天津平原区地下水位动态特征与影响因素分析

摘要

The groundwater monitoring in Tianjin has been conducted for nearly 40 years.The monitoring area includes the whole plain region.Based on the monitoring data of the groundwater level of many years,this paper analyzes and studies the groundwater regime characteristics and effect factors of the shallow groundwater and the groundwater in the deep-seated aquifers.It is concluded that,groundwater level regime is controlled by hydrogeology condition,precipitation and mining in the plain region of Tianjin city,different groundwater regime regularity shows the obvious difference in space and time,and in addition to some natural factors,such as the precipitation and temperature etc.,mining groundwater is the main factor to affect the groundwater level regime.%天津市地下水位监测工作已经开展了将近40年,监测区覆盖整个平原区。根据多年地下水位监测资料,笔者对区内浅层地下水和深层地下水不同含水层组的水位动态特征及其影响因素进行了分析研究,认为：天津平原区地下水位动态受水文地质条件、降水和开采条件的控制,不同类型地下水动态规律在时空分布上有明显差异,除降水量、温度等自然因素外,开采地下水是影响地下水位动态变化的主要因素。
