The investigations were carried out at 6 tidal flats located on the eastern part of the Seto Inland Sea, Japan. This study was focused on physical characteristics of sediments, namely as particle size of sediment and difference in elevation, and generalizes the relationship between sediments and macrobenthos. A total of 192 species were collected at 187 stations at 6 tidal flats. Physical characteristics of sediment were classified into 9 groups by cluster analysis in relation to sediment particle size and difference in elevation. Those groups had also significant difference in physical characteristics of sediments, and were characterized by some specific macrobenthos species. Distribution of macrobenthos can be explained by the classification of physical characteristics of sediment. These findings show the possibility to predict the variety of macrobenthos community using the physical characteristics of sediment.
调查在日本濑户内海东部的6个潮滩进行。本研究聚焦于沉积物的物理特征，即沉积物的粒径和高程差异，并归纳了沉积物与大型底栖动物之间的关系。在6个潮滩的187个站点共采集到192个物种。通过聚类分析，根据沉积物粒径和高程差异，将沉积物的物理特征分为9组。这些组在沉积物物理特征上也存在显著差异，并以某些特定的大型底栖动物物种为特征。大型底栖动物的分布可以通过沉积物物理特征的分类来解释。这些发现表明，利用沉积物的物理特征预测大型底栖动物群落多样性是有可能的。
