本文的目的是评估的投入产出模型对两个基本原则的可持续发展战略的综合海岸带管理（ICZM）和后正常科学的可能贡献。根据这些原则，决策支持工具应该提供一个整体的视角，并处理高度的不确定性。实现可持续性方面的困难部分是由于普遍使用非整体性的“窄系统边界”工具。因此，它们未能抓住重要的生态系统服务，忽视了它们之间的相互依存关系。为了遵守基本原则，我们的方法允许环境资产在多个单元中进行评估，并整合了自然科学中最近的研究成果。这两项工作都能涵盖生态系统服务之间的相互依存关系。因此，我们扩大投入产出模型从两个传统的生态系统服务汇和供应最重要的：支持服务。对塞纳河河口的一项应用涉及海洋运输基础设施对商业鱼类育苗生境的影响。所涵盖的生态系统服务包括生命支持和资源供应。我们的研究结果表明，在2004年至2015年期间，总共73.7平方公里的苗圃面积的恢复将导致在2015年的唯一的股票，超过了“一切照旧”的情况下的44.2%（不确定性范围：35.9%-69.9%）。尽管恢复成本很高，但对宏观经济的负面影响很小。然而，在部门一级，托儿所和三个经济部门之间出现了权衡。在我们的模型中，这种权衡的量化对公众参与决策特别有用。
The aim of this paper is to assess the possible contribution of an input–output model towards two of the basic principles of the sustainability strategy of integrated coastal zone management (ICZM) and Post-Normal Science. According to these principles, decision-support tools should offer a holistic perspective and handle high uncertainty. The difficulties in reaching sustainability are due partly to the prevailing use of “narrow-system-boundary” tools that are non-holistic. Consequently, they fail to capture important ecosystem services and ignore interdependencies between them. To comply with the basic principles, our method allows environmental assets to be evaluated in multiple units and integrates results from recent researches in natural sciences. Both enable coverage of interdependencies between ecosystem services. Thereby, we enlarge input–output modelling from the two conventional ecosystem services of sink and provisioning to the most vital ones: the supporting services. An application to the Seine estuary addresses the impacts of maritime transportation infrastructures on nursery habitats for commercial fish. The ecosystem services covered are life support and resource provisioning. Our results show that the restoration of a total of 73.7 km2of nursery areas over the period 2004–2015 would result in a stock of sole in 2015 that exceeds the “business as usual” scenario by 44.2% (uncertainty range: 35.9%–69.9%). In spite of high restoration costs, the negative macro-economic impact is very low. However, on the sector level, a trade-off results between nurseries and three economic sectors. The quantification of such trade-offs in our model is particularly useful to public participation in decision-making.
