摘　　要：历史地震可靠性检验分析显示,安徽省及邻区M_S5及以上地震完整记录起自1336年,这以前地震记载大部分丢失。近年来,地震和考古部门利用大规模考古和工程开挖契机,编录识别分析了晚第四纪尤其是新石器时代以来构造变形遗迹。结果表明,在皖西南的西周一春秋期和皖北大汶口晚期及豫南东周期文化层中分别发现史前地震遗迹。郯庐断裂带苏皖交界地区段落,自晚更新世以来曾发生数次以斜向平移逆冲为主要方式的快速变形事件,后者得到微观研究方面的证实。研究结果一定程度上弥补了地震史料记载的局限,并丰富了考古和史前地震乃至地震预测的研究方法。Analysis on the reliability test of historical earthquake dislocated that an entire record of Ms5 and larger earthquake is from 1336, most seismic records have been lost before 1336. Recent year, seismic and archaeological departments use the turning to archaeology and engineering excavation a larger scale, catalog recognition analysis the deformation relic since Late Quaternary especially the Neolithic age. The results showed that, some prehistoric earthquake ruins are found respectively in the cultural layer of Western Zhou Dynasty-Spring and Autumn period in southwestern Anhui,Late Dawenkou in northern Anhui and the eastern Zhou Dynasty in southeastern Henan. In the border area of Jiangsu and Anhui of Tancheng- Lujiang fault zone, several times rapid deformation events with diagonal translational thrust as the primary means, have been occurred, since the Late Pleistocene, the latter confirmed by microscopic research. The results of the study a certain extent compensate the limitations of seismic records, and rich in Archaeology and prehistoric earthquakes and earthquake prediction research methods.
