摘要：
本文通过搜寻公元10世纪冰岛埃尔加(Eldgjá)火山喷发前后(公元932～948年)各地气候冷暖变化的历史文献记录以及树轮记录，重点发掘并考订了中国的历史文献记录，对公元10世纪冰岛埃尔加火山喷发的气候效应，特别是对中国的气候效应进行了分析。综合中国、欧洲和中东以及日本等地的历史文献记录与树轮记录，发现埃尔加火山喷发后的气候变冷集中在公元934～935年和公元939～942年两个时期。公元934～935年的降温可能是欧洲和中东的区域性降温，公元939～942年的降温在全球范围有广泛表现。埃尔加火山喷发开始后直至公元938年，中国出现了区域性的气候变暖，变暖的峰值可能在公元934年。从现有历史文献证据分析，埃尔加火山喷发后中国的降温发生在公元939～942年。初步估计，公元939年到940年冬季(939年12月至940年2月)中国洛阳开封一带相对于公元933～938年的降温幅度可达5℃～8℃。我们对埃尔加火山喷发过程的考订印证了前人的推测：埃尔加火山在3～8年的喷发过程中，可能于公元934年和939年前后各出现一个喷发的高潮。
Abstract:
The climatic impact of the Eldgjá eruption happened in about 934AD in China was investigatedThe relevant historical data，mainly Chinese historical data，as well as the tree ring records were searched and sortedBased on the Chinese，Japanese and European historical records，as well as the tree ring records，we found that climatic cooling occurred at about 934～935AD and 939～942AD following the Eldgjá eruption The cooling of 934～935AD seemed to be regional and limited to Europe and the Middle East，and that of 939～942AD would probably be globalFollowing the Eldgjá eruption until 938AD，regional warming appeared in China with its climax in 934ADNotable cooling appeared in 939～942AD in China By a tentative estimation，the cooling magnitude would be 5～8℃ in the winter of 939/940AD in comparison with the mean winter temperature of 933～938AD in Luoyang Kaifeng area Our investigation supported that the ～934AD Eldgjá eruption would have two climaxes，iethose in about 934AD and 939AD respectively
