摘　　要：本文通过对我国东部四个诱震水库的地质调查及其资料分析,探讨了水库地震诱发过程中所涉及的诸环境因素。研究表明:水库地震的诱发因素很多,但大体上可归纳成库水渗透条件和发震构造条件两类;这些环境因素只有在它们按一定方式恰当地组合成一个统一体存在于同一库区(段),水库地震才有可能诱发产生。因此,预测水库地震一个很重要的工作就是要查明库区诱发地震的环境因素及其总体组合条件。Through geological investigation for four reservoirs of induced earthquake in eastern China, we have researched for various environment factors dealed with in the process of induced reservoir earthquake. This research indicates. the environment factors of reservoir earthquake can be divided roughly into permeating condition of reservoir water and statutory, when these factors exit and combine properly in the same reservoir area as a united system, reservoir induced earthquake will possible occur. Therefore, a very important basis of predicting reservoir earthquake is to find out integral environment conditions of induced earthquake in reservoir area.
