摘　　要：通过各类已发表的文献和历史资料,收集了1960～2009年期间发生在中国大陆地区ML≥2.9级的40次水库诱发地震,8分析了40次地震与坝高、库容、蓄水时间、最高水位时间、最大诱发地震强度和发生时间的统计关系,并得出了各个参数之间的统计结论,此结论可为中国大陆地区水库最大诱发地震强度和发生时间的预测以及后续发展趋势的判定提供参考依据。Through various published literature and histo rical data, we collected 40 reservoir- induced earthquakes more than ML2.9 occurred in China Continent from 1960 to 2009. This paper analyses the statistical relationship of dam height, capacity, storage time, time of the highest water level, the maximum induced earthquake intensity and the occurrence time of 40 reservoir-induced earthquake cases, and gets statistical conclusion between the various parameters. The results provide reference bases for predicting intensity and time of reservoir-induced earthquake and determining future development trend in China Continent.
