摘　　要：本文研究了渭河断陷盆地及邻近地区介质品质因子的分布特征,探讨了其与该区域速度场、地质构造和地震灾害分布之间的关系。结果表明该区域介质品质因子分布与速度场之间存在着较好的对应关系,并与该区域的地震灾害分布密切相关。In this paper, the characteristic of Q value distribution beneath Weihe fault depression and its adjacent area is studied The relationship between the characteristic of Q value distribution, seismic velocity, geological structures and earthquake disaster distribution in this area is discussed The results show that the distribution of Q value is consistent with the image of P wave velocity distribution in the studied area and is closely related to earthquake disaster distribution in this region
