| 摘 要： | 利用2009 年7 月对辽河口水域航次的调查结果, 对该水域营养盐的形态和分布特征进行了探讨,并对其主要控制过程进行了讨论。结果表明： 辽河口水域营养盐的变化范围较大。磷主要以磷酸盐的形式存在, 其余依次是颗粒态磷PP、溶解有机磷DOP, 三者含量相差不大; 氮主要以硝酸盐的形式存在, 其余依次是溶解有机氮DON、颗粒...

The mixing behavior of nutrients in summer at Liaohe Estuary |
| |
| Abstract: | Nutrients and their distributionI at Lihaohe estuary were studied in July 2009. Concentrations of nutrients varied at Liaohe estuary. At Liaohe estuary, phosphate was the predominant species of total phosphorus (TP), followed by particulate phosphorus(PP), and dissolved organic phosphorus(DOP); nitrate was the predominant species of total nitrogen (TN), followed by dissolved organic nitrogen (DON), particulate nitrogen(PN), and nitrite, ammonia. The data indicated that nitrate, nitrite, dissolved organic nitrogen (DON), dissolved inorganic nitrogen(DIN), dissolved total nitrogen(DTN), and total nitrogen(TN) behaved conservatively, while ammonia and particulate nitrogen (PN) did not. Particulate phosphorus (PP), dissolved organic phosphorus(DOP), dissolved total phosphorus(DTP), total phosphorus(TP), and silicate behaved conservatively, mainly controlled by mixing process of salt and fresh water. According to sea water quality standard, all the dissolved inorganic nitrogen fell short of the fourth category of sea water quality, and phosphate just reached or fell short of the fourth category of sea water quality. |
