| 英文摘要 | By using 560 Lg coda Q(0) values measured on propagating paths, the Q(0) image in the crust beneath the North China region is restructured with a stochastic modeling and the singular value decomposition. The result indicates that there is remarkable lateral heterogeneity on Lg coda Q(0) distribution in the crust beneath the North China region, similar to the velocity image, and closely related with the known surface geological features: the low Q(0) areas exist beneath the Taihang and Yanshan mountains and the Luxi uplift area, and high Q(0) values appear below the Jizhong, Huanghua and Jiyang depressions and the plain areas. There is a clear division between the high and low Q(0) values. Compared with the heat flow values in North China, most the low Q(0) value areas are located in the high heat flow areas. It is possibly related with hot material activity in the crust below these areas. Although there is a clear difference between the high and low Q(0) value areas in the crust of North China, as a whole the North China belongs in low Q(0) value abnormal region. It means that the region is a high seismic wave attenuation area. Probably it is resulted from the interaction between Eurasia and Pacific plates, which causes the crust thinning and hot material upwelling. |
