Abstract:: In order to investigate heavy metal pollution and its potential ecological risk in sediments of watershed in Beijing, 84 test sample sites were set up in Yongding River Basin, Chaobai River Basin, Wenyu River Basin, Juma River Basin and Ju River Basin. Sediment samples have been collected to measure the contents of copper (Cu), zine (Zn), Chromium (Cr), cadmium (Cd), nicked (Ni) and arsenic (As) of sediment by analysis methods of ICP-MS and BCR continuous extraction, distribution characteristics of heavy metals and the change of nutrient were analyzed. At the same time, potenstial ecological harm index and cumulative index method were used to compresively evaluate the ecological risk of heavy metals in sediment of river basin. It turned out that with soil quality standard of Beijing for the value of ratio, sediment eutrophication of middle and lower reaches was serious in rivers of Beijing, heavy metal enrichment strength decreased in the order: Cd > (Cr, As, Zn) > (Cu, Ni). As the sediment potential ecological risk assessment of heavy metals, extent of injury decreased in the order: Cd > (Cr, As, Zn) > (Cu, Ni), the potential ecological risk of downstream was the biggest, the biggest ecological risk was found tin Juma River. According to pollution assessment by method of cumulative index, the pollution degree of rivers in Beijing decreased in the order: downstream > middle > lower reaches, the largest pollution of heavy metal was Cd in sediment, followed by Cr, As and zinc, less polluting was Cu and Ni. To sum up, pollution degree of rivers in Beijing decreased in the order: Juma River > Yongding River > Chaobai River > Wenyu River > Ju River. Especially, the accumulation of heavy metals of downstream in sediment was more, and had the largest potential ecological risk.
