| 摘 要： | 江西兴国县地下水中富含偏硅酸，水资源丰富，但对矿泉水资源禀赋等研究相对薄弱，开展该县偏硅酸矿泉水水化学特征和健康功能研究，可为当地发展矿泉水产业、实施乡村振兴战略提供基础支撑。本文应用数理统计、水化学分析、离子比值等多种分析方法研究了兴国县潜在偏硅酸矿泉水的分布、水化学特征以及成因与物质来源，并基于感官指数和健康指数对其健康功能进行了评价。结果表明：潜在偏硅酸矿泉水主要分布在岩浆岩裂隙含水岩组、碎屑岩孔隙裂隙含水岩组和变质岩裂隙含水岩组中，这三类含水岩组的调查水样中，发现潜在偏硅酸矿泉水的比例分别为48.5%、45.7%、29.6%，且主要分布在海拔400m以下区域。潜在偏硅酸矿泉水的偏硅酸含量多集中在32~40mg/L之间，主要来自硅酸盐矿物的水解；在变质岩、岩浆岩裂隙含水岩组区，偏硅酸的富集以溶滤作用为主；在碎屑岩孔隙裂隙含水岩组区，偏硅酸的富集受溶滤作用和阳离子交替吸附作用共同影响。该县岩浆岩裂隙含水组区潜在偏硅酸矿泉水口感最佳，深层碎屑岩孔隙含水组区潜在偏硅酸矿泉水健康指数相对较高。本文认为，兴国县矿泉水勘查开发靶区宜以岩浆岩裂隙含水岩组区和深层碎屑岩孔隙裂隙含水岩组区为主。研究成果可为揭示兴国县偏硅酸矿泉水资源价值和功能提供参考。

| Abstract: | BACKGROUND: The groundwater in Xingguo County is rich in metasilicic acid, but the research on the endowment characteristics and genetic mechanism of mineral water resources is relatively weak, which restricts the development of the mineral water industry in Xingguo County to some extent. Research on the chemical characteristics and health functions of metasilicate mineral water in the county provides basic support for the development of the local mineral water industry and the implementation of a revitalization strategy.OBJECTIVES: To summarize the distribution characteristics of metasilicate mineral water in Xingguo County and evaluate its health function.METHODS: Mathematical statistics, water chemistry analysis, ion ratio and other analytical methods were used to study the distribution, water chemistry characteristics, genesis and material sources of potential metasilicate mineral water in Xingguo County, and its health function based on sensory index and health index was evaluated.RESULTS: Potential metasilicate mineral water was mainly distributed in the area below 400m above sea level, and it was distributed primarily in a magmatic rock fissure water-bearing rock formation, a clastic rock pore fissure water-bearing rock formation and a metamorphic rock fissure water-bearing rock formation. In the investigated water samples of these three types of water-bearing rock formations, the proportion of potential metasilicate mineral water was 48.5%, 45.7% and 29.6%, respectively. The metasilicic acid content of potential metasilicate mineral water was mostly between 32 and 40mg/L, mainly from the hydrolysis of silicate minerals. The enrichment of metasilicic acid was caused by solution filtration in the metamorphic rock and magmatic rock fracture water-bearing formation area, and was jointly affected by solution filtration and cation alternating adsorption in the clastic rock pore fracture water-bearing formation area. The potential metasilicate mineral water in the magmatic rock fracture water-bearing group area had the best taste, and the deep clastic rock pore water bearing group area had a relatively high health index.CONCLUSIONS: The results of this study suggest that the target area of mineral water exploration and development in Xingguo County should be in magmatic rock fissure water-bearing rock formation areas and deep clastic rock pore fissure water-bearing rock formation areas. The research results provide reference for revealing the value and function of metasilicate mineral water resources in Xingguo County. |
