摘要
为了解气候变化和人类活动对柳江流域岩溶地下水质量的影响,本文利用在该流域岩溶地下水污染调查时所取得的数据,分别采用单因子评价法和单因子污染标准指数法对其进行了地下水质量和污染评价。评价结果表明:柳江流域岩溶地下水可直接饮用(Ⅱ~Ⅲ类水)的占82.12%,经适当处理可以饮用(Ⅳ类水)和不能直接饮用(Ⅴ类水)的分别占9.27%和8.61%,流域整体上处于轻度污染,局部地区污染较重。
In order to realize the impact of change climate and human activity to karst groundwater quality in Liujiang River basin.In this paper,the groundwater quality and pollution were evaluated by single factor evaluation method and single factor pollution standard index method,using a large number of data obtained from the investigation of karst groundwater pollution in Liujiang River basin in the southwest of China.The evaluation results show that 82.12%of karst groundwater can be directly consumed(classⅡ-Ⅲwater),and 9.27%and 8.61%of groundwater can be directly consumed(class IV water)and cannot be directly consumed(class V water)after proper treatment,respectively.The basin is slightly polluted as a whole,and local areas are seriously polluted.
