【英文摘要】The climatic records at seasonal resolution could offer significant insight into climate driving mechanism. This project developed understanding of the transport path of the climatic singals captured in stalagmtes by modern deposition experiments and field monitoring on variables including climate,environment and hydrology for 5 years inside and outside Heshang Cave, Qingjiang Valley, Hubei Province. Based on the work, geochemical records in Heshang speleothems at high resolution since 9000 aBP were obtained, by which the temperature and rainfall of the past 9000 years were reconstructed respectively. The research suggested that Mg/Ca ratio corresponded to the local atmospheric circulation anomaly since 1970, which was sensitive to the global change. Actually, similar anomaly events occurred regularly in the past 530 years and the frequency matched the solar activity, indicating that the solar changes might be the driver of the climate anomalies. The smallest seasonal, interanuual and interdecadal variation of Mg/Ca ratio ocurred during the Holocene Climatic Optimum (5-6 kaBP), predicating a stable climate stage. The quantitative reconstruction of the rainfall in Southern China derived from stalagmite oxygen isotopes demonstrates that the rainfall was 8% higher than present during 6.45-5.0 kaBP, but only 3% and 4% higher during 8.2-6.4 kaBP and 5.0-3.0 kaBP. The temperature variation in the past 9000 years interpreted by P/U indicats that the temperature during Holence Climate Optimum is higher than present by 3-4℃.
