摘　　要：针对地震活动相关性分析的实际需要,提出了一种定量分析不同区域地震活动相关性的方法。以此研究了印度板块东、西触角强震对青藏块体地震活动的影响,结果表明阿萨姆地区的强震活动与青藏块体的强震活动具有很高的相关性,而帕米尔地区的强震影响较小。通过与R值评分及基于板块动力作用分析结果的比较,证实了本方法的有效性。Through the study on the relative regional seismic activities in Qinghai -Tibet plateau which were influenced by strong earthquakes occurred in the east and the west antenna of Indian plate, a quantitative method of relativity analysis for different regional seismic activities is introduced, and is used to solve the practical problems. The results show that two antennas take on different action. The strong earthquakes occurred in Assam region provoked the seismicity of Qinghai - Tibet plate, and that in Pamir region had less influence to Qinghai -Tebet plate. Compared R-value with the result based on plate dynamical mechanism, the validity of this method is confirmed.
