摘要
本文利用三维水动力和盐扩散方程,计算厦门湾九龙江河口区的盐度时空分布,并利用监测调查所得到的盐度与无机氮、活性磷酸盐的经验关系,对厦门九龙江河口区的无机氮、活性磷酸盐的三维时空分布进行计算,对监测站位的计算值和实测值进行的比较和分析,结果说明在潮周变化尺度,物理混合及扩散对无机氮、活性磷酸盐的分布起主要作用.
Based on a 3-D hydrodynamics model and Dispersion Model of salinity, the spacious time distribution of salinity in Jiulongjiang Estuary is computed. With empirical relations of salinity with TRN and labile phosphate obtained from the survey, the spacious time distributions of TRN and labile phosphate are also calculated. By comparison between the calculated and monitoring data at the stations it shows that variations of tidal-scale, mixture and diffusion of physical factors played a major role in the distribution of TRN and labile phosphate.
