摘要
兴平市地下水位监测工作已经开展了40多年,监测区覆盖了全市所辖5个街道、8个镇。依据2007~2017年11年地下水位监测资料,对黄土塬区和渭河阶地区浅层地下水位动态变化及其影响因素进行了分析,认为:1)兴平市地下水位动态受水文地质条件、降水和开采条件的影响,不同地貌单元地下水位动态变化和影响因素各不相同;2)多年来,兴平市地下水位总体呈下降趋势,兴平化肥厂水源地,水位下降幅度更大;3)近十年来,兴平市和兴平兴化一般超采区地下水位总体均趋于稳定略有下降,下降区集中分布在兴平市西部地区。4)兴平市地下水位动态主要受降水量和开采量的影响。
Groundwater Monitoring has been carried out in Xingping city for more than 40 yearscovering five streets and eight towns.The dynamic changes and influencing factors of shallow groundwater level are studied in the loess tableland and Weihe -River terraceaccording to the monitoring data of groundwater level from 2007 to 2017.The study results show that:1) the groundwater level dynamics in Xingping city are mainly controlled by the hydrogeological conditions,atmospheric precipitation and exploitation density.The dynamic changes and influencing factors of groundwater level vary with different geomorphic units ;2)the groundwater level in Xingping city declined continuously over the years,the depression might be even deeper in thegroundwater supply sites of Xingping chemical fertilizer plant;3)the groundwater level in Xingping and the general groundwater overdraft area of Xingping chemical fertilizer plant was generally stable and decreased slightly in the past ten years,the decrease area was concentrated in the western part of Xingping city ;4)the dominant factors influencing the groundwater level in Xingping city is atmospheric precipitation and exploitation density.
