On the basis of AMS ~(14)C, color, magnetic susceptibility and geochemistry of lacustrine sediments from the deltaic area in the estuaries where the Hangbu River enters in the Chaohu Lake,we recovered extreme climatic events during the early Holocene (11. 7-7. 5 cal. kaBP) in the Chaohu Region. The result shows that the sedimentary environment was extremely unstable with strong climate changes,including five dry-cold events at 7. 8 cal. kaBP, 8. 6 cal. kaBP, 9. 4 cal. kaBP, 10. 5 cal. kaBP, and 11. 4 cal. kaB, with the dry-cold events at 8. 6 cal. kaBP and 11. 4 cal. kaBP being stronger than the others. The climatic history is comparable with abrupt early Holocene climatic events record in ice cores,stalagmites,and lacustrine sediments elsewhere in China,suggesting that the climatic record preserved in lacustrine sediments in the Chaohu Region is a response the monsoonal climate in the mid-latitude regions of the northern hemisphere.
