The most important objective within the European Water Framework Directive (WFD) is to achieve a 'good ecological status' (GES) for all waters, by 2015. Some methodologies have been developed for assessing GES within natural water bodies, in which the ecological status is a perceived or measured deviation from a reference condition. However, the WFD also consider 'Heavily modified water bodies' (HMWB) (a water body resulted from physical alterations by human activity, which substantially change its hydrogeomorphological character, e.g. a harbour). In implementing the WFD, environmental managers are required to assess the status of HMWBs in terms of achieving 'Good Ecological Potential' (GEP). This contribution defines and studies GEP from an ecological point of view, taking into account some ecological restoration principles. Finally, this contribution gives some guidance on how establish GEP, using as example a harbour within the North East Atlantic.
《欧洲水框架指令》（WFD）最重要的目标是到2015年使所有水体达到“良好生态状态”（GES）。已经开发了一些方法来评估自然水体中的GES，其中生态状态是指与参考条件相比感知到的或测量到的偏差。然而，WFD也考虑“高度人工改造水体”（HMWB）（因人类活动的物理改变而形成的水体，其水文地貌特征发生了重大变化，例如港口）。在实施WFD时，要求环境管理者根据实现“良好生态潜力”（GEP）来评估HMWB的状态。本文从生态学角度定义并研究了GEP，同时考虑了一些生态恢复原则。最后，本文以东北大西洋的一个港口为例，就如何确立GEP提供了一些指导。
