摘　　要：2014—2016年对平阳西湾海域表层水质进行了连续监测,调查站位点6个,运用富营养指数法、有机污染综合指数法和潜在性富营养化评价法,对平阳西湾海域水质营养状况进行分析和评价。结果表明:海域表层水体无机氮(DIN)、无机磷(DIP)均劣于四类海水水质标准,海域有机污染严重,富营养化程度较高;从空间上看,平阳西湾海区表层海水DIN、DIP、E值、A值的平面分布呈由入海口向远海逐渐递减的趋势。Continuous field data were got at 6 sites during 2014 -2016 in Pingyang west bay. The standard of sea water quality of this bay by ap-plying the eutrophication index method, the organic pollution index method and potential eutrophication assessment model were analyzed. The re-sults showed that the concentration of DIN,DIP in the surface sea water exceeded standards of grade IV sea water quality, the investigated sea re-gion were in serious organic pollution and high eutrophication. Horizontal distributions of DIN and DIP concentration, as well as E and A value, in surface seawater of PINGYANG west bay decreased from estuary toward open sea.
