Based on characteristics of the surrounding block faulting and block movement in Weihe extensional basin, the structural model of earthquake preparation is established to explore the mechanism and provide a scientific basis for the studies on earthquake preparation and distribution of the similar basin and earthquake disaster reduction as earthquake monitoring, prediction, and prevention.%依据拉伸型渭河盆地块体周边断裂活动特征和块体运动特征,建立了盆地地震孕育发生的构造模型,旨在探索地震孕育发生的机制,为研究类似盆地地震孕育、发生及其分布规律和地震监测预报、震灾防御等各项防震减灾工作部署提供科学依据.
