| Research Abstract |
In this study, we demonstrated the community structure of lotic macroinvetebrate assemblages in hyporheic zone below streambed.Population densities of several common taxa were found to increase in the hyporheic zone when the drying of surface water occurred. Our results suggested that hyporheic zone served as a refugia for invertebrate during drying event and thus hyporheic zone shouldbe a target habitat of lotic ecosystem conservation.
