较详尽地阐述了地下水位动态主要影响因素的类型和特征。根据地下水位多年动态特征和影响因素对地下水位的不同动态,提出了地下水位物理参量中短期(一年尺度)地震预报的三种异常标志、中短期异常的计算机提取方法优化所遵循的原则。在实用化攻关、“八五”攻关的基础上,对地震预报的中短期异常识别方法进行了分析、对比、优化。最后对优化后的五种中短期异常提取方法进行了简要介绍。
The types and characteristics of the main influencing factors of groundwater level are expounded in detail. According to different dynamics of groundwater table and its influencing factors to different groundwater levels, three abnormal signs of short-term (one-year) earth-quake prediction of groundwater table are proposed. The principle of computer aided optimization of short- and medium-term anomalies is proposed. On the basis of practical research and “the Eighth Five-year Plan”, the methods of short-term anomaly identification in earthquake prediction are analyzed, compared and optimized. Finally, the optimized five short-term anomaly extraction methods are briefly introduced.
