| 摘 要： | 根据2004-2006年珠江口海域的调查资料,对营养盐含量和比值与浮游植物群落结构的关系进行分析.结果显示,调查海域维持丰富的氮、磷、硅,其中氮、硅以东宝河口最高,磷以深圳湾最高;丰富的氮、磷、硅和较高的N:P均可能是形成调查海域多年来浮游植物群落以硅藻类占优势的主要原因;但是在深圳湾、桂山岛、万山列岛及横琴岛附近海域(主要是4月),营养盐含量及其之间的比例发生变化(深圳湾主要是 N:P,后三个岛屿附近海域主要是Si:N),对浮游植物群落结构变化产生影响;并且近年来珠海高速发展的养殖业造成其海域赤潮的频发.

| Abstract: | According to the data observed in the Pearl River Estuary from 2004 to 2006,the nutrient levels,ratios and their relationship with phytoplankton community structure have been analyzed.The results indicated that there were rich dissolved inorganic nitrogen,orthophosphate and silicate in the Pearl River Estuary.The highest level of dissolved inorganic nitrogen,silicate occurred in the mouth of Dongbao river,so did the orthophosphate in the Shenzhen Bay.Abundant dissolved inorganic nitrogen,orthophosphate,sili... |
