通过2006年-2010年N、P、Si数据分析广西钦州湾海域N、P、Si的变化趋势、富营养化状况以及限制因子。分析表明:钦州外湾DIN、DIP、SiO3-Si含量呈波浪形变化并有所下降,钦州外湾2006年-2010年均为贫营养,外湾海水水质良好。茅尾海DIN值含量较高,海域受到N的影响。茅尾海2006年-2010年为轻度～中度富营养。茅尾海属于磷中等限制富营养,磷酸盐仅表现为相对不足,仍然有爆发赤潮的危险。控制茅尾海富营养化的关键在于控制磷的入海量。
Through N, P and Si data from 2006 to 2010, the trend of N, P, Si and eutrophication in Qinzhou Bay of Guangxi were analyzed. The analysis shows that the content of DIN, DIP and SiO3-Si in Qinzhou Bay fluctuates and declines. The Qinzhou Bay from 2006 to 2010 is poorly nutritious, and the water quality of the Bay is good. Mawei high DIN content, the waters affected by N. Mao Weihai 2006 - 2010 for mild to moderate eutrophy. Moutai is a medium-phosphorus limited eutrophication, phosphate is only shown as relatively inadequate, there is still the risk of an outbreak of red tide. The key to controlling maui eutrophication is to control the amount of phosphorus entering the sea.
