昌黎井数字化水温具有比较规律性的多年变化动态趋势，在一场地震发生前、中、后地下水含水层由于受到地下地质环境变化的影响，水温资料往往显现出比较明显的震前、震中、震后异常。通过整理分析昌黎井水温资料，分析昌黎井水温前兆异常变化，得出昌黎井水温变化机理和映震机理，为今后充分发掘昌黎井水温所包含地震前兆信息提供帮助。

The digital water temperature of Changli well have regular dynamics trend for many years. Before, during and after the occurrence of an earthquake , the groundwater aquifers were impacted by the underground geological environment changes, so the data of water temperature was showed more obvious abnormal before the earthquake、 epicenter and after the earthquake.In this paper, by collated and analyzed Changli well water temperature data, analyzed the water temperature abnormal precursor changes of changli well. Reach conclusion that the mechanism of water temperature changes and reflect the earthquake for changli well.It was helpful to fully explored the precursor information which contained from the water temperature of changli well in the future.
