摘　　要：根据地震活动的空间分布、强震的震害影响场及构造能流图象分析结果 ,提出了龙陵 澜沧构造带的分段结果 ,并通过带内地震迁移规律 ,对 1988年耿马 7 2级地震后未来地震活动趋势作了初步估计 :永德及其北西地区和澜沧及其南东地区存在发生 7级及 7级以上地震的可能性 ,下次大震可能将发生于永德地区或其北西更远的地区。According to the analysis of the spacial distribution of seismicity, the affecting field of strong earthquake damage and the tectonic flux pattern, the Longling Lancang tectonic zone is segmented. And the future seismicity trend after the Gengma earthquake with magnitude 7 2 in 1998 is estimated basing upon the earthquake migration law in this zone. We think that an earthquake with M≥7 probably will take place in Yonde and its northwest region, Lancang and its southeast region. And the next large earthquake will possible occur in Yongde and its northwest farther region.
