Abstract

As the assessment for the project of coastal regeneration, we have tried to expand HSI model (Habitat Suitability Index model) to the HSI model that is available for benthos group of class level. Inthis study, we determined the suitability ranges of IL, ratio of silt, and depth using the former model of HSI for each benthos such as ruditapes philippinarum and batillaria multiformis, and the HSI model was verified as the model for benthos group of class level such as groups of polychaeta, gastropoda, bivalvia using field data in Ago Bay. Further HU (Habitat Unit) of field study in Ago bay was calculated by these models. The result shows that the model may be a tool of general index for the project of coastal regeneration.
