摘　　要：分析了1954—2019年6个完整太阳活动周内云南省及周边M_(S)5.0及以上中强震与太阳活动的关系,结果显示,太阳黑子活动对地震活动有一定影响,49.6%的地震集中在太阳活动下降年(尤其是双周期下降年),发生在双周期的地震占全部震例的63.0%,在极小年及极小年附近,年均发震频次高于其他阶段。In this paper,the relationship between solar activity and M≥5.0 earthquakes in Yunnan Province and its surrounding areas during six complete solar cycles from 1954 to 2019 is analyzed.The results show that sunspot activity has a certain influence on seismic activity,and 49.6%of earthquakes are concentrated in the declining years of the solar cycle,especially in the declining years of double solar cycle.The earthquakes occurring inthe double solar cycle account for 63.0%of all earthquakes.The annual average earthquake frequency in and aroundthe solar minimum years is higher than that in other stages.
