海湾沉积物中的有机质和氮、磷营养物质丰富与否,直接反映了底质环境的优劣。底质环境的好坏在一定程度上又直接影响生物的生存、发育及种类组成。本文主要论述乳山湾表层沉积物中的氮、磷和有机质的含量分布、变化特征及影响因素,并着重分析了与底栖生物之间的关系。 Bay sediments in the organic matter and nitrogen, phosphorus nutrient rich or not, directly reflects the quality of the sediment environment. The quality of the sediment environment to a certain extent, has a direct impact on biological survival, development and species composition. This paper mainly discusses the content distribution, variation characteristics and influencing factors of nitrogen, phosphorus and organic matter in the surface sediments of Rushan Bay, and emphatically analyzes the relationship with benthic organisms.
