The developmental activities and utilization of Japanese coastal seas have been increased recently. Consequently, the production of coastal fisheries, especially of those in enclosed seas, are considerably affected by artificial impacts such as reclamation from the sea and increased pollution load. The objective of this paper is to propose a new ecotechnologic method to recover the polluted coastal environment by using an artificial beach system. An artificial beach was constructed in the Matsushima Bay. Following conclusions have been drawn based on the results of the laboratory experiment, field investigation and continuous survey in artificial grave beach system in the Matsushima Bay :(1) The rapid removals of turbidity, suspended solids, phosphorus and ammonium nitrogen by the artificial beach system were simultaneously achieved.(2) The major mechanisms may be explained that the treatment of polluted waters is carried out by physical adsorption and biological filtration through the artificial beach system.(3) The system has much merit such as simplicity of the structure, energy-free operation, and capability to use tidal current cycle effectively, and ease of maintenance. It suggests that restoration of polluted coastal area may be expected by using this artificial beach system in enclosed coastal areas.

近年来，日本近海的开发活动和利用有所增加。因此，沿海渔业的生产，特别是在封闭海域的生产，受到人为影响的很大影响，例如填海和增加污染负荷。本文的目的是提出一种利用人工滩涂系统恢复受污染的海岸环境的新的生态技术方法。在松岛湾建造了一个人工海滩。通过对松岛湾人工坟滩系统的室内实验、野外考察和连续监测，得出以下结论：(1)人工沙滩系统同时实现了对浊度、悬浮物、磷和氨氮的快速去除。(2)人工沙滩系统处理污水的主要机理是通过人工海滩系统进行物理吸附和生物过滤。(3)该系统具有结构简单、无能源运行、能有效利用潮流周期、易于维护等优点。这表明，在封闭的沿海地区，利用该人工沙滩系统可以恢复受污染的海岸地区。
