| 摘 要： | 本文采用信息熵方法,视地震系统为开放系统,将震源区内的各种地震前兆作为信源,求取地震孕震过程的熵值变化。通过对“滇西九○年地震短临预报指标评选及方案“中优选出的１１项前兆指标的信息熵分析,表明在中强震前明显出现监视区地震短临预报的一种综合方法。

| Abstract: | Adopting infotmation entropy method, taking seismic system as open one, consideting vatious seismic precutsors within focal area as information source, changes of entropy in seismogenic procedure have been acquired in this paper. Information entropy analysis selected 11 ptecursory indicators from "Selection and Plan for Short-impending prediction in 1990 in Western Yunnan" shows that there obviously exists a entropy-decteasing procedure, further, a quantitative index is gained. This method is worthy of comprehensive one for earthquake prediction in the intensified monitoring area of Western Yunnan. |
