| 摘 要： | 为探讨人类活动影响下的垂直气候带岩溶泉水化学变化,以重庆金佛山水房泉和碧潭泉为例,基于两泉自然环境和人类活动强度差异,利用独立样本t检验、Gibbs图解法、主成分分析(PCA)及地球化学敏感性分析等方法,对两泉水文地球化学特征及其控制因素进行对比研究.结果表明,垂直气候带岩溶发育的差异性导致碧潭泉离子总浓度高于水房泉.不同高程的岩性决定了水房泉水化学类型为HCO_3-Ca型,而碧潭泉为HCO_3-Ca·Mg型.碳酸盐岩溶蚀是两泉Ca~(2+)、Mg~(2+)和HCO_3~-的主要来源,水房泉SO_4~(2-)、NO_3~-、PO_4~(3-)、K~+和Na~+在冬夏季受酒店排污影响出现峰值,碧潭泉各指标年内变化平稳.水房泉水属于Ⅳ类水,而碧潭泉水质相对较好. PCA分析表明水-岩作用为两泉的首控因子,酒店排污和来自降水的离子输入分别对水房泉、碧潭泉水质具有重要影响,同时降水导致的水土流失与淋滤效应也对两泉有一定影响.水房泉的地球化学敏感性大于碧潭泉,故应针对不同高程岩溶系统特点制定相应保护措施,特别是要重视景区酒店污水的处理.
