目的:研究凤山县鸳鸯泉的水文地质成因,为鸳鸯泉这一地质奇观提出科学的解释。暰方法暱根据实地调查和现场试验,结合地层岩性、地质构造以及岩溶发育情况,查明鸳鸯泉的岩溶水文地质条件;根据地下水示踪试验,确定鸳鸯泉的源头和主要的岩溶含水介质类型,并通过稳定氢氧同位素和钙锶比(Ca/Sr)分析,研究管道介质岩溶大泉的补径排过程和水循环特征。结果:鸳鸯泉的源头为年里落水洞补给的外源水,公塘和母塘两个出口的主径流管道基本一致;鸳鸯泉具有以岩溶管道为主的含水介质特征,以及快速流的补给、径流和排泄过程。这种水文地质现象的成因与管道流集中排泄的方式有关。结论:鸳鸯泉同属于一个管道系统,管道流的两个出口在水循环速度上存在差异,相比公塘,母塘具有较短的径流途径和较快的更新速率。
Objective: To study the hydrological geology of Yuanyangquan in Fengshan County and to provide a scientific explanation for the geological wonders of Yuanyangquan.暰 Methodology According to field investigation and field test, the karst hydrogeological conditions of Yuanyangquan were identified according to lithology, geological structure and karst development. According to groundwater tracing test, the source of Yuanyanquan and the main types of karst aqueous media , And through the analysis of stable hydrogen and oxygen isotopes and calcium-strontium ratio (Ca / Sr), the filling process and the water cycle characteristics of the karst springs in pipeline media were studied. Results: The origin of Yuanyangquan is the exogenous water supplied by the water hole in the year. The main runoff pipes of the two outlets of Gongtang and Tong are basically the same. Yuanyangquan has the characteristics of karst-dominated aqueous medium and the supply of rapid flow , Runoff and excretion processes. The causes of this hydrogeological phenomenon are related to the way in which pipelines concentrate and excrete. Conclusion: Yuanyangquan belongs to one pipeline system. There are differences in water circulation velocity between the two outlets of the pipeline flow. Compared with the public pond, the mother pond has shorter runoff path and faster update rate.
