| 摘 要： | 为合理估计汶川8.0级特大地震后中国大陆的地震形势,本文通过对中国大陆特大地震后地震活动的统计分析,初步获得了对中国大陆特大地震调整作用的一些认识:①特大地震发生后1年内,除余震区外,中国大陆其他地区的地震活动以应力调整为主线,发生7级以上地震的可能性较小;②调整作用主要发生在西部的青藏活动地块区;③青藏地块区特大地震对华北地块区的地震调整作用较小.

| Abstract: | For a reasonable evaluation of earthquake tendency after Wenchuan M_s8.0 earthquake in Chinese mainland, a preliminary study of seismic activity after great earthquakes in Chinese mainland is presented, which shows: (1) in 1 year after a great earthquake, outside of the aftershock area, the seismic activity in Chinese mainland is controlled mainly by the adjustment of stress from the great earthquake, and the possibility of a strong earthquake ( M ≥7.0) is low; (2) the adjusting effect of the great earthquake occurs mainly in Qinghai-Xizang active block of Western China; (3) on Northern China active blocks, the adjusting effect from great earthquakes of Qinghai-Xizang active blocks is less. |
