Heavy metals in reservoir sediments have a potential and concealed hazard influence on the environment. Benthos are sensitive to the quality of water environment. A research was conducted on the distribution characteristic of heavy metals and benthos in sediments of a reservoir used as water source, and discussions were made on the mutual relations between heavy metals and benthos in sediments. Samples were taken from the sediments of Tangpu Reservoir—a water source reservoir—to analyze the contents of heavy metals and the number of species of benthos. The results showed that significant sedimentation of Fe and Mn in the reservoir sediments, long-term enrichment of Cu and Zn and insignificant accumulation of Cr, Cd and Pb in the reservoir area. The distribution characteristic of benthos was decided by water quality of the reservoir, hydrology, the sedimentary environment, etc., showing much less number of species, biological density and biomass in the reservoir area than the upstream area. The contents of heavy metals such as Mn and Cr had great influence on the distribution of benthos.
