During the period of this project, the following two terms were studied.1) To show the necessity of the quantitative assessment of the environment of mangrove water areas, and to pick up problems for the assessment.It was shown from the physical viewpoint, based on several research results which have been studied, that any mangrove environment should be assessed quantitatively for restraining the ecological deterioration and for recovering the ecology. Further, some processes which need to be quantitatively analyzed in order to assess the environment were picked up.2) To quantify the mechanisms which form the natural mangrove environment.As the fundamental knowledge which needs for the environmental assessment in mangrove areas, the following mechanism and processes were quantitatively analyzed through the observations in Iriomote Island of Japan, an east coast of Vietnam and a north coast of Ecuador.a: The hydrodynamic mechanism with tidal scale in mangrove swamps, particularly, the mechanism of eddy viscosity caused by the interaction between mangrove trees/prop roots and tidal flowsb: The physical, chemical and biological processes and the interactions among them which cause the fluctuation of dissolved oxygen in great range in mangrove areas, which influences on the mangrove ecology

在这个项目期间，研究了以下两个术语。1)阐述了对红树林水域环境进行定量评价的必要性，并提出了评价中存在的问题。从物理角度出发，结合已有的研究成果，提出了对红树林环境进行定量评价，以抑制其生态退化和恢复其生态。此外，还提出了一些需要进行定量分析以评价环境的过程。2)量化形成自然红树林环境的机制。作为红树林环境评价所需的基础知识，本文通过对日本伊洛默特岛、越南东海岸和厄瓜多尔北海岸的观测，定量分析了以下机制和过程。a：红树林沼泽潮汐尺度的水动力机制，特别是红树林树木/支柱根与潮汐流相互作用引起的涡动黏度机制。b：造成红树林地区溶解氧大范围波动的物理、化学和生物过程及其相互作用，影响红树林生态
