This study quantitatively evaluated Habitat Suitability Index (HSI) and species diversity of benthic invertebrates using a distributed hydro-thermal model and observed benthic samples from 45 localities in the Natori River basin, Northeast of Japan. We applied probability density function and histogram analysis to the Suitability Index (SI) model analysis. To evaluate basin-scaled habitat values of invertebrate families, we used the index Weight Usable Ratio (WUR). From the viewpoint of repeatability in the multiple modeling manners, Diptera had the highest WUR in basin. We estimated spatial distribution of Shannon-Weiner diversity index based on the HSIs to evaluate species diversity throughout the basin. Results in the both applications showed that regions found in the top 80% of the diversity index were allocated from the upper to the middle stream.
