The improved Empirical Green＇s Function method considers the displacement heterogeneity at each sub- faults of fault of main shock, makes the physical meaning of Empirical G~een＇s Function method clearly, and a- bandons previous empirical method which confirms small earthquake numbers used to synthesize main shock. We use Wenchuan Ms6. 4 aftershock records as the Empirical Green＇s function, and simulate the acceleration time histories at Baihe Station in Jiuzhai County, Anhong Station in Songpan Country, Gaolan Station and Zhonghe Station in Chengdu by the improved Empirical Green＇s function method. Compared with former results by Empir- ical Green＇s function method, response spectrums in the simulation results are more closer to the records, which prove the complicated distributions of epicenter displacements can be reflected by the improved Empirical Green＇s function method, this method can be used to estimate site ground motion processes in engineering seismology.
