| Abstract: | Pollen records from the Chinese Loess Plateau revealed a detailed history of vegetation variation and associated climate changes
during the last 13.0 ka BP. Before 12.1 ka BP, steppe or desert-steppe vegetation dominated landscape then was replaced by
a coniferous forest under a generally wet climate (12.1–11.0 ka BP). The vegetation was deteriorated into steppe landscape
and further into a desert-steppe landscape between 11.0 and 9.8 ka BP. After a brief episode of a cool and wet climate (9.8–9.6
ka BP), a relatively mild and dry condition prevailed during the early Holocene (9.6–7.6 ka BP). The most favourable climate
of warm and humid period occurred during mid-Holocene (7.6-～4.0 ka BP) marked by forest-steppe landscape and vegetation alternatively
changed between steppe and desert-steppe from ～4.0 to ～1.0 ka BP. |
