| 摘 要： | 在较大地震的孕育过程中，随着弹性应变能的不断积累，孕震区有可能从原来的无序状态转变为一种在时间、空间上的有序状态，与之相联系的各种信息量的有序程度都有可能增加。本文引入信息熵来描述信息量的有序程度，结果表明，在研究范围内的多数地震前出现了熵减的过程，说明地震前确实存在一个从无序状态向有序状态转化的现象。文中利用信息熵方法，对福建省4个水氡观测资料进行分析，认为该方法，对各台的映震效能不同，虽然都通过了R值检验，但由于漏报率、虚报率的差异，从而影响了各台的R值评分；另外，用该方法提取的异常所反映出来的特征也不相同，如各台的异常持续时间和异常幅度同闽台地震的关系存在差异。 |

| Abstract: | Accompanying the gestation of some large earthquakes, the elastic strain energy accumulates and the state of seismogenic zone possibly turns to be regular from out-of-order either in time or in space. So, the interrelated information will be more regular. In this paper, the entropy of information is introduced to describe the extent of the order of the interrelated information. The results indicate that the entropies of the most of the earthquakes reduce in the research area. That is to say, the state of seismogenic zone does turn to be regular from the state of out-of-order. For addition, the entropies of information of different stations reflect different characteristic. We can have this conclusion through 4 different processes of water radon data in Fujian Province. |
