【摘要】 在综述阿尔泰山北部过去2 000 a气候变化研究成果的基础上,归纳了文献中所包含气候信息的地理一致性。就气温而言,基于阿尔泰山北部湖芯、树轮和冰芯重建的气温序列真实记录了北半球的重要气候事件,包括罗马最适宜期（0—400年）、黑暗时代冷期（400—600年）、中世纪暖期（800—1200年）、小冰期（1400—1860年）和现代暖期（自1860年以来）。由太阳活动主控的太阳辐射变化是过去2 000 a来阿尔泰山北部气温变化的主导因素,过去150 a来大气CO₂的增加是现代暖期（自1860年以来）升温的主导因素。就降水而言,阿尔泰山北部过去2 000 a的降水变化趋势显示,高降水时段出现在0—450年、600—800年、1050—1300年、1650—1860年,低降水时段出现在450—600年、800—1050年、1300—1650年、1860—2000年。此外,阿尔泰山北部过去2 000 a来气温和降水的组合并不支持所谓的"暖干—冷湿"水热配置模式。更多还原

【Abstract】 This study firstly reviewed the achievements about climate change in the north Altay Mountains over the past 2 000 years,and then summarized the geographical consistency of climate information contained in these documents. Mutil-proxies（ lake cores,tree rings and ice cores） recorded the five important climatic events in the Northern Hemisphere,including the Roman Optimum（ 0-400 AD）,Dark Age Cold Period（ 400-600 AD）,Medieval Warm Period（ 800-1200 AD）,Little Ice Age（ 1400-1860 AD）,and recent warming period（ since 1860 AD）. These climatic events were mainly modulated by solar activity-dominated solar radiation variations in the past2 000 years and recent warming period since 1860 AD,which were largely attributable to an increase of CO₂ concentration in the past 150 years. The precipitation history in the north Altay Mountains over the past 2 000 years indicated that these periods including 0-450,600-800,1050-1300,1650-1860 AD were characterized by high precipitation,and those including 450-600,800-1050,1300-1650,1860-2000 AD were featured by low precipitation. In addition,the combination of temperature and precipitation in the north Altay Mountains over the past 2 000 years did not supported the "cold-wet and warm-dry"hydrothermal configuration in the arid zone in Central Asia.更多还原
