湖泊沉积物营养盐的赋存形态及其界面过程研究进展

Research Progress on Nutrients Forms and Interface Process from Lake Sediments

湖泊沉积物是氮、磷等营养盐的重要储存库,是水域生态系统物质与能量循环的重要环节,同时亦是上覆水体营养盐的重要来源,对湖泊水体富营养化具有重要的贡献。研究湖泊沉积物营养盐的赋存形态及其界面过程,对掌握氮、磷营养盐在沉积物与水界面的迁移转化规律,以及揭示湖泊富营养化问题的本质具有重要的意义。综述了当前国内外湖泊沉积物氮、磷营养盐的赋存形态及其界面过程的研究现状及其主要研究的发展趋势。

The sediments are the important reservoirs of nitrogen and phosphorus,and the important link of matter and energy cycle in water ecosystems.Sedimentary nutrients play a significant role in the lake eutrophication.Therefore,the study of nutrient existing forms and interface process in the lake sediments were of great significance of understanding the process of the lake eutrophication.The current researches and developing history of nutrients existing forms and interface process in the lake sediments were summarized,and the development tendency was also analyzed in this paper.
