| 摘 要： | 在系统清理温泉台新30号观测井水温度20多年观测资料的基础上，归纳出新30井新、旧观测点井水温动态的多年趋势和年、月、日动态类型，并对其特征进行分析。多年动态类型为下降—阶变型和下降型，年动态类型为平稳—下降型，月动态类型为平稳—下降型和平稳—上升型，日动态类型为随机起伏型。影响水温动态类型的因素有地表水的侧向补给、邻井地下水开采及观测井内的井水扰动等，此外仪器本身的不稳定性对动态类型也产生重要影响。排除各种干扰之后，仍发现井水温度有较好的映震效应。该井水温以同震或震后效应为主，对附近的中、小地震在震前也有一定的异常显示。

| Abstract: | On the basis of cleaning up water temperature observation data more than 20 years in new 30 well systemically, the dynamic tendency in many years, the annual, month and daily dynamic type was summarized and the characteristic was analyzed. The dynamic types in many years were dropping - staging and drop; annual dynamic type was steady dropping; month dynamic type was steady - dropping and steady rising and daily dynamic type was ups and downs randomly. At present the main factors influencing water temperature dynamic types were the surface water lateral supplies, ground water mining in adjoining well and water perturbation in the observation well and so on. In addition, instrument＇s instability also has the materi effect to the dynamic type. Knowing the above normal dynamic type, after removing each kind of disturbance, we found that the well water temperature had good earthquake reflecting effect, the water temperature showed co seismic and after-quake effect primarily, and before some near small-moderate earthquakes there was still precursor anomaly in some extent. |
