系统分析临潼地震台水温20多年的连续观测数据变化特征，提取水温的正常动态与异常形态，及其与远、近场地震的关系，取得以下结果：水温具有较规则的夏高冬低的年周期动态特征，初步分析认为与周期性开采量变化有关，属于正常动态；持续上升—转折下降以及年周期消失属于异常动态；异常动态与青藏块体及其周缘M≥7.5远场大震以及该台所处的渭河盆M_L≥4地震存在较好的相关性。结果对揭示1988年以来青藏高原块体的地球动力学条件具有一定的指示意义。

In this paper, we systematically analyzed the variation of water temperature of daily observations during 20 years in Lintong observatory. The normal dynamic and abnormal dynamic of water temperature was extracted and the relationship between water temperature dynamic and the earthquake of far、near-field（respectively around the Tibetan Plateau block and Lintong observatory）are present here. The preliminary study can be concluded as the following aspects: Water temperature has a almost regular annual cycle with high variation in summer and low variation in winter, and then initial analysis showed that it is related with the cyclical extraction. Therefore，it belongs to normal dynamic;The variation that Water temperature continues to rise, then turn down and disappear of annual cycle belongs to abnormal dynamic;There is a good correlation between abnormal dynamic and the far-field earthquake of M ≥ 7.5 in Tibetan Plateau block. Also, there is a good correlation between abnormal dynamic and the near-field earthquake of ML>4 in the Weihe River basin where the observatory is located. Our approach provides a reference for revealing the geodynamic conditions of the Tibetan Plateau Block since 1988.
