The climatic change since the Last Glacial Maximum (LGM) period was reconstructed based on the analysis of geochemical characteristics of the aeolian deposits in Gonghe Basin, northeastern Qinghai-Tibetan Plateau, coupled with the ¹⁴C and OSL chronology. The cold and wet climate dominated the region before 21 ka BP, and the climate became very cold and dry in 21~15.82 ka BP, corresponding to the LGM period. From 15.82 to 9.5 ka BP, the regional climate tended to be warm and dry in general. During this period, the cold and dry condition occurred in 14.5~13.6 ka BP and 11.9-9.5 ka BP, implying the Oldest Dryas and Younger Dryas phases, while the relatively warm climate was found in 15.82~14.5 ka BP and 13.6~11.9 ka BP (BøllingAllerød period, B/A period). The warm and humid degree obviously increased between 9.5 and 7.2 ka BP, marking the relatively warm and wet condition. The cold-dry and warm-humid climate fluctuated in 7.2~5.1 ka BP. In 5.1~2.7 ka BP, the degree of warm and wet is relatively stable but it tended to be cold with high moisture since 2.7 ka BP. These changes are coincident with the paleoclimatic records in Qinghai-Tibetan Plateau, reflecting higher consistency in climatic change between Gonghe Basin and Qinghai-Tibetan Plateau.
