中文摘要	中国东部季风区和西北干旱区分别受控于季风和西风环流, 是全球变化响应的敏感区域.过去50年全球升温, 西北干旱区降水显著增加, 而东部季风区的降水变化不明显.在未来全球继续变暖的情况下, 两个地区降水将如何变化尚不清楚.利用湖北神农架三宝洞和新疆特克斯科桑洞的石笋生长速率记录, 考察它们对降水变化的响应, 研究冰期-间冰期旋回中两地的降水变化及其差异, 为未来气候变暖下的中国降水模型预测提供一个验证实例.研究表明, 500ka以来中国东部季风区和西部干旱区降水呈现冰期-间冰期波动变化, 气温偏高的间冰期降水量大.但是, 中国西北干旱区降水的响应滞后于东部季风区, 指示两地降水对温度变化的响应可能并非完全同步.
英文摘要	The monsoon region of the eastern part of China and the arid region of western part of China are the sensitive areas of global change, which are separately controlled by monsoon and westerly circulation.In the past 50years, due to global warming, the precipitation of the arid region of Northwest China has significantly increased while the precipitation of the monsoon region of the eastern part of China shows no obvious variation.The future trend of two regional precipitations remains uncertain under the conditions of continuous global warming.Based on the speleothem growth rate records from Sanbao Cave, Shennong jia, Hubei, and Kesang Cave, Tekesi County, Xinjiang, we investigate the responses of those records to precipitation and the precipitation variations as well as distinctions of the two regions on glacial-interglacial scale, providing a case for precipitation forecasts from climatic models in future warming in China.It is found that the precipitation of the eastern part of China and the northwestern part of China fluctuate during glaciation-interglaciation, with an abundant precipitation in both two regions during interglacial period, corresponding to higher temperatures.Nevertheless, the precipitation of Northwest China lags behind that of the eastern part of China, implying the correlation between precipitation and temperature of the two regions are probably not completely simultaneous.
