摘　　要：硫酸盐还原菌(SRB)的丰度是金属在海水和海洋沉积物中腐蚀速度的一个重要指标。2006年12月10-13日对渤中海域表层沉积物中SRB的丰度分布进行了调查。检测结果表明,各站表层沉积物SRB的丰度按大小排序为BZ28-2S-CEP-BH2站>BZ28-2S-SPM站>BZ28-2S-CEP-BH1站,SRB的平均丰度为1.02×102个.g-1(湿样)。The abundance of sulface-reducing bacteria （SRB） is an important indicator for the metal corrosion speed in sea water and marine sediment. The surveys of abundance distributions of SRB in surface sediments from the Middle Waters of Bohai Sea were made during December 10 to 13, 2006. It is shown from the survey results that the abundance of SRB in surface sediments at station BZ28-28-2S-CEP-BHZ is greater than that at station BZ.28-2S-SPM, the abundance of SRB at station BZ28-2S-SPM is greater than that at station BZ28-2S-CEP-BHI, and the average abundance of SRB is 1.02× 10^2 ceils · g^-1 （wet sample）.
