Aeolian activities are known to exist widely in the Tibetan Plateau in historical periods,about which very little research has been done on the middle plateau.In the present work,aeolian deposition of the Amdo Area CR profile in the middle plateau was investigated.Optically Stimulated Luminescence(OSL)dating was used to establish chronology sequence of CR profiles,and the grain size,magnetic susceptibility,calcium carbonate and organic content of the deposits were analysed to reconstruct the aeolian processes for the last 1000 years in the Amdo Area by CR profile.Then,the response to several characteristic climatic periods of the last 1000 years in Tibetan Plateau was discussed.Aeolian activity in Amdo Area during the last 1000 years was found to have experienced 5 stages.About 300 years before 1310,with weak aeolian activity,the profile showed water dynamic action and indicated warm-humid climate.Being a stable transition stage from 1310 to 1660,the climate became warm-humid with weak wind from 1450 to 1570,the aeolian activity further weakened with slight warming.The period from 1660-1890 was with cool-dry climate and strong wind.From 1780-1860 aeolian activity became more intense and responded with the most recent cold events in the little ice age.From 1890-1940,aeolian activity was very weak,entering the warm period of the 20 th century.From 1940,the Aeolian activity strengthened again and the climate became cool-dry,but with much less LIA.The paleo-aeolian depositional record of CR in central Qinghai-Tibet Plateau has a better response to climate change in the last 1000 years,which is consistent with other climate records in different parts of Qinghai-Tibet Plateau.But CR profile cannot completely reflect characteristic climatic events for the last 1000 years.The Medieval Warm Period(until 1310)had good consistency with lacustrine deposits from central,northern and northeastern part of the Qinghai-Tibet.The starting time of the Little Ice Age(1660-1890)is about 200 years later than reflected by the northeastern,western and northen part of the Qinghai-Tibet,and about 150 years later than reflected by the central part of the Qinghai-Tibet.The end time of the Little Ice Age is consistent throughout the whole plateau.The cold event derived from CR profile agreed with the more recent cold event from other records.The starting time of the 20 th century warming period is consistent with other proxy data. Both the warm and wet phase(1890-1940)and the cold and dry period(1940-)showed unanimous agreement with research on the northeastern,western part of the Qinghai-Tibet Plateau.
