The Heizhugou Cave (28°56'02"N, 103°05'47〃E; 1400m a.s.l.) is located at Leshan, Sichuan Province, Southwest China. This study region lies in the eastern part of the Tibetan Plateau, southwest of Sichuan Basin. It is dominantly influenced by the Asian Summer Monsoon (ASM) whose mean annual rainfall ranges from 700 to 1200mm. The mean annual temperature in the cave is approximately 16℃ with relative humidity close to 100%.A stalagmite (EB1) was collected in the chamber with a total length of about 160mm. This sample is divided into two sections of 0~110mm and 110~160mm but there is no evidence of growth hiatus at the depth of 110mm according to lithology. Besides, the growth rate is stable throughout the entire stalagmite, as is supported by the ~(230)Th dating results.We present a continuous high-resolution (ca.3a) record of ASM evolution from 1375 A.D. to 1810 A.D., roughly corresponding to the period of Little Ice Age (1300~1900A.D.,LIA). This paleoclimate time sequencewas established by 9 precise~(230)Th dates and 160 stable oxygen isotope ratios (delta~18). The dating measurements were conducted by multi-collector inductively coupled plasma spectrometer (MC-ICP-MS) at Institute of Global Environmental Change, Xi 'an Jiaotong University, China with error of 2sigma and delta~(18)O data were run at the Isotope Laboratory of Nanjing Normal University with Finnigan MAT-253 mass spectrometer fitted with a Kiel Carbonate Device accompanied by a standard deviation error of 0.06. The delta~(18)O values of the stalagmite (EB1) vary from -10.37 to -8.58 and its maximum amplitude is close to 2, illustrating sensitive response to regional climate change. The average delta~(18)O values during the periods of1540~1680A.D. and 1780~1810A. D. is negative, implying relatively stronger ASM. And the average delta~(18)O values during the periods of 1375~1540A.D. and 1680~1780 A.D. is positive, implying relatively weaker ASM. The general trend of delta~(18)O record from stalagmite EB1 is temporally consistent with the stalagmite records from the Dongge Cave in Guizhou,the Wanxiang Cave in Gansu and the Jhumar Cave in central India within dating errors. This phenomenon shows that the precipitation in these areas is possibly controlled by the same moisture source. Five strong monsoon oscillations during 1600~1800A.D.(Fig.6 W1~W5)are distinctly registered by the stalagmitedelta~(18)O record from Dongge and Heizhugou caves. The delta~(18)O record of EB 1 also indicates a weak monsoon event in the late 16th and early 17th centuries, which is mirrored in the stalagmite records from Wanxiang, Dongge, and Jhumar caves as well as tree-ring records and historical documents. The delta~(18)O profile of the stalagmite EB1 is positively correlated with Northern Hemisphere temperature while it has an inverse association with the record of Southern Hemisphere summer monsoon. These results indicate that northern high latitude climatic signals possibly couple with the Intertropical Convergence Zone (ITCZ) by the Atlantic Meridional Overturning Circulation (AMOC) over the centennial timescale, and thus influence the global monsoon. Significant 25a and 9a cycles in the EB 1 delta~(18)O sequence is respectively shown by spectral analysis (above the 90% confidence level),equivalent to the 1 la and 22a sunspot cycles, suggesting that solar activities are likely responsible for ASM strength changes on the decadal scale during LIA.
