| 摘 要： | 本文主要通过对安徽大王洞各采样点水质的分析,揭示大王洞地下水化学组成,进而揭示地下河水的物质来源及污染状况。结果表明,地下河水中Ca2+、Mg2+、HCO3-主要来自碳酸盐岩的溶解,土壤和岩石的元素通过岩溶地球化学过程向水中迁移致使水中存在大量元素,Ca2+在阳离子中占主导地位,HCO3-在阴离子中占主导地位,K+、Na+、NO3-、SO42-、Cl-浓度较高,明显受到人为污染影响,Ca2+与HCO3-,EC与TDS、Ca2+、HCO3-,Na+与SO42-、Cl-表现出了较强的相关性。整个地下河水主要由洞外水、支流水、滴水汇聚而成,洞外水、支流水、滴水对地下河水的贡献量约为62%、23%、15%。

| Abstract: | The chemical compositions and sources of undergroundwater and its mineralization and pollution in the Dawang Cave are described in this paper.The results of sample analysis showed Ca2+,Mg2+ and HCO3-in cave groundwater were derived mainly from the dissolution of carbonate rocks.The elements of soils and rocks were transferred to water via karst geochemistry process,resulting in the existence of abundant elements in cave water.Ca2+ was the dominant cation in water,while the HCO3-was the dominant anion.The hi... |
