摘要
于2003年8月28日对奥运帆船赛场海域海水水质要素进行了现场调查,并以无机态氮(DIN)、无机态磷(PO4-P)、化学耗氧量(COD)、溶解氧(DO)为化学指标参数,探讨了该海域的富营养化状况。结果表明,奥运会帆船赛场海域除石油烃外,大部分海域符合国家一类海水水质标准,石油烃平均含量超过国家二类水质标准。该海域调查海区PO4-P、DIN主要受陆源排放影响,特别是浮山湾至石老人沿岸海域含量较高。部分区域已经开始呈现轻微富营养化状态,富营养化状况主要受陆源排放等因素的影响。整体上奥运会帆船赛场海域水质良好,污染较轻。
A cruise of survey in the 2008 Olympics boat-sailing field and adjacent area was carried out on Aug. 28th, 2003. Preliminarily analysis of the eutrophication status was made at the base of the content of dissolved inorganic nitrogen （DIN）, dissolved inorganic phosphate （PO4-P）, dissolved oxygen（DO） and chemical oxygen demand （COD） as well. The results showed that in most of the survey area, the water quality was in accordance with 1st Class for the National Seawater Standard except petroleum hydrocarbon. The average concentration of petroleum hydrocarbon was beyond 2nd class of the National Seawater Standard. The contents of PO4-P and DIN were mainly influenced by the runoff from lands, with a comparatively higher concentration in the coastal areas from Fushan Bay to Shilaoren bathing beach. The distribution of EI unfolded that part of the survey area were in a status of slightly eutrophication. The eutrophication was mostly influenced by the land runoff and related factors. The sea water quality of the Olympic boat-sailing field was good and just slightly polluted on the whole.
