Sporo-pollen records from the western part of Chinese Loess Plateau revealed a detailed history of vegetation variation and associated climate changes since 13 ka BP. Before 12.1 ka BP, steppe or desert-steppe vegetation dominated landscape, which was then replaced by a coniferous forest under a generally wet climate (12.1-11.0 ka BP). The vegetation was degenerated into steppe landscape and further into a desert-steppe landscape from 11.0 to 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 an alternation of steppe and desert-steppe has occurred since ~4.0 ka BP.
