| 摘 要： | 针对过去应变积累释放曲线或模型存在的不足，根据G-R关系以及能量震级经验关系， 推导出一个相对独立的应变积累速率公式. 同时在活动地块假说基础上，选取了中国大陆地震活动较为典型的几个地块分区，在考虑历史地震目录完整性基础上，利用1970年以来的小震资料，计算了各地区6级以上地震的年均应变积累速率，从而给出各地震分区相对的地震活动水平；并将之用于改进后的模型，通过对各地震分区现今所处应变状态以及目前状态在其地震轮回活动中所处阶段的研究，探讨了各地震分区的未来地震形势.

| Abstract: | According to the deficiency of the strain accumulating and releasing curves and the previous models, the strain-accumulating rate of the strain accumulating and releasing model has been deduced based on the G-R relation and the empirical formula between energy release and earthquake magnitude, where the strain-accumulating rate is relative independent of the strain-releasing rate. 5 typical areas in Chinese mainland are selected on the basis of the hypothesis on active tectonic block, and small earthquakes from 1970 are imported to calculate the annual strain-accumulating rates considering the completeness of historical seismic data. Having introduced the strain-accumulating rates into the amended model, present strain phases are got. According to the present stages in their own cycles, the future earthquake tendency of each sub-region is discussed. |
