摘要
对中国地震局原分析预报中心测震学科1988～1999年度划定的南北地震带强震（M≥7）危险区进行了回顾和分析。结果表明，从过程角度研究前兆地震活动图像及其演变是年度和中短期强震预测的有效途径，这为南北地震带强震震情跟踪提供了条件。
The article evaluates the annual strong earthquake risk regions identified by authors from 1988 to 1999 along North-South Seismic Zone. The results show that it is an available approach to apply seismicity precursors and their evolution to annual forecast of strong earthquakes. It provides a basic condition for tracing short-term precursors of strong earthquakes.
