The coda attenuations below 10 seismic stations in the southern Tianshan region were studied in this paper by using the earthquake waveform data recorded through the Xinjiang Digital Seismic Network. 397 earthquakes with M_S ≥ 2.0 with the epicentral less than 60km around studied stations were used. The result showed that the average coda Q₀ value of the southern Tianshan region is about 190~390 among which Kashgar and Wuqia have the lowest value. The correlation coefficient of mean frequency η is about 0.62~1.00. The relationship between the scattering attenuation and the frequency in the southern Tianshan region can be expressed as Q=261.2±110.8f^0.80±0.28,suggesting that studied region is a tectonic active zone characterized with low Q₀ and high η values.
