摘要
在以前工作的基础上,对模糊聚类分析方法的实用性作了进一步研究。参照中强地震前地震异常的时间、强度及空间变化等特征和研究结果,重新提取了描述地震前兆异常的十项指标。结果表明,用模糊聚类分析方法合理地提取地震前兆异常特征,可以作为新疆地震趋势预测的有益信息,并可获取更好的预测效果。
Based on the former work done by the auther, the practicality of fuzzy cluster analysis method has been further studied. With reference to the change of anomaly time, intensity, space, and other characteristics before medium and strong earthquakes, ten indexes used to describe precursor anomaly of earthquakes are re-extracted. The result shows: through reasonably extracting characteristics of seismic precursor anomaly and using fuzzy cluster analysis method, useful information can be provided for seismic tendency prediction of Xinjiang and better effect can be obtained.
