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.
