根据宁夏数字地震台网19 个地震台的294条波形资料,研究了宁夏南区及北区的衰减模型和各台站的场地响应。采用三段几何衰减模型拟合，得到宁夏南区和北区非弹性衰减Q 值随频率f 的关系分别为：  和 ； 19 个台站的场地响应除泾源台外其余台站没有显示出明显的放大效应,这和实际情况基本相符。

 Based on 294 digital seismograms recorded on 19 stations of  Ningxia Telemeterd Network, the attenuation of ground motion and site response of each station is investigated in the South and North Ningxia region. Assuming a trilinear geometrical spreading model, we obtained the attenuation function in South and North Ningxia region:  and . The site response of 19 stations do not show significant amplifications expect Jingyuan station,Which is basicly consistent with Actual situation.
