摘要
长江主要溶解物质平均浓度(ppm)为:SiO_(2)6.2;Ca 35.0;Mg 5.5;Na 9.0;K2.2;Cl 20;SO_(4)13.5;HCO_(3)127。在本研究区,主要溶解元素受物理混合控制,与盐度呈线性相关,说明是保守行为。文中还估算了长江主要溶解物质的通量。
The average concentrations(ppm)of major dissolved matter in Changjiang River are:SiO_(2)6.2,Ca 35.0,Mg 5.5,Na 9.0,K 2.2,Cl 20,S0_(4)13.5,HC0_(3)127,among them the most concentrated species are Ca and HC0_(3).In the area studied,major dissolved elements are controlled by the physical mixing because they are linearly related with C1%,which also indicates a behavior of conservation.
