摘　　要：简要归纳了M7.9地震前地倾斜记录的异常及其特征,认为M7.9地震前地倾斜存在明显的阶段性异常,趋势异常持续3年以上,中短期异常由近场向600km范围扩展,700—850km范围的多个台站记录到较明显的临震异常,富蕴台地倾斜的掉格图像是M7.9地震最突出的前兆异常。The anomalies and characteristics of ground tilt before M7. 9 earthquake were summarized, We found the ground tilt had phasic anomalies before M7.9 earthquake, the duration of tendency anomalies was larger than 3 years, the medium--short period anomalies expanded from near region to the range of 600km, the immediate anomalies were recorded by some stations which far from the earthquake 700--850 km, the markedness precursory anomalies of MT. 9 earthquake was ground tilt drop map recorded by Fuyun station.
