摘　　要：对华东地区（２９°～３５ ．５°Ｎ，１１５°～１２５°Ｅ）１９７０ 年以来１４ 次ＭＳ≥５．０ 和５ 次ＭＳ≥４．６ 地震的诱发前震特征进行了研究。初步研究结果表明，诱发前震在华东地区具有较好的预报效能，可以作为本区中期预报尤其是发震地点预报的判据之一。同时对本区诱发前震预报参数进行多种优化组合，给出了适合本区的诱发前震预报参数，并对未来中强震进行了尝试性预报。The induced foreshock characteristics of 14 M S≥5.5 and 5 M S≥4.6 earthquakes of east Chinese area(29°～35.5°N, 115°～125°E) since 1970 have been studied. It is preliminarily concluded that the induced foreshocks of east Chinese area have a better prediction effecience, which is applied to the medium term prediction for earthquake, especilly for epicentre location. The prediction parameters of induced foreshock in the area are optimistically combined. The adequate parameters of induced foreshock for the area are given, and the moderate earthquake in future is predicted.
