Abstract
To investigate the influence of changes in physical environments, including waves and currents, on the ecosystem of rosky shores, ecological research was conducted at three points on rocky shores, each of which had diifferent wave conditions. It was found that differences in sea urchin popurlation and seaweed volume corresponded to differences in wave conditions at each point. The diversity of phytal fauna at each point corresponded to differences in the volume of seaweed.
