【摘要】 进入21世纪以来，全球大地震频发，为了探讨天文因素对地震的影响，本文采用相关性的统计分析方法,比较系统地分析了太阳活动、地球自转、月亮赤纬角与天体引潮力等天文因素对21世纪初全球M≥8.0地震的影响，对于太阳活动，本文重点分析了太阳活动的11年周期和世纪周期。分析结果表明，对于地球自转，无论是本文的分析，还是前人的研究，其因果关系尚不明显；而对于太阳活动，太阳活动世纪周期的谷值期可能是导致21世纪初全球大地震频发的重要天文因素。值得进一步深入研究。更多还原

【Abstract】 Since the beginning of the 21^st century, major earthquakes have frequently occurred worldwide. To explore the impact of astronomical factors on earthquakes, in this study, the statistical analysis method of correlation is used to systematically analyze the effects of astronomical factors, such as solar activity, Earth’s rotation, lunar declination angle, celestial tidal force, and other phenomena on M ≥ 8 global earthquakes at the beginning of the 21st century. With regard to solar activity, this study focuses on the analysis of the 11-year and century cycles of solar activity. The causal relationship of the Earth’s rotation is not obvious in this work and previous works; in contrast, the valley period of the solar activity century cycle may be an important astronomical factor leading to the frequent occurrence of global earthquakes at the beginning of the 21^stcentury. This topic warrants further study.更多还原
