Using the 2006 and 2010 yushu  two earthquake sequence digital wave data recorded by yushu station, based on single scatter model by Sato，the Q value in yushu region is calculated, and relationship between the Q value and frequency is polyfited. generally, the Q value and the seismotectonic activity showed some correlation, the former average of  Q₀  value higher than the latter  average of Q₀ value.
