Abstract: We have done statistical analysis for descending amplitude of crustal movement in Quaiernary period (DACMQ).Those indicators,such as mean H,standard deviation σ,asymmetry As and kurtosis Ku on DACMQ,denote various character of seismic dynamics in subdistricts.The author considers that this method can be used as a powerful quantitative indicator for evaluating degree of seismic risk and researching dynamics of the earth.

Key words: Crustal movement, Statistical analysis, Seismic risk evaluation

摘要: 通过第四纪地壳运动降幅统计指标,即均化值H、标准差σ、非对称As及峰态Ku,揭示工作区各亚区不同的地震动力学特征,从而为地震危险性评估与地球动力学研究提供一种定量的地质标志。
