英文摘要	Although the Cenozoic aridification of the Asian interior was of global significance, the timing of its evolution and the drivers remain controversial. However, knowledge of the spatiotemporal pattern of vegetation evolution can inform our understanding of the aridification process. Here, we integrate 58 pollen records with well-constrained chronologies from across Asia, and use the biomization method to quantitatively reconstruct the Cenozoic evolution of the vegetation. The results reveal the occurrence of desert in Northwest China during similar to 43-35 Ma, indicating a dry climate. After similar to 22 Ma there was a further expansion of desert and steppe in Northwest China, indicating the existence of a permanent arid environment. The aridity was intensified after similar to 8-7 Ma, evidenced by the replacement of forest by steppe and desert. We suggest that the permanent aridification since 22 Ma was related to the uplift of the Tibetan Plateau, and that the enhanced aridification since similar to 8-7 Ma was caused by ongoing global cooling.
