摘 要:关中城市群地下水自集中开采以来区域地下水位呈整体下降趋势,主要城市集中供水水源地水位降幅30~50m,最大超过120m。长期过量开采地下水引起了地下水位持续下降、地面沉降、地裂缝以及水质污染等环境地质问题。近年随着城市群限制开采量,地下水水位下降及其相关环境地质问题在局部地段有所缓和。本文以50年地下水动态监测数据为基础,针对关中城市群地下水动态特征及相关的环境地质问题进行研究分析,并对预防和缓解环境地质问题、合理开发地下水资源提出建议。The ground water level has been declining since the concentrated exploitation of groundwater in Guanzhong urban agglomeration. The declining amplitude of it is 30 - 50m in major water source, with a maximum more than 120 m. Long term excessive exploitation of groundwater has caused a continuous decline in groundwater level, ground subsidence, ground fissure, water pollution and other environmental geological problems. In recent years, the exploitation control on groundwater in urban agglomeration is relieving the continuous decline in groundwater level and the related local environment geological problems. This paper based on 50 year monitoring data of groundwater dynamics, studied in dynamic characteristics of groundwater and related environmental geological problems, proposed suggestions for prevention and mitigation of environmental geological problems and development of groundwater.
