| 摘 要： | 包气带是降水补给地下水的一个主要环节,是了解补给变化的地质信息载体。以滹沱河冲洪积扇河北省正定试验场包气带剖面为研究对象,利用环境示踪剂(氚和氯)方法,估算了该区地下水近三十多年来的天然补给强度。研究结果表明:近30年来天然降水平均补给强度约为0.089m/a,在天然条件下该区降水垂直运移速度约为0.6m/a,其变化趋势主要受降水量变化影响,并表现出一定的滞后性。

| Abstract: | Estimation of groundwater recharge is one of the important scientific issues for sustainable development and management of water resources.However,the large spatial and temporal variation makes it difficult to measure directly the groundwater recharge rate and hence it is very difficult to reconstruct the groundwater recharge history and estimate the changes of recharge rate.Unsaturated zone,as a link between precipitation and groundwater recharge,may contain information about recharge.This paper discusses ... |
