选取1970年以来中国大陆东南地区5.0级以上、华北地区5.5级以上、西部地区7.0级以上地震作为研究对象, 并选择了8种物理意义明确、独立性较强的地震学指标进行全时空的异常扫描, 通过改变采样时间域尺度、空间域滑移及强度区间等样本条件, 分析对地震学指标时间进程计算结果的影响, 并讨论了空间扫描滑移方向相对于区域主应力方向的变化对参数扫描结果的影响. 结果表明, 空间参数的改变对扫描结果的影响最大, 并给出了不同震级地震学指标在扫描中影响最小的空间范围和时空扫描的最佳条件参数.

Taking earthquakes above M_S5.0 in southeast China, above M_5.5 in north China and above M_S7.0 in the west of in mainland China since 1970 as research object, this paper selects 8 kinds of seismological indexes with clear physical meaning and strong independence for whole time-space abnormal scanning. By changing sampling conditions of time scale, spatial slip and strength interval, we analysed the influence on seismological index time course calculation results, and disscused the influence of spatial scanning slip direction compared with changes of regional main stress direction on the calculation results, the results show that change of spatial parameters had the most influential effect for scaning results, and the minimum influential spatial scope and the optimum condition parameter of time-space scanning are given for scanning different magnitude seismology indexes.
