摘　　要：本文研究总结了贵州水库地震的成因类型、诱发因素和特点。贵州的水库地震主要是断层型,其次是混合型和气爆型,滑塌型相对较少。库容、水库水位、库区岩石类型和岩层结构、库区断裂构造是影响和控制水库诱发地震的主要因素。贵州发生明显水库地震的水库的基岩以碳酸盐岩为主,大型以上水库才会诱发地震,水库地震的发生受水库水位影响明显,水库地震的强度受构造背景影响,水库地震震级相对较小、影响范围小,水库地震容易造成"小震大灾"。In the paper,the induction factors,genetic types and characteristics of reservoir induced by earthquakes in Guizhou are studied. Fault type is most,followed by mixed type and gas explosion type,landslide collapse type is least in reservoirs induced by earthquakes in Guizhou. Water capacity,water level,rock types,strata structure and fault structure of the reservoir are main factors which influence and control reservoir induced earthquakes in Guizhou. Carbonate area,large- scale and high water level reservoirs are the dominant factors of reservoir induced by earthquakes. However,tectonic background affects the inducing intensity of reservoir in earthquake. It was easily caused that small earthquakes results in large casualty and property loss by Reservoir induced by earthquakes.
