To generate the composite record for the last 1860 years from the three stalagmites, we adjusted the d18O offsets to the HY2 (0.2 per mil) and HY3 (1.1 per mil) records on the level of HY1. The HY1 record and the adjusted HY2 and HY3 records were then combined to construct a new record. The new record was composed of: (i) the HY3 record from AD 1308 to the present (adjusted to the level of HY1), (ii) the original HY1 record between AD 760 and 1305, and (iii) the HY2 record between AD 138 and 754 (adjusted to the level of HY1). Finally, the new record was normalized and a composite Huangye d18OR record was generated. ABSTRACT SUPPLIED BY ORIGINATOR: We developed a composite oxygen isotopic record of cave calcite for the last 1860 years based on three stalagmites from the Huangye Cave in eastern Gansu Province, northern China. The d18O values reflect monsoon precipitation changes, with lower d18O values representing higher precipitation and vice versa. Three intervals of high precipitation were identified at AD 138-450, AD 730-1200, and AD 1860-1960. Two intervals of low precipitation occurred at AD 1320-1410 and AD 1530-1860. The reconstructed monsoon precipitation variations correlate well with other records further east in the eastern Yellow River Basin, suggesting synchronous precipitation changes during the late Holocene in the semi-humid region of northern China on decadal to centennial scales. Peak periods of warfare in dynastic transition times, such as at AD 391-420, AD 601-630, AD 1111-1140, AD 1351-1380, and AD 1621-1650, correspond to sharp declines in precipitation or temperature in semi-humid northern China, indicating a strong connection between climatic and societal changes. Our study suggests that climatic deterioration in semi-humid northern China has played an important role in Chinese societal evolution.
