Palaeomonsoon Evolution Recorded Through Bibliometric Analysis in China

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.
