In the future development of coastal regions, it will be necessary to make efforts conserving the valuable natural coasts and/or creating new appropriate environments in order to keep the ecological systems as natural as possible. The purpose of this study is to clarify the relationship between the environmental changes accompanied by the developmental works and the natural inhabitants for the creation of new environments which and suitable for both human beings and living things.
One of the most important results of our study is a quantitative understanding of the structural changes of ecological communities formed by living things depended on the changes of habitat environments.
We have succeeded in divising a new evaluation method which can express the restoration process of inhabit environments using visual presentation. This method which can express the relationship between changing natural inhabits and the living things in course of time is believed to provide a great deal of important information during the conduction of environmental restoration projects.
