摘要
中国大陆８级巨震群体活动的盛衰起伏，紧随全球整体活动的变化而变，并明显地受到太阳活动长期变化的调制。就个体巨震孕育而言，其供能机制可造成周围数千公里构造应力场持续多年的剧烈增强。因此，对于震级为８级的巨大地震的预测问题，必须在极为广阔的研究视野中探讨。
As for colonial activities of great earthquakes (M≥8) in continent of China,it has been found that the activities change along with e of global general seismicity,and the activities are obviously modulated by long-term variation of solar activity. As for the development of individual great earthquake,its energy-suppling mechanism may involve great increase of tectonic stress accumulated for many years in surrounding tectonic stress field of several thousands kilometers. Therefore it is pointed out that we should discuss prediction problems of great earthquakes (M≥8)with extremly wide view.
