摘　　要：通过综合分析研究得到了7种重金属元素在大蒲河口海域的分布特征,并依据海洋沉积物质量标准对各种重金属元素的质量等级进行了评价。结果表明:大蒲河口海域沉积物中各种重金属元素的分布特征存在一定的相似性;调查区大部分区域重金属元素的污染程度属于清洁、较清洁级或允许级,只有元素铅(Pb)存在较小范围的轻污染。Through comprehensive research analysis, it was found that the pollution characteristics of seven heavy metals and evaluate the polluted standard based on marine sediment quality stand-ards. The results showed that the distribution characteristics of heavy metals were similar in the survey area. The polluted standard of heavy metals in most areas of the survey area was clean gr-ade or permissible grade and only the polluted standard of plumbum was mild pollution grade in a small area.
