摘要
为探明大亚湾海域生态环境现状,于2011年10月(秋季)、2012年4月(春季)和8月(夏季)在海域布设12个站点,开展了3个航次的水质调查,重点研究了N、P营养盐的分布规律及主要影响因素。结果表明,大亚湾海域无机氮浓度的季节变化为秋季最高,夏季最低;无机磷浓度的季节变化为秋季最高,春季最低。二者的平面分布整体上均呈现由近海岸向远岸逐渐递减的趋势,且梯度分布明显。潮流、浮游植物和人类活动是影响大亚湾N、P营养盐分布的主要因素。
Water quality investigation was carried out in the Daya Bay to explore the current situation of the eco- logical environment in October 2011, April and August 2012. Based on the data collected from 12 stations, the distribution features of Nitrogen and Phosphorus, as well as the impacting factors in Daya Bay were researched. The results indicate that seasonal change of inorganic nitrogen in spring is the highest and in autumn the lowest; seasonal change of inorganic phosphorus in autumn is the highest and in spring the lowest. The plane distribution of DIP and DIN decreases from coastal area to open sea gradually. Current, phytoplankton and human activities are the main factors affecting the distribution of N and P in Daya bay.
