian winter monsoon on different time scales are various since Holocene. On a century time scale, the solar activity may show greater importance.
