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

在该项目期间，研究了以下两个术语。1）为了证明对红树林水域环境进行定量评估的必要性，并根据已经研究了几项研究结果，从物理角度看出，这是从物理角度看出的。此外，还需要进行数量分析以评估环境。2）要量化形成自然红树林环境的机制。由于基本知识需要在红树林地区进行环境评估的基本知识，因此以下机制和过程进行了定量的分析。尤其是红树林沼泽中的潮汐量表，尤其是由红树林/道具根部与潮汐隆之间的相互作用引起的涡流粘度的机制：物理，化学和生物学过程以及它们之间的相互作用，这些过程导致溶解氧气的波动在红树林中很大的范围内溶解的氧气，这对人脉的生态学影响了，从而影响了生态学的生态学，这，这是对生态学的影响。
