The sediment is a important component of the water body. Geoaccumulation index and the potential ecological risk of heavy metals in sediment of Baiyangdian Lake were evaluated and compared with the historical data, the causes of pollution were analyzed. The contents of Cd, Pb were very high in sediment of Baiyangdian Lake, and there existed extremely stronger ecological risk for Cd and slight-medium ecological risk for Pb. The pollution in upper reaches was more serious than that in lower reaches. In the places where the village was intensive and populous, the water quality was broken heavily with very high content of heavy metal, and breeding fish very densely and raising more duck and crab aggravated the pollution. The degree of pollution in sediment of 0-10 cm in Baiyangdian Lake was greater than that of 10-20 cm. The sediment was polluted and still aggravated at the bottom in recent years. Among 21 sampling sites, Anxin bridge, the South Liu Village, original Tangriver sewage storehouse and Tong kou were polluted comparatively serious than other places. Based on these results, the administration measure for Baiyangdian Lake was put forward.
