摘要
根据天津近岸赤潮监控区2003年度到2005年度的海洋环境监测资料,利用目前较为通用的富营养化综合指数法对该海域进行了富营养化评价,结果表明:(1)该区域富营养化现状整体呈现逐步恶化的现状,由2003年度的仅有一个站位发生轻微富营养化迅速恶化到2004年度、2005年度的严重富营养化;海水水质已经由2003年度的二类海水,锐减到2005年度的四类海水水质。(2)该区域严重富营养化现状主要是由陆源高营养盐(D IN和D IP)输入造成的。
In this paper, the red-tide monitoring area in Tianjin coastal area was selected as the major research object. Based on the analysis of the large quantity of monitoring materials from 2003 to 2005, the assessment of eutrophication status in this area was done. The results shown that （ 1 ） the eutrophication status in this area presents a quickly deteriorative trend from the tiny eutrophication only at oue station in 2003 to the serious eutrophication status in all of the areas in 2004 and 2005. The water quality is rapidly deteriorating from the second degree of the national water quality standard in 2003 to the fourth degree in 2005. （2） The serious eutrophication status is caused mainly by high DIN and DIP from the terrigenous nutrients pollutants.
