| 摘 要： | 本文针对目前地震危险区边界划分上存在的问题,从地震地质和地震构造的角度,结合测震学方法进行了分析,指出地震分布和地震危险区边界划定与活动构造有密切的联系。依据这一思想,阐明了构造活动与地震活动的关系,初步提出了地震危险区边界判析的原则,即把地震危险区限制在一定的地震构造区(带);其边界依据活动构造划定;在地震危险区内部进行发震构造条件研究,并对这些发震构造(活断层)进行活动度分析;分层次地对地震危险区范围及其危险度进行确定。 本文着重进行了活动构造的研究,对中国大陆的活断层、新生代盆地、地形面以及古地震等作了活动时代、活动性质、活动强度等多方面的论述。

| Abstract: | From the viewpoints pf seismogeology and seismotectonics, and based 0n the analysis by using the seismometry method, this paper clarified that the earthquake distribution and boundary delimitation of seismic risk areas would be closely related to the active tectonics. Besides, the principle for delimitating the boundary of seismic risk areas was proposed, and some evidence of active tectonics for delimitating the boundary was also described in the paper. Finally, the seismic risk areas for 1993 were delimitated according to the above-mentioned researches. |
