文摘内容 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.
