摘要: 根据2009—2011年三都湾大黄鱼网箱养殖区的水质监测资料,对该海域营养盐的变化及分布特征进行了探讨、研究。结果表明:2009-2011年期间,网箱养殖区海域水质超出作为养殖功能区的水质标准的要求;NO3-N占DIN含量的78.08%~88.89%,是该养殖区海域DIN的主要组成部分;PO4-P对养殖区海域浮游植物的繁殖生长将可能起限制作用,是该海域初级生产力的主要潜在限制性营养盐;营养盐(N,P ,Si)含量存在明显的月变化、空间变化及年际差异等特征。

Abstract: Abstract: We monitored the contents of nutrients in Pseudosciaena crocea Net-Cage Culture Area of Sandu Bay during 2009 to 2011, and assessed the distribution and abundance of nutrients preliminarily. The result indicated that the water quality in cultivation zones of Sandu Bay is superior to the water quality standard (Il kind of GB3097-1997 sea water quality standard). NO3-N is the dominated component of DIN in this area, accounted for 78.08%~88.89% of total DIN. PO4-P may be the critical factor in the growth and reproduce process of phytoplankton, and had a vital influence on the primary productivity of this domain. The contents of nutrients (N, P, Si) present distinct variations between months, years and spaces.
