摘　　要：通过对克什克腾井水位、水温多年观测资料分析,研究水温微动态的形成机制及其影响因素,结果表明:该井水温呈现冬高夏低的动态变化,且呈逐年下降趋势;该井水温独特的动态与典型的降雨补给影响有所不同,水温的变化与水位变化及降水补给时间均不同步,研究认为距离该井较远的大气降水补给区和热水在含水层较长的停留时间是引起水温动态与降雨补给不同步的可能原因。The formation mechanism and influencing factors of water temperature microdynamic are studied by analyzing the observation data of water level and water temperature in Keshiketeng well for many years.The results show that the water temperature of the well shows a dynamic change of high in winter and low in summer,and shows a downward trend year by year.The unique dynamic of the water temperature of the well is different from the impact of typical rainfall recharge.The change of water temperature is not synchronized with the change of water level and precipitation recharge time.It is considered that the atmospheric precipitation recharge area far away from the well and the long residence time of hot water in the aquifer are the possible reasons for the non-synchronization between water temperature dynamics and rainfall recharge.It is reasonable to use the lag effect of rainfall recharge and geothermal dynamics to explain the microdynamic change of water temperature in the well.
