地震危险性灰色关联度分析

ANALYSIS OF CORRELATIVITY OF SEISMIC RISK

将地震现象视为一内部信息部分已知、部分未知的灰色系统，表征强震发生前地震危险性的指标值实际上是灰数。据此应用灰色关联度分析的方法对我国的昭通、松潘、兰州、苏鲁交界处和长江口地区进行了多因素的地震危险性评价和预测，并将其结果与模糊数学方法所得的结论进行了对比。

Earthquake phemomen as grey system is treated in which information is known partly and unknown partly. Actually, the index of seismic risk prior to strong earthquake is a grey number. The assessment and prediction of seismic risk by myltifactor is conducted using analysis method of grey correlativity for Zaotong, Songpai, Lanzhou, conjecture area of Jiangsu and Shandong and Yangtze river mouth. The results obtained with those of using fizzy mathmetics method are compared.
