以民勤2001-2014年52眼观测井连续观测的地下水埋深、地下水矿化度数据为基础,分析地下水埋深及其矿化度的时空变化规律,与已采取的治理工程措施做了相关性分析.结果表明:空间上地下水埋深以泉山区最大,南湖区最小;地下水矿化度排序表现为湖区>泉山区>坝区>南湖区;时间序列上,地下水埋深先增加(2001-2009年)后维持平稳并有减小的趋势(2010-2014年),地下水月变化特征整体呈V字型;地下水矿化度先变大(2001-2012年)后减小(2012-2014年),湖区和南湖区的地下水矿化度秋季大于春季,泉山区和坝区的春季大于秋季;地下水埋深及其矿化度与采取的治理工程具有显著相关性.
Based on the continuous observation of groundwater depth and groundwater salinity data from 52 observation wells in Minqin during 2001-2014, the temporal and spatial variation of groundwater depth and its salinity were analyzed and related to the engineering measures taken The results show that the spatial depth of groundwater is the largest in Quan Mountain and the smallest in Nanhu District, and the order of groundwater salinity is Lake District> Quanshan District> Dam District> Nanhu District. In time series, groundwater depth first increases (2001- (2010-2014), the monthly variation of groundwater was V-shaped in general; the salinity of groundwater first increased (2001-2012) and then decreased (2012-2014 ). The salinity of groundwater in Lake District and Nanhu District was greater in spring than in spring, while that in Quanshan District and dam area was higher than that in autumn. The groundwater depth and its salinity were significantly correlated with the treatment projects.
