摘　　要：本文根据郯庐断裂带江苏及邻区第四纪断裂分布、活动性质、活动方式、活动期及活动强度在各段发展的差异,将研究区内划分为三段:安丘—郯城、宿迁—泗洪、庐江—广济段。第四纪晚期以来断裂活动由北往南逐渐减弱,北段活动由西向东迁移,南段由东向西迁移,这些特征对潜在震源区的圈定具有重要意义。This paper divides the study area into three segments:Anqiu-Tancheng,Shuqie- Sihong and Lujang-Guangji based on the destribution,active character and etc.in the Jiangsu segment of the Tanlu fault zone and it's vicinity.Since Quaternary period,the fault activity has been weakened step by step from North to South;the activity removes from western to eastern in the North segment and eastern to western in the South segment.These charactristics are usefull for determining potential source areas.
