Marine macrophytes (macroalgae and angiosperms) were defined as one of the biological quality elements to assess the ecological quality status of transitional and coastal waters by the European Water Framework Directive (WFD, 2000/60/EC). In the present study, the Ecological Evaluation Index (EEI-c) was tested to assess the anthropogenic impact by using marine benthic macrophytes (macroalgae and angiosperms) and pressures by using MA-LUSI in the Turkish marine waters. Macrophyte samples were collected from 56 stations on the coasts of Turkey (at 17 Black Sea, 15 Marmara Sea, 13 Aegean Sea and 11 Mediterranean coastal water bodies) in the summer period between 2014 and 2016. In total, 209 marine macrophytes (macroalgae and angiosperms) taxa were found in all stations. The study revealed high ecological status class for 15 sites, good for 21 sites, moderate for 6 sites, poor for 10 sites, and bad for 4 sites. The MA-LUSI index was tested from the Corine land cover map which affects 1.5 km buffer zone around the sampling sites. The relationship between the pressure index MA-LUSI and EEI-ceqr (eqr: ecological quality ratio) was also tested, and a negative linear relationship was found between MA-LUSI and EEI-ceqr in the Turkish sites. The present study supports the use of the EEI-c index for ecological quality state classification in a wide area of Turkish coastal waters.

欧洲水框架指令（WFD，2000/60 / EC）将海洋大型植物（宏藻和被子植物）定义为评估过渡和沿海水域生态质量状况的生物质量要素之一。在本研究中，对生态评估指数（EEI-c）进行了测试，以评估通过使用海洋底栖植物（宏藻和被子植物）对人为的影响以及通过使用MA-LUSI在土耳其海洋水域产生的压力。在2014年至2016年夏季，从土耳其海岸的56个站点（分别在黑海17个，马尔马拉海15个，爱琴海13个和地中海沿岸的11个水域）的56个站点采集了大型植物样本。总共有209个海洋大型植物（大型藻类和所有站均发现被子植物类群。研究发现15个地点的生态状况等级很高，21个地点的状况良好，6个站点适中，10个站点较差，4个站点较差。MA-LUSI指数是通过Corine土地覆盖图测试的，该图影响了采样点周围1.5 km的缓冲区。压力指数MA-LUSI与EEI-c之间的关系还测试了eqr（eqr：生态质量比），并且在土耳其站点中MA-LUSI和EEI-c eqr之间存在负线性关系。本研究支持将EEI-c指数用于土耳其沿海水域的生态质量状态分类。
