济南岩溶泉域泉群区水化学与环境同位素研究

本文通过对济南岩溶泉域排泄区地下水样品的分析,采用主要离子(Cl、NO_3、Mg、Ca、HCO_3、SO_4)、微量元素(Br、Ba、Sr)、氢氧同位素(~2H和~(18)O)、硫同位素(~(34)S)等示踪因子的综合研究方法,结合岩溶泉域实际水文地质条件,揭示了济南泉水的水文地球化学特征、枯丰期水化学动态和环境同位素特征,确定了泉水在枯、丰水期不同的补给来源及补给途径。研究显示,泉群区出流的泉水可以分为三组,黑虎泉出流的路径是经奥陶系灰岩直接出流,趵突泉是经奥陶系灰岩与第四系沉积层出流地表,而五龙潭泉、珍珠泉和53号井则是在灰岩和侵入岩体的接触地带及第四系沉积层较薄弱处涌出地表;在丰水期地下...

Groundwater is an essential source of water for socio-economical development and ecosystem maintenance in karst spring catchment in Jinan. The paper analyzed hydro-chemistry and isotopic features for the samples from discharge area in the karst spring catchment using tracers such as ions (Cl, NO3, Mg, Ca, HCO3 and SO4), trace elements (Br, Ba and Sr) and sulfur isotope (34S), coupled with hydrological and geological background of this area. Hydro-chemical and isotopic analysis reveals different sources of recharge and flow paths during drought and raining periods. There are three series of springs in the catchment. Flow path of Heihu Spring is to discharge directly from the Ordovician limestone, Baotu Spring flow out from the Ordovician limestone and Quaternary sediments, and Wulong Springs, Pearl Spring and # 53 well flow through the
