发生在沉积物-水界面的剧烈生物地球化学作用对沉积物和上覆水体具重要的环境效应，然而此方面研究很少。本文通过云贵高原四个湖泊湖水和孔隙水NH和NO剖面，沉积物柱芯不同结合态氮含量剖面分布，界面扩散通量，影响氮循环的因素及它们季节性变化规律等的对比研究，初步揭示了湖泊沉积物一水界面的氮循环及其环境效应。
The severe biogeochemical interactions that occur at the sediment-water interface have important environmental effects on sediments and overlying water, however, few studies have been done on this area. In this paper, through comparative study of the NH and NO profiles of lake water and pore water, the distribution of nitrogen content in different bound states of sediment cores, the interfacial diffusion flux, the factors affecting the nitrogen cycle and their seasonal variation in four lakes of Yunnan-Guizhou Plateau, Revealed the nitrogen cycle and its environmental effects at the water-lake interface of lake sediments.
