Abstract:

本文选取胶州湾周边5条主要入海河流作为研究对象,于2011秋季和2012年春季,测定了河流中无机营养盐的浓度水平,调查了各河流营养盐的主要来源,分析了营养盐的时空变化及成因,并计算了营养盐的入海通量.结果表明,各流域NO3--N、SiO32--Si、NH4+-N、NO2--N浓度主要表现为秋季较高,PO43--P浓度春季较高.白沙河、洋河流域营养盐主要来源为面源污染;墨水河、李村河流域营养盐主要来源于工业废水和生活污水;大沽河流域营养盐主要来源于农田径流和生活污水.除NH4+-N入海通量为墨水河最高外,其余各项营养盐入海通量均为大沽河最高.DIN、PO43--P、SiO32--Si入海通量分别为373.74×103mol·d-1、7.08×103mol·d-1、73.16×103mol·d-1,NPSi数量比约为53110.
