| 摘 要： | 鄂尔多斯市地处半干旱区,水资源缺乏,监测地下水位的变化对于地区生态和经济发展具有重要意义。本研究利用鄂尔多斯市6个地下水位监测井2005-2014年的监测资料,分析了该地区地下水位变化特征。结果显示:(1)本地区地下水位2005-2006年有所下降,2007-2010年逐年抬升,2011年受严重干旱影响,地下水位为近10年来最低值,从2012年开始至2014年,以每年0.14 m的幅度抬升,2014年为近10年最高值,地下水位的年际变化主要与煤炭开采和经济发展有关。(2)地下水位的年内季节变化明显,与降雨量、蒸发量和农业灌溉用水的相关性较高。3-7月,水位持续下降,7月地下水位为年内最低点;8-10月,水位逐步回升;11月至次年2月水位总体呈略微抬升状态,次年2月为年内最高值。

| Abstract: | Ordos is located in the semi-arid area of China, and is scarce of water resource. To monitor the variation of groundwater level is important for ecological and economic development in the region. In this study, variation of groundwater level in the region was analyzed based on data collected by six groundwater level observation stations from 2005 to 2014. The results show that: (1) The average groundwater level decreased from 2005 to 2006, increased from 2007 to 2010, and declined to minimum level in 2011 since the severe drought. It was uplifted gradually from 2012 to 2014 at a rate of 0.14 m every year, and came to the highest value in 2014 among the past 10 years. (2) Seasonal change of groundwater level was obvious in the region. The groundwater level continuously declined from March to July, and the groundwater level was the lowest in July. The groundwater level was gradually raised from August to October. The groundwater level was slightly elevated from November to February in the following year and came to the highest value in February. Seasonal change of groundwater level was closely correlated with rainfall and evaporation. |
