| 摘 要： | 表层岩溶泉是储存于表层岩溶带的地下水,为近地面的表层地下水系统,它的普遍分布是西南岩溶峰丛区居民聚集和繁衍的重要条件。本文选取重庆市南川区典型的岩溶峰丛区6个较有代表性的表层岩溶常流泉点,分析表层岩溶泉水化学特征。研究发现：①6个泉点泉水化学类型以HCO3.SO4-Ca型为主,其次为HCO3.SO4-Ca.Mg型,个别为HCO3-Ca型;②常规水化学指标中,受人类活动的影响,各泉点泉水HCO3-含量较高,SO42-和NO3-含量偏高。③各泉点微量金属元素除As和Ba未达地下水质量标准GB/T 14848-1993Ⅰ类水体标准,其余测试指标均符合Ⅰ类水体标准。

| Abstract: | The Karst Spring is stored as groundwater in the surface karst zone and is belong to the surface groundwater system in the around ground. Its distributed situation is the crucial condition for collecting and living of the resident in the westsouth Karst area. The article chooses 6 representitive points this area and analyzes the chemical characters of the surface karst spring water. The result shows 1） the chemical type of the Spring water gives priority to HCO3 · SO4- Ca. , secondly HCO3·SO4- Ca · Mg, specific HCO3-- Ca. 2） For the chemical index of the general water, the content of the HCO3, SO4 2-and NO3- is on the high side, 3） Besides As and Ba, the other minim element keep to the water substance standard of GB/T 14848--1993 I. |
