摘　　要：通过在百年时间域、45°×35°空间域对2001年昆仑山口西8.1级特大地震的孕震过程和中强地震活动图像演化进行时空扫描研究,认为该地震存在清晰的长期、中期、短期和临震几个孕育阶段,给出了各阶段清晰有序的地震活动图像,并找出划分各孕育阶段的标志性地震.同时指出8.1级特大地震的特殊性和预测预报的困难性.The pregnant process of west to Kunlun Mountain Pass earthquake with M8.1 in 2001 is researched in a hundred years and 45°×35° space,and the seismicity image evolution of moderate strong earthquakes is scaned in time and space. It is considered that in long,middle, short, and impending terms the different pregnant stages of the M8.1 earthquake are clear, the systematic seismicity images for every stage are given, and the symbolical earthquakes are found for each stage.Finally, the particularity of great earthquake with M8.1 and difficulty of earthquake prediction are showed.
