模糊数学方法在地震预测中的应用研究及其实效

20世纪80年代以来,针对地震孕育期间孕震信息的模糊性,国内开展了多项模糊数学方法在地震预测中的应用研究。应用这些方法可以将多项指标所显示的孕震的模糊信息转化为清晰的地震预测结果。现仅介绍模糊聚类分析和模糊综合评判两种常用方法在地震预测中的应用研究概况及其预测实效。

Application Research and Actual Effect of Fuzzy Mathematic Method in Earthquake Prediction

Since 1980s, the application research of some fuzzy mathematic methods on the earthquake prediction have been developed in accordance to the fuzzy characteristic of the information during preparing earthquake. Using the fuzzy mathematic method, the fuzzy information of earthquake preparation shown by the seismicity multifold indexes was transformed into the clear results of earthquake prediction. A general idea of the research of two methods of fuzzy mathematics, fuzzy clustering analysis and fuzzy synthetic evaluation, applying in the earthquake prediction and actual effects are briefly introduced.
