近50年衡水市浅层地下水位动态特征分析

摘要

自20世纪50年代后期，衡水市浅层地下水被大规模开采利用。依据衡水市1968~2014年的浅层地下水埋深观测资料，分析了近50 a来该地区地下水位的动态变化过程，得出地下水水位累计下降9.35 m，地下水埋深最大的安平县达到32.6 m。选用地学统计克里格插值法，应用 Surfer软件绘制地下水埋深分布图，着重分析多年来地下水埋深的区域分布特征及变化规律。分析了地下水水位降落给生态环境带来的影响，提出了全面加强水源保护涵养等切实有效的对策措施。%Since 1950s. According to the Observational data of shallow groundwater depth in Hengshui City from 1968 to 2014,It’s the analysis of groundwater level dynamic processin in the region in recent 50 years. It′s a conclusion that the ground-water level dropped by 9. 35m,that the groundwater depth reached 32. 6m in Anping County. Using geostatistics Kriging interpo-lation method,application of surfer software drawing groundwater buried depth distribution map. Analysis of regional distribution characteristics and variation of groundwater depth over the years. Analysis of the impact of the groundwater level fall to the ecolog-ical environment,and put forward the effective measures to strengthen the protection of water resources,and so on.
