Abstract

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.
