摘　　要：分析了中国台湾省自１９９０年以来Ｍｓ≥７．０的地震发生时刻前后的日月引潮力变化，研究了日月引潮力的变化率与这些地震的关系，结果表明，日月引潮力的变化率与这些地震的发生时有密切的关系，其对台湾省大地震的发生可能有一定的触发作用。In this paper, from discussing the variance ratio of each component of the tidal force and 21 major earthquakes (Ms≥7.0) occurred in land and offshore area of Taiwan province of China in 20th century the relationship between the variance ratio of the tidal force and earthquake is studied. The result indicates that occurrence times of these earthquakes have obvious correlation with the variance ratio of the lunisolar tidal force and the lunisolar tidal force plays an important role in triggering earthquakes possibly.
