河北省平原区地下水水位年内动态类型特征

Dynamic types of groundwater level during the year in the plain area of Hebei Province

地下水水位的变化受补给和排泄影响,研究地下水水位动态特征和变化趋势,有利于地下水的可持续开发利用。应用Excel软件对河北平原区年内地下水水位动态监测数据进行了分析,结果表明河北平原区浅层地下水动态类型为降水入渗―开采型、降水入渗―蒸发型、河渠水渗漏―径流型和降水入渗―开采越流型。深层地下水动态类型为径流―开采型和越流—开采型。

The change of groundwater level is affected by recharge and discharge.Studying the dynamic characteristics and changing trend of groundwater level are beneficial to the sustainable development and utilization of groundwater.The Excel software was used to analyze the dynamic monitoring data of groundwater level during the year in Hebei Plain area,and the results showed that the dynamic types of shallow groundwater in the Hebei Plain area are precipitation infiltration-mining,precipitation infiltration-evaporation,river and canal water leakage-runoff and precipitation infiltration-mining,cross flow types.The dynamic types of deep groundwater are runoff-mining and cross flow-mining types.
