Wetlands, tidal flats, seaweed beds, and coral reefs are valuable not only as habitats for many species, but also as places where people interact with the sea. Unfortunately, these areas have declined in recent years, so environmental improvement projects to conserve and restore them are being carried out across the world. In this study, we propose a method for quantifying ecosystem services, that is, useful for the proper maintenance and management of artificial tidal flats, a type of environmental improvement project. With this method, a conceptual model of the relationship between each service and related environmental factors in natural and social systems was created, and the relationships between services and environmental factors were clarified. The state of the environmental factors affecting each service was quantified, and the state of those factors was reflected in the evaluation value of the service. As a result, the method can identify which environmental factors need to be improved and if the goal is to increase the value of the targeted tidal flat. The method demonstrates an effective approach in environmental conservation for the restoration and preservation of coastal areas.
湿地、潮滩、海藻床和珊瑚礁不仅作为许多物种的栖息地具有重要价值，而且也是人们与海洋互动的场所。不幸的是，近年来这些区域面积减少，因此世界各地都在开展保护和恢复这些区域的环境改善项目。在本研究中，我们提出了一种量化生态系统服务的方法，该方法对人工潮滩（一种环境改善项目）的合理维护和管理很有用。通过这种方法，建立了自然和社会系统中各项服务与相关环境因素之间关系的概念模型，并阐明了服务与环境因素之间的关系。对影响各项服务的环境因素状态进行了量化，并将这些因素的状态反映在服务的评估值中。结果表明，该方法能够确定哪些环境因素需要改善，以及目标潮滩的价值是否有望提升。该方法为沿海地区的恢复和保护提供了一种有效的环境保护途径。
