Abstract
Because the Open-space conservation activities need to be continued, this research aimed to clarify the process and the possibility that the inhabitants in the suburban-area want to participate in the Open-space conservation activities. The inhabitants develop relations with Open-space in the process of five stages; already-known, experience, use in daily life, and evaluation and participation hope to civic action. As for the Open-space use, the possibility of developing is high when there is Open-space from the residence area within 1,000m. And If an Open-space scale is 10ha or more, it becomes more positive than participation in the Open-space conservation activity. Moreover, it became difficult to do an Open-space evaluation when Open-space of 1ha or more was one place within 1,000m from the residence area. And I was suggested the possibility that relations with Open-space and inhabitants do not develop.
