Abstract：268 pieces of digital oscillograms of 32 seismic events of form ML2.6 to ML4.9 recorded at 20 seismologic stations located on Ningxia region and its adjacent areas occurred from May, 2009 to Oct., 2010 were studied and the relation of inelastic attenuation %Q value with media frequency in the crust of this area, the site responses of 20 stations were calculated with the genetic algorithm. The results indicate that the frequencydependent relation of inelastic attenuation value Q in the studied area is estimated as: Q(f)=337.67f 0.455 4. The Q value is close to the regional result in Shanxi and Zhejiang. It probably indicate that the geological tectonic activity is in a normal level.
