We review approaches and tools currently used in Nordic countries (Denmark, Finland, Norway and Sweden) for integrated assessment of 'ecological status' sensu the EU Water Framework Directive as well as assessment of 'eutrophication status' in coastal and marine waters. Integration principles for combining indicators within biological quality elements (BQEs) and combining BQEs into a final-integrated assessment are discussed. Specific focus has been put on combining different types of information into indices, since several methods are currently employed. As a consequence of the variety of methods used, comparisons across both BQEs and water categories (river, lakes and coastal waters) can be difficult. Based on our analyses, we conclude that some principles and methods for integration can be critical and that a harmonised approach should be developed. Further, we conclude that the integration principles applied within BQEs are critical and in need of harmonisation if we want a better understanding of potential transition in ecological status between surface water types, e.g. when riverine water enters a downstream lake or coastal water body.
我们回顾了北欧国家（丹麦、芬兰、挪威和瑞典）目前用于按照欧盟水框架指令综合评估“生态状况”以及评估沿海和海洋水域“富营养化状况”的方法和工具。讨论了在生物质量要素（BQE）内组合指标以及将BQE组合成最终综合评估的整合原则。由于目前采用了多种方法，因此特别关注将不同类型的信息组合成指数。由于使用的方法多种多样，跨BQE和水类别（河流、湖泊和沿海水域）进行比较可能会很困难。基于我们的分析，我们得出结论，一些整合原则和方法可能至关重要，应制定统一的方法。此外，我们得出结论，如果我们希望更好地了解地表水类型之间生态状况的潜在转变，例如当河水进入下游湖泊或沿海水体时，在BQE内应用的整合原则至关重要且需要统一。
