【摘要】 根据重庆台网建设的时间阶段性,在对不同震级下限地震频度时间特征分析的基础上,研究了重庆地区不同时段的G-R关系和震级分布特征,并运用z检验方法对不同时段地震目录差异的显著性进行了分析,进而评估了重庆地区1970年以来不同时段的地震目录完整性,为区域地震活动性研究中地震目录的合理运用提供参考依据。更多还原

【Abstract】 According to the network construction time period of Chongqing,based on the analyses of the frequency character with the different magnitude threshold in Chongqing area,the author study the G-R relation and magnitude distribution characteristics in different periods,applying the Z Test Method to analyze the difference between the small earthquake catalogue in different periods,then we evaluate the catalogue completeness of small earthquakes in different periods since 1970.The result may provide reference for people to apply reasonably the earthquake catalogue to the regional seismicity research.更多还原
