| 摘 要： | 为了研究淮河干流水体和沉积物中总磷(TP)、沉积物中重金属的沿程分布规律和时空变化特征，于2014—2017年采集淮河干流(正阳关—洪泽湖)19个断面的水样和沉积物样品，分析各采样时段干流各断面水样和沉积物中TP、沉积物中重金属砷(As)、铜(Cu)、铅(Pb)、锌(Zn)、镉(Cd)等污染物的浓度和分布，探讨河道流量、温度等因素对水体及沉积物中TP、重金属时空分布的影响。结果表明:水体、沉积物中TP和沉积物中重金属浓度汛前大于汛后；水体中各形态磷浓度汛中沿程分布较汛前、汛后更均匀；流量、温度是影响TP和重金属分布的主要原因。

| Abstract: | The distribution as well as the spatial and temporal variation of total phosphorus(TP)in the water and sediment, and the heavy metals in the sediment in the main stream of Huaihe River were studied. Samples of water and sediments in 19 sections of the main stream of Huaihe River from the Zhengyangguan to the Hongze Lake were collected from 2014 to 2017. The TP in the water and sediment, and heavy metals(As, Cu, Pb, Zn, and Cd)in the sediment were analyzed to investigate the concentration and distribution along the river. The effects of the flow rate and temperature on the spatial and temporal distribution of the TP in water and sediment, and heavy metals in the sediment were also discussed. The results showed that the concentration of the TP and heavy metals during pre-flood season is more than that after flood season, and the distribution of various forms phosphorus in water during flood season is more uniform. The flow rate and temperature are main influencing factors for this distribution of TP and heavy metals. |
