摘要
依据青海高原1900年以来Ms≥4.7的器测地震记录,以历史地震资料为基础统计各个震级档在1900-2008年内发生频次和各年地震发生最大震级。最后,根据统计资料建立震级-频次关系方程式,利用统计分析软件SPSS对其进行拟合分析。根据震级与频次拟合分析得到lgN=5.317-0.614m拟合方程,通过对震级与频次关系式进行检验,震级与频次之间的密切程度高。并对该方程进行验证,震级与频次关系方程高度显著,该拟合方程比较合理。所以,震级-频次关系式lgN=a-bm适合于青海高原历史地震震级与频次的分析。
Based on instrumental records of historical seismic data during the year 1900-2008,the largest earthquake magnitude and frequency based on various statistics magnitude stall on the frequency of occurrence（the earthquake（Ms≥4.7）.According statistics to establish the magnitude-frequency relationship equation,and use the statistic software of SPSS to fit their analysis.to establish the regression lgN = a-bm by the analysis of the result of magnitude and frequency analyze.The relationship between magnitude and frequency is high degreed in correlation and validation is highly significant reasonable by the test of practice.Therefore,the lgN = 5.317-0.614m of magnitude-frequency relation is suit to analyze the magnitude and frequency of historical earthquakes have taken place in Qinghai Plateau.
