摘要
地下水位动态变化受降水、地表水入渗、人工开采、侧向径流和水文地质条件等多种因素影响,加之人类活动对地下水天然流场的干预程度较大,逐渐呈现出更加复杂化的动态特征。为对河北邯郸东部平原区地下水位动态特征进行研究,在对该区域水文地质条件分析的基础上,结合2018年度国家地下水监测工程深浅层监测井的自动监测数据和降水、蒸发、开采量等相关统计资料,对平原区第四系孔隙水的动态特征进行了分析,总结得2018年度地下水位动态变化规律及其成因类型。结果显示:邯郸市平原区的地下水位动态特征可分为降水-开采型;越流-开采型;降水、侧向径流-开采、蒸发型和河流入渗型四种类型。随着人类活动对地下水天然流场的干预越来越大,使得平原区地下水动态呈现出更加复杂化的动态特征。
The dynamic change of groundwater level is influenced by many factors such as artificial mining lateral runoff and hydrogeological conditions because the infiltration of precipitation surface water,also the intervention degree of human activities on the natural groundwater flow field,which gradually presents more complicated dynamic feature.For hebei handan city eastern plains of the underground water level dynamic feature are studied,on the basis of analyzing the regional hydrogeological conditions,combined with the 2018 national groundwater monitoring project layer depth monitoring Wells automatic monitoring data and related statistical data,as precipitation evaporation production was get on the investigation on dynamic feature of the quaternary pore water analysis,summed up the 2018 underground waterlevel dynamic variation and its genetic type.The results show that:the dynamic feature of groundwater level in plain area of handan city can be divided into precipitation mining type.Overflow type;There are four types of precipitation lateral runoff mining evaporation type and river infiltration type.
