摘要
Particular attestation has been drawn in recent years to the relationship between recharge, runoff and drainage of groundwater in the water research on the red beds. 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 geomorphologic features are believed to be the main controlling factors for the enrichment of groundwater.
