摘　　要：在近年全国地震大形势研究的基础上,根据中国大陆地震活动的时空强演化图像及其相关参数的统计结果,并结合大陆周围附近地区强震活动对其内部的影响等客观现象,对大陆地震活动趋势进行了研究预测。结果认为,中国大陆第五地震活跃期到2001年已经结束,2008年3月21日新疆于田7.3级地震可能是中国大陆新的地震活跃期开始。Based on analyses of macro-situation of nationwide earthquakes in recent years, the continental seismicity trend of China has been analyzed in this paper according to the seismicity evolution patterns of time, space and strength in the mainland of China and the statistical results of related parameters, as well as combining the influence of strong earthquake activities around the mainland. The results suggest that the fifth seismic active period of the mainland has finished in the year of 2001, and the Ms7.3 earthquake occurred in Yu Tian, Sinkiang on March 21, 2008 may probably indicate the beginning of a new turn of active period of the mainland of China.
