| 摘 要： | 自２０世纪８０年代以来，在我国地震地下水动态观测网中陆续发现井水位在超远距离强震前的异常现象。这种异常表现为井水位的振荡与阶变，多出现在震前几小时至几天内，有一定的重现性。对这种异常的形成机制有多种不同观点，其中具有代表性的有强震的前驱波作用观点与强震孕育的林构造牵动观点等。

| Abstract: | Since the 1980's, the abnormal phenomena of well water level before super-distant strong earthquakes have been found in succession in the seismic groundwater behavior observing networks of china. The ocillation and step change of well water level are the expressions of such anomalies, that usually occur several hours or days before earthquakes and show certain repeatability. There are many different comprehension on the mechanism of such anamaly formation, of which the role of supperdistant strong earthquake precursors and the large tectonic influence on the development of such strong earthquakes are the representative ideas. Recently, the authors of this paper put forward a hypothesis that the role of atmospheric dynamics on the basis of interaction between the lithosphere and atmosphere. The new phenomena are well worth attention although the mechanism of such anomaly has not been understand yet. We need to make a systematic research on the mechanism, so as to bring about steady improvement in the train of thought on the study of earthquake prediction science. |
