摘要: 按照中国大陆及邻近地区活动地块和地震带的划分方案, 使用Mapsis软件选取了汾渭地震带1000年以来MS4.7以上地震, 这样的地震资料应具有地质单元的统一性。 使用数学中19阶多项式模型, 对地震资料进行最佳逼近拟合, 并递推未来1—2年时间尺度预测。 模型中的参数用最小二乘法求取。 引用一种数学方法来描述汾渭地震带的地震趋势规律。

Abstract: According to the structure division result of active block and seismic zone, we select the MS≥4.7 earthquakes the Fenwei seismic zone using MAPSIS software. This data may have the characteristic of one geology unit. Using the 19-order non-linear mathmatical polynomial whose correlation coefficients can be obtained by the method of least squares, we made optimum approaches to data by fitting, and made a prediction of seismic tendency in 1 to 2 years' time. This provides a mathematical model prediction method to describe the rule of seismic tendency in the Fenwei seismic zone.
