摘要
利用南麂海域4个站位2006年4月至2007年3月的连续调查资料,研究了该海域氮、磷营养盐的季节变化特征及其影响因素。南麂海域的无机氮主要由硝酸盐构成,平均占有比例77%。氮、磷营养盐的季节性变化显著,并且两者呈现同步的上升或下降的趋势。PO4-P与NO3-N的相关性显著(r=0.665)。NO3-N与水温、pH、盐度等多项因子之间均具有显著的相关性,其中与水温的相关性最为密切(r=0.798)。
Based on the data obtained in the investigation in Nanji Islands Sea Area from April 2006 to March 2007, the seasonal variation of nitrogen and phosphorus nutrients are analyzed in this paper. NO3-N is the main composition of DIN and its annual average percentage of DIN is 77%. PO4-P and DIN have the similar obvious variations. PO4-P and NO3-N have a strong relativity (r=0.665). NO3-N has certain relativity with several environmental factors, such as water temperature, pH, Salinity. NO3-N and water temperature have the strong relativity ( r = 0.798 ).
