抄録

<p>We analyzed habitat characteristics of mussels as ecological indicator species of river ecosystem using river national census on river environment. The results indicated: (1)mussels are suitable for indicator species to lower sections in large river. (2)Mussels are suitable for the indicator species of the sections where width between the levees is wide and river regime coefficient is large. (3)In order to inhabit mussels, the sections have to have flood plains where total area of back water is more than 8000m2, flood frequency is a few times per a year, friction velocity is more than 0.05m/s.</p>
