【摘要】 本文选取判别每年可能发生地震的最大震级范围的４个地震活动指标，对临汾盆地３１５年至１９９５年２月Ｍ＿ｓ≥４．７５的地震（余震除外）序列，应用模糊数学进行了处理，给出了判别３个震级范围，即５．５≤Ｍ＿ｓ＜６．０，６．０＜Ｍ＿ｓ≤６．５，Ｍ＿ｓ＞７．０的模糊关系方程。对此方程通过对３个典型类地震样本，以及未参加建模的２个地震样本进行了检验与预测。结果均与实际符合较好。本文还对１９９５年２月之后１年内临汾盆地可能发生的地震的最大震级范围进行了估计，结果为Ｍ＿ｓ＜５．５。更多还原

【Abstract】 Selecting 4 seismicity indexes that can discriminante maximum,magnitude range per annum, the paperhas processed a seismic sequence (Ms≥4. 75)from 315 to 1995 in Linfen basin using the fuzzy mathematics,has given 3 fuzzy relation functions that 3 ranges of the magnitude are 5.5≤Ms<6.0,6. 0<Ms≤6.5, andMs> 7. 0 respectively. The results of checkking and forecasting almost coincide with the practice. The maxi-mum magnitude range within an year after 1995 in Linfen basin has been forecasted, the result is Ms<5.5.更多还原
