摘　　要：该试验研究了巢湖和瓦埠湖沉积物中氮的组成和分布特征。结果表明,巢湖、瓦埠湖总氮的平均含量分别为0.533和0.265g/kg,氮的主要组成均为有机氮(94%);有机指数显示,瓦埠湖遭受的有机污染程度低于巢湖。Composition and distribution of nitrogen in Chaohu Lake and Wabu Lake sediments were studied. The results showed that the mean total nitrogen contents in Chaohu Lake and Wabu Lake were 0. 533 and 0.265 g/kg respectively, and the primary composition of nitrogen was organic nitrogen （94%）. The organic index indicated that the organic pollution degree of Wabu Lake was lower than that of Chaohu Lake.
