采用野外采样和室内分析，试验结果表明底泥重金属Pb，Cr在不同养殖水体中有显著性差异（P〈0．05）。不同养殖水体底泥中Pb，Cd，As，Cu协同作用明显，底泥中cr在流动水体中容易发生生化反应，在稻田养殖系统中明显促进其它重金属的增加。Pb和As在池塘、稻田、溪河底泥中积累行为有一致性，Cr变化较大。底泥中重金属污染程度属于无污染到中等污染。

The paper investigates characteristics of heavy metal in aquaculture sediments, samples analysis results in- dicate that Pb and Cr levels vary significantly in different aquaculture sediment （P~0. 05）. Cooperating action effects of Pb, Cd, As ture sediment to have and Cu appear to be remarkable in different aquaculture sediment. It is easy for Cr in aquacul biochemistry reaction in flow water, while Cr may accelerate other heavy metals＇ addition in paddyfield. Accumulation of Pb and As appears to be consistent in aquaculture sediment of pool, paddyfield and brook, however accumulation for Cr proves to he changeable . In sum, contamination for heavy metals registers range from pollution-free to moderate pollution in aquaculture sediment.
