摘要

摘要: 通过对夏季珠江口区域沉积物间隙水营养盐剖面分析,调查了营养盐含量分布和特征,探讨了有机物的降解特性、营养盐的底部通量估算和作用.结果表明,珠江口沉积物间隙水中营养盐以高含量铵盐为主要的存在形式,沉积物中有机物的降解反应主要在厌氧状态下进行,底部水体铵盐的增加来源于底部沉积物有机质的降解释放,而且对水体的营养盐循环有较大的贡献.

Abstract: The profile of nutrient salts in interstitial water of sediment are analyzed in the Zhujiang Estuary (Pearl River Estuary) in the summer of 1999,and based on the profiles of content and characteristic of nutrients,the relationship between nutrients in interstitial water and organic matter decomposition in sediment is discussed.The results show that ammonium with high content is the main existence form of nutrients in interstitial water of sediment,and organic matter decomposition is completed in anaerobic condition.The increase of ammonium content in bottom water results from the decomposition of organic matter and release of metabolic production,and bottom ammonium flux is an important resource for nutrients geochemistry in the Zhujiang Estuary.
