摘要
河流水化学特征可以从一定程度上反映出人类活动对水环境的影响。对西江干流梧州——肇庆段水化学参数分析表明，该段水体中阴离子以HCO-3占优势，阳离子以Ca^2＋为主，其矿化度为256～414mg／L。岩石风化作用成为控制河流离子化学组成主导因素，工农业污染物输入在一定程度上改变了天然河流的离子化学组成，使NO-3、so2-4等呈现富集趋势。
River hydrochemical characteristics may reflect human influence on water environment in a certain degree. The data from Wuzhou -Zhaoqing reach, xijiang river indicates that the chemical ion composition of the river water is characterized by dominance of HC03- and Ca^2＋ And the mineralization is 256-414 mg/L. Hydrochemical characteristics in Wuzhou -Zhaoqing reach are mainly determined by the rock weatherization. Industry pollutants and anthropogenic activities is responsible to ion concentration changes of components in a certain degree. Our data also indicates that the content of NO3- and SOl- accumulated.
