中国大陆地震构造带的初步划分及其应用

A Tentative Differentiation and Application of the Seismotectonic Belts in China Mainland

本文依据深部地球物理场、区域大地构造、地表活动断裂、地震活动等，划分了中国大陆的地震构造带，同时分析了地震构造带的活动特征和孕震构造条件。在此基础上，具体地把地震构造带的概念应用于地震危险区分析之中，探讨了地震危险区及地震前兆异常与地震构造带的关系。本文提出以地震构造带研究作为地震监测和预报工作的基础，将地震构造带作为系统性的活动构造条件应用于地震危险区划分之中。

Based on manifold materials of geophysical fetid, regional tectonics, surface activefaults, seismic activities and so on, we differentiated the seismotectonic belts (SB) in Chinamainland, and meanwhile, analyzed their active features and seismogenic tectonic conditions. Moreover, the seismotectonic belts were applied in seismic risk region (SRR) analysis to discuss the relationship among SB, SRR and precursory anomaly. It has been suggested that the seismotectonic belt study can be a basis of earthquake forcasting practice.The study will have a great meaning for both the theory and practice of earthquake prediction.
