摘要
利用珠江水系若干有代表性的水化学监测站 1959~ 1984年的主要离子监测数据 ,绘制了河水主要离子三角组分图 .结果显示 :东江主要受硅酸盐与铝硅酸盐岩石溶解作用的控制 .北江上游支流受硅酸盐与铝硅酸盐岩石溶解作用的控制 ,其它支流受碳酸岩溶解作用的控制 .西江各主要支流主要受碳酸岩溶解作用的控制 ,部分支流如柳江中上游、桂江等受硅酸盐与铝硅酸盐岩石溶解作用的控制 .
Based on water quality monitoring data from Water Year Book, portions of the ternary diagram for anions and cations are made in this work. The conclusions are as follows:① The chemical composition of the Dongjiang River is mainly controlled by silicate rock dissolution.② The chemical composition of the upper reach of the Beijiang River is controlled by silicate rock dissolution. The chemical composition of the middle and lower reach of the Beijiang River is mainly controlled by carbonate rock dissolution.③ The chemical composition on most tributaries of the Xijiang River is mainly controlled by carbonate rock dissolution. But the chemical composition of the upper and middle reach of the Liujiang River and the Guijiang River of the Xijiang River System is controlled by silicate rock dissolution.
