Abstract
Primary purpose of this study is to practically optimize the process through which landscape design will contribute to restoring natural environment in riverside parks in urbanized areas. The following points are identified through the continuous survey and analysis of vegetation and related environment in "Natural Zone" of Ishikawa River Park in Osaka Prefecture for five years of period after 1st stage of park development was completed. A series of phenomena that will take place in and around the environment of the site would be integrated into the process of planning and design of landscape by focusing on differences found in their scale, frequency and endurance.For instance, artificial disturbance of vegetation such as maintenance practice of agricultural irrigation channels would be effective to promote nature restoration if it is taken into account of planning and design in advance.In addition, it would be possible to estimate post development changes and their future trends clearly, and to project the process of nature restoration as well, by planning and design based on scale of time-space in the landscape. All these findings suggest the potential that landscape design would be developed as a practical methodology for nature restoration with long-term practice that integrate design and maintenance of post construction periods.
