中文摘要：
根据发生在云南地区震级大于3.0级的地震资料,采用最小二乘法对该地区的峰值加速度、加速度反应谱、峰值速度、峰值位移、均方根加速度等多个地震动参数进行回归分析。结果表明,该地区的地震动衰减关系的形态与前人的研究基本一致,但水平向差异较大;长周期部分的离散性较大,需进一步收集资料进行研究。
英文摘要：
Based on the M 〉 3.0 seismic observation datum collected in recent years in Yunnan, we 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 we obtained simulates with that of former resear ches, 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.
