| 英文摘要 | By using Lg coda time series with higher signal-to-noise ratio from North China telemetry and digital seismic network during the period from 1989 to 1998 ( M-L greater than or equal to 3. 0), the spatial distribution of Lg coda Q ( Q = Q(o) f(eta)) is obtained with the stacked spectral ratio method through pretreatments of filtering and eliminating background noise. The results show that there is a significant lateral heterogeneity on Lg coda Q distribution in North China, which is approximately consistent with the velocity distribution in the crust of the region, and is related with the surface geological features. There are higher Q(o) values on propagating paths located in up-welling areas, and lower Q(o) values in depression areas. There are eclectic Q values on propagating paths located in both upwelling and depression areas. On one hand the crustal structure in North China region there is no great step change so as to destroy seismic wave-guide. On the other hand Lg coda Q(o) value reflects basically intrinsic attenuation of the crustal medium anelasticity. |
