| 摘 要： | 基于海南省东部和南部海岸带地区地下水现场监测数据和室内水化学测定数据,研究了各水化学指标间的相关性,分析了区域海水入侵现状。研究结果表明地下水中Cl~–与Na~+的变异系数较高,与矿化度(TDS)具有强的相关性;以m(Cl~–)(m表示质量浓度)和TDS分别作为评价因子开展了海水入侵现状评价,结果表明研究区域内地下水未受到海水入侵的影响;m(Na~+)/m(Cl~–)、 m(Cl~–)/m(HCO_3~–)、m(Cl~–)/m(SO_4~(2–))、m(Ca~(2+))/m(Na~+)、m(Ca~(2+))/m(Mg~(2+))、钠吸附比(SAR)与m(Cl~–)的相关性分析结果表明m(Na~+)/m(Cl~–)、m(Ca~(2+))/m(Na~+)、m(Ca~(2+))/m(Mg~(2+))以及SAR4个参数可以作为海南省海水入侵判定的评价因子。研究结果对建设海南省"国际旅游岛"战略目标,指导当地合理利用地下水具有参考价值。

| Abstract: | Based on the field monitoring and indoor water chemistry measurement data from the coastal areas of eastern and southern Hainan Province, this paper studied the correlation among various water chemistry indexes and analyzed current regional seawater intrusion. The results showed that the variation coefficient of Cl- and Na+ in groundwater was high and correlated strongly with total dissolved solids (TDS). The current evaluation of seawater intrusion was conducted using m(Cl-) (m is mass concentration) and TDS as evaluating factors. Results showed that inland water was unaffected by seawater intrusion. The correlation analysis results of m(Na+)/m(Cl-), m(Cl-)/m(HCO3-), m(Cl-)/m(SO42-), m(Ca2+)/m(Na+), m(Ca2+)/m(Mg2+), sodium adsorption ratio (SAR), and m(Cl-) showed that the four parameters of m(Na+)/m(Cl-), m(Ca2+)/ m(Na+), m(Ca2+)/m(Mg2+), and SAR could be used to evaluate seawater intrusion in Hainan province. These results have reference value in the strategic goal for construction of a Hainan "international tourism island" and rational utilization of local groundwater. |
