摘要
通过2008年8月(雨季)及2009年2月(旱季)对嘉陵江流域河水进行密集采样,分析测定河水中主要阴、阳离子的化学组成,探讨河水水质的季节及空间变化特征。结果表明,嘉陵江河水离子化学组成主要受流域内碳酸盐岩的溶解控制。同时,降雨、流域内梯级电站开发及其他工农业生产生活活动等也是影响河水化学组成的重要因素。
The chemical composition of major anions and cations in Jialilng River basin were determined based on the dense collection of water samples in August 2008（rainy season） and February 2009（dry season）.The space-time variation characteristics of the water quality were discussed.The results indicate that the chemical composition of ions in Jialing River is mainly controlled by the carbonate rock weathering.In addition,the precipitation and the development of cascade hydropower stations as well as other industrial,agricultural and domestic activities are also significant factors for the chemical composition of river water.
