摘　　要：2008年5月12日四川汶川发生MS8.0地震,甘肃省甘东南地区也成为地震的受灾区。"十五"期间在甘东南地区共架设了20个固定强震台站,大多数台站都记录到了这次地震,其中最大加速度峰值为184.9 cm/s2。本文展示了全省20个台站所记录的共60道强震记录信息,并初步分析了加速度的衰减规律。The great earthquake occurred in Wenchuan, Sichuan province, on May 12,2008, and the southeastern part of Gansu province was also the disaster area. During the 10^th 5-years plan period, 20 strong motion stations were erected in southeastern part of Gansu, and most of them recorded the earthquake, in which the maximum acceleration value is 184.9 cm/s^2. In the paper, total 60 records of strong motions from 20 stations in Gansu are showed and the attenuation of acceleration in Gansu is preliminariely analyzed as well.
