摘要
多层递阶预报是动态系统的新型统计预报理论。由于它把动态系统看成是一个时变参数系统， 因而与客观实际较为符合， 预报误差也相对较小， 利用它来预报一个地区未来的地震活动趋势， 具有一定的实用价值。
The multilayer recurrence forecast is a new statistical forecast theory of dynamic system. Because the dynamic system is taken as a time varying parameter system, it relatively conforms the present condition and its forecast error is smaller than the usual. So, it may be of a certain practical value for seismicity tendency forecast of some region in the future.
