红海湾养殖水域营养盐消长与温度、盐度、浮游植物量的关系

Relationship between Nutrients, Temperature, Salinity and Phytoplanktonin the Aquaculture Waters of Honghai Bay

红海湾海水养殖水域的营养盐、盐度、温度、浮游植物和叶绿素的观测结果表明，该水域中氨氮、亚硝酸盐及磷酸盐的消长受水系混合所制约。春季硝酸盐、氨氮和秋季磷酸盐与浮游植物之间存在着负相关，秋季表层叶绿素与营养盐（除氨外）存在着正相关。

By observing nutrients, salinity, temperature, phytoplankton and chlorophyll in the aquaculture waters of Honghai Bay, the result shows that the growth and decline of nitrate, phosphate and ammonia in the waters are dominated by mixing of hydrographic nets. The correlation between nitrate and ammonia in spring, and phosphate and phytoplankton biomass in autumn are in the negative form. The correlation between nutrients (except for ammonia) and surface chlorophyll are positive in autumn and nutrient salinity and bottom chlorophyll shows the negative correlation.
