摘要
通过对莱芜盆地牟汶河流域附近不同水体进行取样,采用氢氧同位素进行分析,初步研究了牟汶河流域上游不同类型地下水氢氧同位素分布特征,分析了地下水补给来源及循环机理。研究结果表明:莱芜盆地东部牟汶河上游地区,松散岩类孔隙水、岩浆岩变质岩类裂隙水补给来源主要为大气降水,地下水循环速度较快;岩溶水除接受大气降水补给外,还接受其他类型地下水间接补给;整体上研究区内地下水循环更新速度较快,均为0~10年左右新水。
Through collecting different waterbody samples near the Mouwen river in Laiwu basin,the hydrogen and oxygen isotopes distribution characteristics of different types of groundwater in the upper reaches of the Mouwen river have beem stuidied,and the supply sources and the circulation mechanism of the ground have been analyzed.As showed by the study results,in the the upper reaches of the Mouwen river,the supply sources of the unconsolidated sediment pore water,the magmatic rock and the metamorphic rock fissure water are rainfall,the groundwater circulation rate is fast.The supply sources of karstic water are rainfall and other different types of groundwater.In general,the groundwater circulation rate is new water less than 10 years in the study area.
