华北平原深层地下水可更新性与水位管控探讨
Discussion on renewability of deep aquifer and water level control in the North China Plain
摘要
Abstract
Based on the existing researches,discussions are made on the changes of deep aquifer circulation and recharge and drainage paths in the North China Plain under the effect of large-scale development and utilization.It demonstrates that deep aquifer has certain renewability under mining conditions from the aspects of vector field test in front of mountains,synchronization of shallow and deep groundwater level changes,downward movement of salt and fresh water interface,groundwater age and hydrochemical analysis.With analysis of relationship between renewability and exploitability,it is found that although the aquifer has certain renewability,the exploitation of groundwater in the North China Plain should be strictly controlled to avoid geological environmental risks.The study proposes a threshold for controlling the water level of deep aquifer when groundwater extraction is necessary,so as to provide insights for the utilization and protection of deep aquifer.关键词
