我们提供了来自华北平原钻探岩芯的新花粉数据，这些数据说明了亚洲温带地区在中更新世过渡 (MPT)（约 1.2-0.7Ma）期间植被演化的性质。结果表明，1.7~1.2Ma期间，以封闭的针阔混交林为主。最重要的植被变化事件发生在1.2Ma，此时针叶林减少，蒿科、藜科和禾本科草原显着增加。约0.7Ma，区域森林植被持续退化并被木本草地取代。植被变化模式与MPT的主要气候波动密切相关，并且与中国大型哺乳动物群（>10公斤）的主要周转事件相一致。特别是，超过 50% 的大型哺乳动物物种在森林衰退过程中灭绝；然而，0.7Ma后它们被新的哺乳动物物种取代。植被和动物记录的比较表明，MPT期间北温带森林被草原取代的过程与大型哺乳动物动物群灭绝和物种形成的更替速度加快有关。
We present new pollen data from a drilling core from the North China Plain which illustrate the nature of vegetation evolution in the temperate zone of Asia during an interval containing the Mid-Pleistocene Transition (MPT), ~1.2–0.7 Ma. Results show that, from 1.7–1.2 Ma, closed needle-leaved and broadleaved mixed forest predominated. The most important vegetation change event occurred at 1.2 Ma when there was a decline in coniferous forest and a significant increase inArtemisia, Chenopodiaceae and Poaceae grassland. There was a continued degradation of the regional forest vegetation and its replacement by woody grassland about 0.7 Ma. Patterns of vegetation change correlate closely with the key climate fluctuations of the MPT and coincide with major turnover events of large mammalian fauna (>10 kg) in China. In particular, >50% of large mammalian species became extinct in the course of the forest decline; however, they were replaced by new mammalian species after 0.7 Ma. Comparison of the vegetation and faunal records indicates that the process of forest replacement by grassland in the northern temperate zone during the MPT was associated with an acceleration of the rate of turnover of the large mammalian fauna, in terms of extinction and speciation.
