摘要
本文在比较四种计算通量方法的基础上 ,根据珠江八大口门的径潮实际情况 ,选取“潮时入海通量计算方法 1”和“潮时入海通量计算方法2”探讨珠江总汞、铜、铅、镉等重金属的入海通量计算 .并分别计算了溶解态通量与颗粒态通量 .采用“水位———水位———流量”图解法以对部分未知流量进行测算 ,是对河口地区和海洋污染防治研究的一种尝试 .
On the basic of comparing four types of the tlux calculating method,“tide-time calculating method 1 of the flux into the sea”and method 2 are choosed to discuss the flux of heavy metals(Hg、Cu、Pb、Cd)into the sea,with the consideration for the actul status of the Pearl River.The flux of the dissolving form and that of the grain form are also counted in the paper.Adopting“Water levelwater level-flux”chart resolving method to count some unknown flux-data is an attempt at the study of pollution contro1&prevention of the bayon and sea.
