摘　　要：以新04井静水位为研究对象,分析气温、气压和地下水理论固体潮对新04井静水位的影响特征,并探讨其机理。结果表明:①气温、气压对新04井静水位长趋势变化和短周期变化影响均比较大,而地下水固体潮对新04井静水位变化影响很小;②气温是静水位年变化最主要的影响因素,表现为中高度线性负相关,参与计算的2段观测数据中,2007-01-01~2011-08-31时段水位相位滞后气温约35 d,2017-01-01~2019-12-31时段水位相位滞后约15 d;③气压是静水位短周期变化的主要影响因素,影响方式以短周期微动态干扰导致的畸变为主,表现为中高度线性正相关。Taking the static water level of well Xin 04 as the research object,the influence characteristics of air temperature,air pressure and groundwater theoretical solid tide on the static water level of well Xin 04 are analyzed,and its mechanism is discussed.The results show that:①air temperature and air pressure have great influence on the long-term trend and short-term change of static water level of well Xin 04,while groundwater solid tide has little influence on the change of static water level of well Xin 04;②Air temperature is the most important factor affecting the annual change of still water level,which shows a medium height linear negative correlation.In the two observation data involved in the calculation,the phase lag of water level is about 35 days from January 1,2007 to August 31,2011,and about 15 days from January 1,2017 to December 31,2019;③Air pressure is the main factor affecting the short-term change of still water level.The influence mode is mainly the distortion caused by short-term micro dynamic interference,which shows medium and high linear positive correlation.
