| 摘 要： | 根据对胶州湾女姑山增养殖海域1998年5月～9月的连续监测资料，参照潜在性富营养化的概念，应用NQI指数对该海域的营养状况进行分析。认为该海域水质富营养化是7月3～8日Skeletonemacostatum和Biddulphiaaurita混合型赤潮形成的基础，磷、硅营养盐的消耗是赤潮消亡的主要原因；赤潮消亡之后浮游植物群落发生演替，水体叶绿素a仍保持较高含量，NQI指数也相应较高，水质表现为磷限制潜在性富营养化，由于磷酸盐的限制没有发展为赤潮。

| Abstract: | In 1998 continuous surveys were conducted in situ to monitor red tide in Nugushan seawater of Jiaozhau Bay, and the red tide caused by Skeletonema costatum and Biddulphia aurita during 7. 3-7. 8 was recorded. Based on the concept of potential eutrophication, the Nutrient Quality Index (NQI) was used to assess the nutritional condition of seawater. The results showed that nutrient-enrichment was the basis of this red tide, silicate and phosphate were two key factors withering away this red tide; From then on, minitype diatom was replaced by larger diatom, the sea area was in the stage of phosphorus-limited potential eutophication and the algal proliferation was restricted, but the condition was easily changed by external complement. |
