| 摘 要： | 用乙炔抑制法对北黄海海域沉积物-水界面反硝化速率进行了研究,并用分相浸取法对相应站位沉积物中氮的赋存形态进行了分析.结果表明,该海域界面反硝化速率在3.2.～7.5 μmol/m2·h之间,可提取无机氮的平均含量范围在0.7 2～80.36 μg/g之间.对两者之间的关系研究表明,该海域反硝化速率与沉积物中离子交换态(IEF)硝酸盐氮和可提取无机总氮之间存在较好的相关性,相关系数分别为0.947和0.88 6(P＜0.01);与碳酸盐结合态(CF)和铁锰氧化物态(IMOF)的硝酸盐氮及氨氮之间相关性不明显.

| Abstract: | The acetylene inhibition technique was conducted to evaluate the denitrificaton rate across the sediment-water interface in the North of Yellow Sea and the sequential extraction method was employed to analyze the different forms of nitrogen contained in the sediment of the corresponding stations.The study of their relations was showed that the denitrificaton rate was closely linked with nitrate nitrogen in iron-exchangeable form and extractive inorganic total nitrogen of the sediment in this maritime space ... |
