This paper selected Wuqia area as the research region where is the seismically active region of strong earthquakes in Xinjiang region. Through time-space zone analysis, five different methods such as synthetic lack information quantity, synthetic information entropy, information entropy, capacity dimension and information dimension were used to trace and study the three strong earthquakes occurred in Wuqia area from 1980 to 1988. Results show that either from the viewpoint of entropy (uniform degree) or from...

This paper selected Wuqia area as the research region where is the seismically active region of strong earthquakes in Xinjiang region. Through time-space zone analysis, five different methods such as synthetic lack information quantity, synthetic information entropy, information entropy, capacity dimension and information dimension were used to trace and study the three strong earthquakes occurred in Wuqia area from 1980 to 1988. Results show that either from the viewpoint of entropy (uniform degree) or from the viewpoint of fractional dimension number (ordered degree), the entropy decreasing (dimension drop) process is clear before strong events. Studies show that such entropy decreasing (dimension drop) process is probubly a characteristic physical quantity of the focal body of strong-shocks which is in the critical rupture. Therefore, it can be regarded as a method for strong earthquake prediction and dynamic monitoring of major risk regions.

本文选取新疆境内强震的高发区——乌恰地区作为研究区域,分别采用合成缺信量、合成信息熵、信息熵、容量维和信息维等五种不同的方法,通过时间域和空间域分析对乌恰地区1980—1988年发生的三次强震进行了动态追踪的研究。结果表明,无论是从熵的观点(均匀程度),还是从分维数的观点(有序程度)出发,强震前的减熵(降维)过程是明显的,研究表明,这种强震前的减熵(降维)过程可能成为强震震源体处于临界破裂的一种特征物理量,因而可作为强震预测以及重点危险区动态监测的一种方法。

This paper regarded the seismogenic process of earthquakes as a complicate system. With development of seismogenic process, the system was developed from the equibrium state towards the direction far from the equibrium state, its instability increases and approaches to the destabilized state. In this period, a number of precursors occurred and developed, the complexity increased. The paper used the information integration method in the systematic science to analyze the precursory. anomalies and determined, the...

This paper regarded the seismogenic process of earthquakes as a complicate system. With development of seismogenic process, the system was developed from the equibrium state towards the direction far from the equibrium state, its instability increases and approaches to the destabilized state. In this period, a number of precursors occurred and developed, the complexity increased. The paper used the information integration method in the systematic science to analyze the precursory. anomalies and determined, the comprehensive criteria for the anomalies. The probability synthesis of the united system parameters, information entropy and the ordereddegree are used as the transitional mark from steady state to non-steady state. The results show that the anomalies analyzed by using the information synthesis integration method could reflect that the seismogenic process had developed "into the short-term stage. Therefore, this method provides a reliable basis for the short-term earthquake prediction and it is of "practical significance.

本文将地震的孕震过程视为一个复杂系统,随着孕震过程的发展,系统从平衡态向着远离平衡态方向发展,不稳定性增大,并向着失稳态接近,这时大量前兆发生发展,复杂性增加。文中应用系统科学中的信息集成方法分析前兆异常,确定异常综合判据,用统一的系统参量概率合成、信息熵、有序度等作为系统由稳态向非稳态过渡的标志。结果表明,用信息综合集成方法分析后的异常反映了孕震过程演变到短期阶段。该方法为短期地震预报提供了较为可靠的依据,具有实用化意义。

Based on probabilistic preprocessing,The observation values for the observed items of subsurface fluid in the joint area of Hebei,Shandong and Henan province have been transformed into probability and time sequence.The synthetic information entropy of the information source system formed by subsurface fluid in the area is calculated.The relation between the variation of the synthetic information entropy and Heze M s5.9 earthquake (1983) and Renxian Ms5.0 earthquake (Hebei province,1985)is analyzed.The results...

Based on probabilistic preprocessing,The observation values for the observed items of subsurface fluid in the joint area of Hebei,Shandong and Henan province have been transformed into probability and time sequence.The synthetic information entropy of the information source system formed by subsurface fluid in the area is calculated.The relation between the variation of the synthetic information entropy and Heze M s5.9 earthquake (1983) and Renxian Ms5.0 earthquake (Hebei province,1985)is analyzed.The results show:there are two times obvious entropy decreasing before the two events and the later is more distinct than the former.The two events both occurred at the low entropy moment.The entropy recovered after the shocks.This process reflects maybe the ordinal change of the entropy decreasing in the course of earthquake development and occurrence for a subsurface fluid information system.Study shows 0.45 is the precursory anomalies' alarm line for an earthquake in the area,and the closer to an earthquake,the larger the entropy decreasing,the greater the magnitude of the earthquake.

采用概率化预处理方法 ,把冀鲁豫交界区地下流体多种观测项目的观测值转化为概率值时间序列 ,在此基础上计算了该区地下流体构成的信息源系统的合成信息熵值 ,分析了合成信息熵值变化与 1 983年菏泽 Ms5.9级地震和 1 985年河北任县 Ms5.0级地震的关系 ,结果显示 ,在这两次中强地震前分别有两次明显的减熵异常过程 ,并且一次比一次减熵过程更明显 ,中强地震都发生在低熵值处 ,震后恢复到高熵值。这可能反映了地下流体构成的信息源系统在地震孕育和发生过程中的减熵有序变化。通过研究认为该区减熵到 0 .45为发震前兆异常警戒线 ,并且离中强地震发生的时间越近 ,减熵过程越大 ;震级越大 ,减熵过程越明显
