In this paper,the method of calculating Q value with depth in the cr-ust by means of data of near earthquakes is described. It is found that the relationship Q (z)=26.27z-14.4(z>11Km) may be adopted in Beijing and its adjacent region.The results obtained also show that Q value is 300-400 in the depth from 11-15Km which is the average focal depth in Beijing area,and Q-1000 approaching to the bottom of the crust.
