摘要

摘要: 针对哈素海富营养化日趋严重的现实，系统开展了湖泊沉积物中不同形态氮及有机质的空间分布和污染特征研究。结果表明，表层沉积物中TN、OrgN、NH+4N及有机质的水平分布均表现经向分异特征，OrgN的分布特征主导了TN的水平分布格局，有机质与TN具有强相关性。沉积柱芯中TN随深度增加而递减，有机质和OrgN与TN的垂向分布相似，尽管 NH+4N的垂直变化分异较大，但仍表现于表层富集的特点。OrgN为表层沉积物和沉积柱芯中氮的主导形态，NH+4N为无机氮的主导形态，成岩过程中，沉积物中TN只有极少部分在发生矿化。沉积物中有机质主要来源于湖中芦苇等大型挺水植物及陆源输入。哈素海表层沉积物的氮污染对底栖生物已经产生了严重的生态毒性效应，对底栖生物群落及整个水生生态系统构成了严重威胁。

Abstract: Hasuhai Lake is one of the representative shallow lakes in grassland areas of China, and its eutrophication is becoming more serious. The study on the character of spatial distribution and pollution of the nitrogen forms and organic matter revealed that the content of the total nitrogen (TN), the organic nitrogen (OrgN), the ammonium nitrogen and the organic matter in the surface sediment of the lake had an obvious differentiation in longitudinal direction. The distribution characteristics of TN in surface sediments were mainly dominated by the distribution characteristics of OrgN, and TN had a significant correlation with organic matter content. In the sediment cores, the TN content and the organic nitrogen content both had the same trend that their content decreases with the increasing depth. The vertical distribution of ammonium nitrogen in the sediment core was various, but it was also enriched in the surface sediments. The organic nitrogen is the main exiting form of nitrogen in surface sediments and sediment core, and ammonium nitrogen is the main exiting form of inorganic nitrogen. There was very little TN mineralized in the diagenesis. The typical sources of organic matter in surface sediment of Hasuhai Lake may be macrophytes such as reed and terrestrial source. The pollution of nitrogen in the surface sediments of Hasuhai Lake has serious biology toxicity effect on the bottom biology communities and aquatic ecosystem.
