摘要(Abstract)：

为了探索日益增强的旅游活动是否会对黄龙水质产生影响,从2010年4月下旬到11月上旬,以泉水中保守离子Sr2+作为示踪剂,采用野外自动监测、水样采集和室内分析相结合的方法,对黄龙风景区溪流水中Sr2+、PO3-4、NO-3等离子质量浓度做了一个旅游季节的监测;结果表明,在补给泉和相应景点间,水中磷酸盐质量浓度变化趋势呈现明显的差异性,且后者比前者均有所升高,其年平均值在5个景点分别升高2.65、1.94、0.91、0.11和1.35倍,而示踪剂Sr2+离子质量浓度变化趋势则正好相反,说明黄龙风景区溪流水磷酸盐浓度已受到不同程度的外源污染;进一步对比分析各景点磷酸盐、硝酸盐质量浓度与同期游客人数间的关系,结果发现两者间变化趋势呈现明显的一致性;为了排除偶然性因素影响,笔者于2011年对水中磷酸盐质量浓度重新做了上述观测,结果与2010年相似;因此可以推断,黄龙景区溪流水中磷酸盐、硝酸盐质量浓度已明显受到过度旅游活动的影响。
