摘 要：The fluvio-lacustrine sequence in the Nihewan Basin is an important archive of Pleistocene climate and environmental changes in northern China,which provides excellent sources of early human settlements in high-latitude East *** a long-term environmental record from the Pleistocene fluvio-lacustrine sequence in this basin is revealed,based on selected major element pairs that are sensitive to paleo-environmental *** reveal a long-term increasing trend in aridification/cooling in the Nihewan Basin since the early *** provides a general setting for early human colonization in high-latitude northern China(around 40°N).The intensified aridification/cooling is envisaged to reduce tree cover and increase open savanna grass ***,in turn,would promote prominent flourishing population and migration of savanna-adapted early humans in the Old ***,the cold/dry climate may have contributed to the evolution and expansion of early humans in the high-latitude northern China,rather than bringing hardship,as is often thought.
