石油泄漏可能是沿海环境最具破坏性的因素之一。漏油事件发生的频率及其造成的有害环境、文化和社会经济影响表明，迫切需要管理和预防工具，以有效解决此类情况。在世界范围内，特别是在过去十年中，大量项目涉及在漏油事件范围内评估沿海敏感性。由于穿越葡萄牙专属经济区和领土沃茨的商业船只往来频繁，加上其气候和地理特征，葡萄牙海岸线极有可能受到石油泄漏的影响。其脆弱性既与葡萄牙沿海地区的密集人类利用有关，也与重要自然价值的存在有关。尽管有这些方面，葡萄牙没有在发生重大石油泄漏时可使用的决策支持工具。目前工作的主要目标是确定最好的沿海敏感性评估方法，葡萄牙，在石油泄漏事件的范围。两种不同的方法进行了比较：敏感性地图和基于算法的敏感性模型。这些方法在葡萄牙的情况下使用的发展过程和潜力进行了审议和讨论。虽然这两种方法都可用于评估沿海敏感性和相应的保护优先事项，但敏感性地图的可行性和有效性已得到证明，使它们具有业务优势。
Oil spills can be one of the most damaging agents for coastal environments. The frequency at which oil spills have occurred, together with the hazardous environmental, cultural and socioeconomic impacts they cause, demonstrate the crucial need of management and prevention tools for the efficient resolution of such situations. Worldwide, especially during the last decade, a large number of projects have dealt with the assessment of coastal sensitivity in the scope of an oil spill event. The Portuguese coastline is highly at risk of being impacted by an oil spill due to the intense commercial vessel traffic that crosses the Portuguese Exclusive Economic Zone and Territorial Waters, and to its climatic and physiographic features. Its vulnerability relates both to the intense human use of the Portuguese coastal areas, and to the presence of important natural values. Despite these aspects, Portugal does not have a decision support tool that can be used in the event of a major oil spill. The main objective of the present work is to identify the best coastal sensitivity assessment approach for Portugal, in the scope of an oil spill event. Two different methods are compared: sensitivity maps and algorithm based sensitivity models. The development process and potential for use of these approaches in the Portuguese situation are considered and discussed. Although both approaches are viable to assess coastal sensitivity and the corresponding protection priorities, the proven feasibility and effectiveness of sensitivity maps grant them an operational advantage.
