| Outline of Final Research Achievements |
In order to examine the method of estimation of sustainability of green area ecosystem as indicator of naturality, we investigated the relationship between the activities of organic matter production by plants and the activities of organic matter decomposition by soil microbe in natural forests have sustainable nutrition cycle system and define the retalionship as indicator of naturality. We also tried to estimate the naturality of artificial urban forests using the relationship. We compared the relarionships between natural forests and and artificial urban forests. The relationships were clear in natural forests established on gradual slope (less than 20 degree). In artificial urban forests, the relationships were not clear, because the activities of organic matter decomposition were too low for the activities of organic matter production compared with natural forests. Therefore, we estimated that sustainabiity is not established yet in artificial urban forests.
