摘要

Based on the M>3.0 seismic observation datum collected in recent years in Yunnan Province, the authors make regression analysis for multiple seismic motion parameters such as peak ground acceleration, response spectrums of acceleration peak, ground velocity, peak ground displacement and rootmeansquare acceleration by least square method. The result shows that the seismic attenuation relation curve obtained simulates with that of former researches, but there is great difference between them in horizontal direction. The standard deviation in long period is relatively large, which means more data should be collected in the future research.
