| 摘 要： | 本文在分析铀的水文地球化学特征的基础上，以滇西及甘肃河西两地区部分泉水中铀的动态变化资料为依据，研究了地下水中铀含量变化与上述地区中强地震发生的关系。结果表明，在一定条件下，地震前铀含量异常变化是明显的。本文还对地下水中铀含量异常机理及干扰因素等进行了研究，提出了由于泉点所处地球化学球境的差异，铀异常并非普遍存在，只有活性铀在地下水或围岩中含量较高的水点，才适合于进行铀含量的观测。另外，本文还采用对比观测方法，首次对地下水中铀含量异常与氡含量异常之间关系及水氧异常机理作了新的解释，对利用水中铀含量异常预报地震的可行性进行了论证。

| Abstract: | Based on the analysis of hydrogeochemical features of Uranium,in terms of the data ofdynamic variation of Uranium in some springs in the western Yunnan and Hexi corridor,Gansu,this paper studied the relation between the content variation of Uranium in ground-water and moderately strong earthquakes in these areas.The result shows that the anoma-lous variation of Uranium content is obvious under some circumstances.By analysing the anomalous mechanism of Uranium content in groundwater and theinterference factors,it is suggested that the Uranium anomaly doesnot commonly occur be-cause of the differences of gochemical conditions around the springs, and only the springswith high content of activated Uranium in groundwater and wall rock are suitable to obser-vation of Uranium content.with the method of comparative observation, the interpretation is tried, for the first-time,on the relationship between the content anomaly of groundwater Uranium and that ofgroundwater Radon,and on the mechanism of Radon anomaly in groundwater. The feasi-bility of earthquake prediction with groundwater Uranium anomaly is also dealt with. |
