借鉴湖泊底泥的研究方法，对淮河淮南段4个断面的底泥的粒径分布和营养盐氮的水平和垂直方向上的分布进行测定．结果表明：在自西向东的流向上，底泥的粒径在同一深度上由粗变细，纵向上也由粗变细，局部出现异常．不同断面上，上覆水、间隙水和表层底泥的NH4^＋-N和NO3^--N的含量存在较大的差异，沿河流流向分布呈不规则状态起伏，NO3^--N的分布是表层底泥〉上覆水〉间隙水；表层底泥、间隙水中NH4^＋-N浓度均显著高于上覆水，意味着底泥有向上覆水释放NH4^＋-N的动力学优势，柱状底泥的NH4^＋-N的含量总体呈现出姚家湾〉石头埠〉峡山口〉胡大涧的趋势，除峡山口外，NH4^＋-N含量随着深度增加逐渐上升，NO3^--N含量相当．柱状底泥中氮的含量与粒径之间整体趋势上表现为底泥的颗粒越细，对氮的吸附能力越强．

The main purposes of this paper are to investigate the horizontal and vertical distributions of the particle size distribution and nutrient nitrogen in the sediments of four sections of the Huainan segments of the Huaihe river referenced for the research methods of the lake sediment. The results show that the flow in from the west to the east, the distribution features of the particle size in the sediment at the same depth and vertical are on the from coarse to thinner with the local anomalies. The content of NH4^＋ - N and NO3^- - N in the overlying water, interstitial water and surface sediment of different sections is great different horizontally. The distribution of NO3^- - N by large to small order is the surface sediment, overlying water, interstitial water. NH4^＋ -N have deep movement with the dynamics of upward trend from the sediment to overlying water, because the concentrations of NH4^＋ - N in surface sediment and interstitial water were significantly higher than overlying water. The content of NH4^＋ -N in columnar sediment presented by large overall to small trend： Yaojiawan, Shitoubu, Xiashankou and Hudajian. The content of NH4^＋ - N rose steadily with depth, while the content of NO3^- - N showed little change with sediment burial depth. The adsorption ability of nitrogen is stronger with the finer particles of columnar sediment.
