| 摘 要： | 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;在丰水期地下水是混合补给,包括来自奥陶系岩溶水直接补给和硅酸盐岩裂隙水的间接补给,而在枯水期地下水主要由奥陶系岩溶水直接补给;泉群区地下水中的S主要来源于燃煤,而且有不断增加的趋势。

| Abstract: | Abstract: Groundwater is an essential source of water for socio-economical development and ecosystem maintenance in Jinan karst spring catchment. The paper analyses hydro-chemistry and isotopic data from discharge area integrating with hydro-geology setting in Jinan karst spring catchment. The synthetic approach was taken in the studies, including main ion analysis (Cl-, NO3-, Mg2+, Ca2+, HCO3-, SO42-), trace element analysis (Br, Ba, Sr), environment isotopic analysis (2H, 18O, 34S) and so on. Hydro-chemical and isotopic analysis have indicated that different sources of recharge and flow paths during drought and raining period. There are three series of springs in the catchment. Flow path of Heihu Spring is to discharge directly via the Ordovician limestone, Baotu Spring flow out via the Ordovician limestone and Quaternary sediments, and Wulong Springs, Pearl Spring and #53 well flow through the weak of quaternary sediments and contact zone between limestone and intrusive;
Groundwater in the spring catchment was recharged from the mixed water of the Ordovician karst water and silicate rock fissure water in the raining period, but it was recharged mainly from the Ordovician karst water in the dry season; Sulfur in the groundwater mainly came from use of coal, and has a rising trend. |
