摘要
分析济南幅黄泛平原区浅层孔隙水的补给来源、地下水流场形态变化、地下水排泄途径及水化学多年变化特征,并结合区内浅层地下水开采强度资料综合研究认为,引起济南幅黄泛平原区浅层孔隙水动力场变化的主要原因是地下水开采量的变化与天然补给源的减少。研究表明,局部水位下降甚至产生超采漏斗主要是由于地下水长期过量开采引起的,并对区域地下水流场形态影响较大,区内已形成地下水分水岭。
On the basis of analyzing the source of groundwater recharge,the change of groundwater flow field,groundwater discharge,and characteristis of hydro-geochemical changes,combing with comprehensive study on exploitation intensity of shallow groundwater,it is reagrded that hydro-dynamic field change of shalllow pore water in the flood plain of the Yellow River is mainly caused by the change of groundwater with drawal and decrease of nature recharge source.The down of groundwater level and funnels are mainly cause by over exploitation of groundwater.It also influenced regional groundwater flow field,and formed groundwater watershed in this areas.
