The European seas are under anthropogenic pressures impacting the state of water quality, benthic habitats and species. The EU Marine Strategy Framework Directive (MSFD) requires the Member States to assess the impacts of pressures and make a programme of measures leading to good environmental status (GES) by 2020. This study presents a method for assessing the quantity and distribution of anthropogenic impacts on benthic habitats in the Baltic Sea by using spatial data of human pressures and benthic habitats. The southern sub-basins were more extensively impacted than the northern sub-basins. Over the entire sea area, deep sea habitats were more impacted than shallower infralittoral and circalittoral habitats. Sand and coarse sediments were the seabed types relatively most impacted in the Baltic Sea scale. A comparison against tentative thresholds for GES showed that in the sub-basin scale only one third of the habitat types was in GES.
欧洲海域正承受着各种人为压力,这些压力影响着水质、海底生境和物种的状况。欧盟海洋战略框架指令(MSFD)要求成员国评估压力的影响,并制定到 2020 年实现良好环境状况(GES)的措施计划。本研究提出了一种方法,通过使用人类压力和海底生境的空间数据来评估波罗的海海底生境受人为影响的数量和分布。南部次盆地比北部次盆地受到更广泛的影响。在整个海域,深海生境比浅海生境和近岸生境受到更大的影响。在波罗的海范围内,沙质和粗质沉积物是受影响最严重的海底类型。与暂定的 GES 阈值进行比较表明,在次盆地尺度上,只有三分之一的生境类型处于 GES 状态。
