摘要

摘要: 筛珠洞泉位于中低山区与渭北黄土台塬区衔接地带。筛珠洞泉区地势整体趋势为西北高东南低，北部以中低山为主，海拔在1 200～1 600 m之间，多由裸露和隐伏碳酸盐岩组成；西南地势逐渐降低，海拔在800～1 000 m之间，为以唐王陵向斜为主的一系列褶皱构造，由奥陶系碎屑岩和碳酸盐岩组成；东南部地势呈阶梯状下降，山前地带海拔多在400～500 m之间，为裸露碳酸盐岩区与山前冲洪积扇区的接触地带。筛珠洞泉作为渭北中部最大的岩溶泉，对于其补给来源前人已做了大量的研究，较为一致的认识是泾河渗漏是筛珠洞泉最主要补给来源，且筛珠洞泉是渭北中部筛珠洞泉域隐伏岩溶系统的集中排泄点。本文根据氢、氧和锶同位素的研究成果，结合水文地球化学及岩溶水文地质条件，对筛珠洞泉的补给来源提出了与前人研究不同的认识，即筛珠洞泉的补给以筛珠洞泉域外西南部岩溶地下水为主；在所有的补给来源中，大气降水、河水及岩溶水所占比例分别为11 %、37 %和52 %；在岩溶水补给中，西南部、西北部及坝址区岩溶水所占比例分别为77.9 ％、19.7 ％和2.4 ％。在此基础上，本文还根据氚同位素资料估算筛珠洞主泉岩溶水的平均滞留时间为62～64年。

Abstract: Shaizhudong spring is located between middle-low mountains and Weibei loess tablelands. The overall terrain trend of the study area is that it is higher in the northwest than in the southeast.The north area is mainly middle-low mountains with elevations of about 1 200 to 1 600 m, and it mainly consists of exposed or concealed carbonate rocks. In the southwest the terrain gradually decreases, with altitudes of 800 to 1 000 m, and a series of Tangwangling synclinal fold structures consisting of Ordovician clastic and carbonate rocks. The terrain of the southeast area shows a ladder-like decrease and the elevation of the piedmont zone is between 400 and 500 m, which is located between exposed carbonate area and piedmont alluvial-pluvial fan sector. Shaizhudong spring is the largest karst spring in central Weibei, Shaanxi Province, China. Its supply source has been the topic of a lot of research, and it was thought that Jinghe leakage was the main recharge source, and it was the main discharge point in the hiden karst system of shaizhudong spring area. In this paper, we have a different understanding of the recharge of Shaizhudong spring, based on research into hydrogen, oxygen and strontium isotopes, combined with hydro-geochemistry and karst hydrogeological conditions. Isotope hydro-geochemistry study showed that the recharge was given priority to karst groundwater outside southwest of the Shaizhudong spring area. The proportions of atmospheric precipitation, river water and karst water were 11 %, 37 % and 52 % of all the supply source, and proportion in the southwest, northwest and the dam site area karst water were 77.9 %, 19.7 % and 2.4 % in the karst water supplies, respectively. On this basis, this paper also estimates that the average residence time of Shaizhudong spring karst water is 62-64 years based on tritium isotope data.
