本文将逻辑函数方法用于我国西南强震年度危险性的判定,具体组建了一组预测我国西南川、滇、藏三省(区)7级及7级以上强震年度危险性的逻辑代数预报方程,该方程历史拟合率高,外推检验效果良好,表明逻辑函数方法是地震集成预报较有前途的方法之一。 In this paper, the logic function method is applied to the annual risk assessment of strong earthquakes in Southwest China, and a set of logic algebraic forecasting equations is established specifically for predicting the annual risk of earthquakes of magnitude 7 and above in the three provinces (regions) of southwest Sichuan, Yunnan and Tibet , The history of the equation fitting rate, the extrapolation test results are good, indicating that the logic function method is one of the more promising seismic integrated forecasting method.
