内蒙古自治区兴和县地下水开采引起的地质环境问题研究

摘要

In order to analyze geological environment problems caused by groundwater exploitation in Xinghe County , Inner Mongolia, using field investigation and interview, the change of agricultural irrigation area, the Quaternary aquifer distribution area and underground water lev-el, water quality was investigated.The results showed that the groundwater level in the agricultural irrigation area decreased significantly, the shallow layer of the Quaternary aquifer appeared unwatering.Aiming at the investigation results, it was proposed that in the future we should make use of surface water resources and take measures to save water , so as to achieve the goal of reducing the irrigation quota and slowing down the decreasing trend of groundwater level.%为了分析内蒙古自治区兴和县地下水开采引发的地质环境问题，采用实地调查和访问的方法，调查该地区农灌区、第四系含水层分布区和地下水位、水质历年变化情况。结果表明：农灌区地下水位大幅下降，浅层第四系含水层局部地区出现了疏干。针对调查结果，提出今后应当充分利用地表水资源并采取节水措施，节约地下水资源，以达到降低灌溉定额及减缓地下水水位下降趋势的目标。
