| 英文摘要 | Tooth enamel of mammalian fossils can efficiently preserve the original carbon isotopic composition when they lived. The ungulate fossils, especially equids in the early Early Pleistocene Bajiazui fauna from Qingyang, Gansu are studied. According to the enriched relation of carbon isotopes between mammalian tooth enamel and grass diets, the fractions of C-3 and C-4 plants in this region at that time are reconstructed, which indicates that C-3 grass occupied a dominant position. Because C-3 grass adapts itself to cold and damp climates, our analytic results show that the time of the Bajiazui fauna was in a critical state between a glacial stage beginning and a summer monsoon retreat, and it was a refection to the turning cold event of the global climate at the beginning of the Quaternary.; Tooth enamel of mammalian fossils can efficiently preserve the original carbon isotopic composition when they lived.
