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

本项目期间，主要进行了以下两个方面的研究：1）说明红树林水域环境定量评价的必要性，并提出评价中存在的问题。根据多项研究结果，任何红树林环境都应进行定量评估，以抑制生态恶化和恢复生态。进一步，提出了环境评估中需要定量分析的一些过程。2）对自然红树林环境形成的机制进行量化。作为红树林地区环境评估所需的基础知识，以下机制通过对日本西表岛、越南东海岸和厄瓜多尔北海岸的观测，对红树林沼泽潮汐尺度的水动力机制，特别是涡粘性引起的机制进行了定量分析。红树林/支柱根与潮汐流的相互作用b：引起红树林地区溶解氧大范围波动，影响红树林生态的物理、化学、生物过程及其相互作用
