摘　　要：通过对过去近半个世纪水库诱发地震资料的分析,认为水库诱发地震的诱发因素尽管复杂,但一些国内外水库诱发震例表明,水库诱发地震的断层响应现象是明显的,这种现象由水库诱发地震的非均匀分布性、集中呈带性、地震带与水库位置关系的非确定性、地震带沿库区某些断层展布等方面所反映。Reservoir-induced seismicity （RIS for short） is the result from reservoir impounding. According to the research during past half century, the cause of RIS may be complex. However, based on the tectonic analysis of some RIS samples in the world and China, there existed obvious faulting response to RIS, which were shown as the heterogeneous distribution of the RIS epicenters, the RIS epicenters centralizing in a belt, the uncertain position relationship between the reservoir and RIS belt, and RIS belt being controlled by some faults in the reservoir area.
