摘　　要：本研究很据2021年8月天津大港滨海湿地生态系统附近海域6个站位的监测数据,分别采用单因子指数法、多项水质参数综合指数法、有机污染指数评价法和富营养化指数法对该海域水质进行了评价;采用Shannon-Wiener多样性指数(H')、Pielou种类均匀度指数(J)、优势度(Y)和丰度(d)等对该海域大型底栖生物进行了评价。水质评价结果表明,无机氮为该海域主要超标因子,其他各项监测因子均满足该海域海洋功能区划要求;大型底栖生物评价结果表明,调查海域大型底栖生物多样性指数处于中等水平。Based on the monitoring data of six stations in the sea area near the coastal wetland ecosystem of Dagang, Tianjin in August 2021, the water quality of the sea area was evalu-ated by using the single factor index method, the comprehensive index method of multiple water quality parameters, the organic pollution index evaluation method and the eutrophication index method;the Shannon-Wiener diversity index (H'), Pielou evenness index (J), dominance index (Y) and abundance index (d) were used to evaluate the macrobenthos in the sea area. The water quality evaluation results showed that inorganic nitrogen was the main over-standard factor in the sea area, and other monitoring factors met the requirements of marine functional zoning in the sea area. The macrobenthos evaluation results showed that the macrobenthos diversity index in the investigated sea area was at a medium level.
