【摘要】 根据2003年8月至2004年8月的调查资料,对广州海域营养盐的质量浓度及分布特征进行了初步探讨。结果表明:无机氮(DIN)、PO43--P和SiO32--Si质量浓度的年平均值分别为1.56,0.047和2.50 mg/L;其平面分布特征均表现为湾顶高于湾外,近岸高于远岸,但其季节变化特征不尽相同。更多还原

【Abstract】 Based on the field investigation data during August,2003 and August,2004 in the Guangzhou sea area,the contents and distribution characteristics of nutrient were discussed.Results showed that the annual average concentrations of DIN,PO^3-₄ P and SiO^2-₃ Si were 1.56,0.047 and 2.50 mg/L,respectively.The contents decreased gradually from inner bay to outer bay,and from nearshore to offshore.There were the different seasonal variations among nutrient in the Guangzhou sea area.更多还原
