摘要
通过对衡水市深层地下水开采量及变化特征分析,为地下水压采提供科学依据。采用水利统计的方法,利用衡水市2001~2014年地下水开采量资料,分析其变化特征。衡水市各县(市、区)深层地下水位呈下降趋势。衡水市地下水埋深平均每年下降1.25 m。地下水埋深下降最大的为景县前村地下水测井,地下水埋深平均每年下降1.67 m;地下水埋深下降最小的为安平县小辛庄地下水测井,平均每年下降0.79 m。由于对地下水的连续超采,已造成多项环境地质灾害。表现明显的有地下水水位降落漏斗、浅层地下水含水层疏干、地裂缝、地面沉降、咸水界面下移、咸水入侵等地质灾害。
According to the analysis of characteristics of deep groundwater exploitation and changes in Hengshui City, this article provided scientific basis for groundwater exploitation. By using the method of water conservancy statistics and the data of groundwater exploitation in Hengshui city from 2001 to 2014 , we analyzed its changing characteristics. Groundwater table has been declining in Hengshui city counties (cities, districts). The average annual decline rate of groundwater depth in Hengshui city is 1. 25 m. The groundwater depth decline rate is the biggest in Qian village water log-ging of Jingxian County , its average annual decline rate is 1. 67 m. The groundwater depth decline rate is the smallest in Xiaoxinzhuang water logging of An Ping county, its average annual decline rate is 0. 79 m. The continuous exploitation of groundwater has caused a number of environmental geolog-ical disasters, such as : groundwater table decline funnel, shallow groundwater aquifer dewatering, ground fissure, land subsidence, saltwater interface down, saltwater intrusion and so on.
