基　　金：Fund for the research was granted from Institute of Crustal Dynamics,China Earthquake Administration(No.ZDJ2013-05)and(No.ZDJ2010-20) 摘　　要：Taking the northeast seismic zone as an example and based on the magnitude-frequency distribution principles of the G-R relationship and the study on the temporal and spatial distribution characteristics of the minimum magnitude of completeness M C in each time interval,this paper makes a statistical analysis on the seismicity parameters of the research area and explores the influence of the completeness of small earthquake data on the seismicity parameters and seismic hazard analysis.It shows that the completeness analysis of the regional small earthquakes data provides a possible means for obtaining more accurate seismicity parameters that can better represent the actual regional seismicity level for areas of low seismicity.The research methods of this article and its conclusion can be used as a reference for the completeness analysis of earthquake data and seismic activity research. 关键词：地震活动性参数完整性分析地震数据地震带东北地震危险性分析时空分布特征地震活动水平
