摘　　要：通过对滇东北地区历史地震资料的统计分析,阐述26°~29°N,102°~106°E范围内的滇东北地区的强震时空分布和地震活跃周期特征,研究总结地震活动频度与空间分布的关系,得出研究区域内中强地震在时间上具有周期性、空间上具有成带分布和南北迁移的特点。According to the statistical data of historical earthquakes in Northeast Yunnan, the characteristics of spatial distribution Northeast Yunnan, The characteristics and seismic active period are analyzed in the area of 26° - 29°N, 102° - 106°E in the the frequency of seismic activity and the relationship of of strong earthquakes are presented in periods in time and spatial distribution are studied. zonal distribution in space.
