摘要
文章重点研究了长江涪陵段的磷(总磷和总溶解性磷)在不同水期、不同断面的分布规律.研究表明,不同水期长江总磷显现的特征总体为枯水期和平水期明显高于丰水期;长江水质中总磷以总溶解性磷为主;受乌江水质影响,在混合段存在水质的分层现象,并提出了混合段的长度;同时,长江涪陵段的泥沙沉降也不明显.
Distribution characteristics of phosphorous （including total phosphorus and total dissolved phosphorus） in Fuling sector of the Changjiang River in different seasons were studied in this article. The result showed that total phosphorus in dry and normal rainy seasons was higher than that in flood seasons. Total dissolved phosphorus was the main component. Under the influence of the Wujiang River, stratification can be observed in outpouring sections in the Changjiang River. The length of outpouring section was also estimated. Sediment sinking was not obvious in Fuling sector of the Changjiang River.
