| 摘 要： | 典型红层严重缺水地区地下水补径排的关系如何？浅表层分化裂隙水补给来源和途径如何？是我们在实施红层找水工作中最为关心的问题。本文以重庆荣昌县为研究区，结合地下水1：5万水文地质调查工作，采用氢氧同位素测年方法，较为系统地研究了地下水的补给、径流、排泄循环关系和地下水储存规律，得出红层浅层地下水主要补给为大气降水，其次是地表水体。具有就地补给、就近排泄的循环特点。地下水总的富集规律是低山、岭、丘贫水，沟、谷、洼地富水。地貌是浅层地下水富集的主控因素。

| Abstract: | Particular attentation has been drawn in recent years to the relationship between recharge, runoff and drainage of groundwater in the water research on the red beds. Examplified by Rongchang in Chongqing, the relationship between recharge, runoff and drainage of groundwater is explored, in detail, on the basis of hydrogen and oxygen isotopic dating in integration of the 1：50 000 hydrogeological survey. It is concluded that the shallow groundwater in the red beds is derived dominantly from meteoric water, and subordinately from surface water. The groundwater in the study area has the features of recharge in situ and discharge nearby, and exhibits a trend of the depletion in mountains, ridges and hills and enrichment in gullies, valleys and swales. The geomorphological features are believed to be the main controlling factors for the enrichment of groundwater. |
