| 摘 要： | 为揭示洞穴水地球化学特征的动态变化特征、控制因素及其环境意义，从2015年1月至2015年6月对贵州织金洞洞穴水的水化学指标进行了为期6个月的动态监测，结果表明:①织金洞洞穴水的水化学类型主要为HCO3--Ca2+-Mg2+型水，阴离子中HCO3-占84.5%以上，阳离子中Ca2+、Mg2+为优势离子；②洞穴滴水 EC、Ca2+、 Mg2+、HCO3-、SO42-浓度均大于石灰岩石裂隙水、池水相应的浓度；③洞穴水滴率、滴量、Ca2+、HCO3-以及Ca2+/HCO3-比值对气候有一定的响应，其地球化学指标具有显著的季节效应；④洞穴滴水中的EC与Ca2+离子浓度呈显著线性关系。

| Abstract: | The aim of this work is to reveal the characteristics of dynamic changes of geochemistry and control factors of the cave water and their environmental implications. A dynamic monitoring over a period of 6 months from January 2015 to June 2015 was conducted for the water chemistry index of the Zhijin Cave in Guizhou Province. The results show that the water chemistry of this karst cave water is dominated by HCO3--Ca2+-Mg2+, where anion HCO3- is accounting for 84.5% and Ca2+and Mg2+are the dominant cations. The value of EC and concentrations of Ca2+, Mg2+,HCO3- and SO42- of cave drip water are higher than those of rock fissure water and pool water. The ratios of cave dripping water rate, drop volume, Ca2+, HCO3- and Ca2+/HCO3-have certain responses to climate. Their geochemical constituents have conspicuous seasonal effects. The EC value and Ca2+concentration of the cave dripping water have a notable linear relationship. |
