Abstract By use of single scattering model(Sato),the varying characteristics of Qc value of JiujiangRuichang seismic sequence is studied from the digital earthquake record of Jiujiang station. The relation between the frequency and
Qc value is Qc(f)=（19.63±4.81）f 1.183 8±0.094 5. Before the 2005-12-03 ML3.9 earthquake, the Qc value changed obviously, the mean Qc value was higher, the aftershocks was more active；after this earthquake, the Qc value changed stably, the mean Qc value was lower, the aftershocks was not active. This feature is presumed that the JiujiangRuichang earthquake sequence would come into the quiet state.
Key words ：
Sato model
Q-c value
Jiujiang-Ruichang region
seismic activity
earthquake sequence
