摘　　要：利用辽宁地区跨断层资料分析该区域主要断裂现今活动特征。长期数据结果表明,辽宁东北部地区鸭绿江断裂、浑河断裂活动相对稳定,辽宁南部地区金州断裂和西部地区朝阳-北票断裂、大凌河断裂活动相对活跃,其中金州断裂与朝阳-北票断裂活动特征存在一定相似性。2011年日本9.0级地震对金州断裂和朝阳-北票断裂活动均产生明显影响。2015年至今,金州断裂和朝阳-北票断裂的活动水平与其背景水平一致,处于弱活动水平。The present activity characteristics of main faults in Liaoning area are analyzed using cross-fault data.The results of long-term data show that the activities of Yalujiang and Hunhe faults in northeastern Liaoning are relatively stable,and the activities of Jinzhou fault in southern Liaoning and Chaoyang-Beipiao and Dalinghe faults in western Liaoning are relatively active.There is a certain similarity between Jinzhou fault and Chaoyang-Beipiao fault.The 2011 M9.0 earthquake in Japan had a significant impact on the activities of Jinzhou and Chaoyang-Beipiao faults.Since 2015,the activity level of Jinzhou and Chaoyang-Beipiao faults is consistent with its background level and is at a weak activity level.
