| 摘 要： | 以2010年8月湘江干流株洲段代表性断面水质与底泥监测资料以及其他资料为基础,采用WASP7模型模拟该江段丰水期镉浓度,并进行镉污染负荷测算与分配。研究结果表明,WASP7模型较好地重现了镉浓度的变化规律,8月份该河段上游镉入流量2 446.33 kg,下游出流量3 076.44 kg,区间增量630.12 kg,其中点源负荷量241.67 kg,占38.4%,面源负荷量304.49 kg,占48.3%,内源负荷量为83.96 kg,占13.3%。

| Abstract: | Based on the water quality and sediment monitoring data of the representative cross-section of Xiangjiang River in Zhuzhou district in August 2010 and other material,the Cd concentration of the section was simulated by using WASP 7 model and Cd pollution load was calculated and allocated.The results showed that Cd concentration variation was reproduced by WASP 7 model.In August the upstream river cadmium inflow was 2 446.33 kg,and a flow downstream was 3 076.44 kg,with a range increment of 630.12 kg,of which point source load 241.67 kg,accounting for 38.4%,non-point source load 304.49 kg,accounting for 48.3%,endogenous load of 83.96 kg,accounting for 13.3%. |
