摘　　要：通过对我国地震台网观测资料以及地震活动特征的分析 ,给出了处理中小地震活动性图象的网格点密集值计算方法 .该方法综合考虑一定时空及震级范围内地震的数量和震中分布这两方面因素 ,并特别强调了计算参量的选取应充分考虑资料精度的影响 .应用该方法得到的地震活动性图象能够准确、合理地反映地震活动特征并具有较好的稳定性 .经该方法处理的图象是对地震活动性进行定量分析的基础 ,在地震趋势分析。Analysis of seismic data and seismicity characteristics in China, we gave a method to deal with seismic patterns by calculating density at grid nodes. Number of earthquakes and epicenter distribution are considered synthetically in this method. Effect of datum accuracy is stressed on parameter confirmation. Seismic patterns from this method are stable and can reflect seismic characteristics reliably. These seismic patterns are the base of quantitative analysis of seismicity. It can be applied in seismic tendency analysis and medium long term earthquake prediction, earthquake countermeasure and risk mitigation.
