We analyzed effects and problems of the ordinance on land conservation and management of urban green spaces by using GIS, field surveys and interviews with municipal officers, land owners, and a conservation-society leader in Hachioji city. As a result, we found that the ordinance guaranteeing land conservation and management has an effect on ensuring amount of conservation area and a promotion of management in some conservation area. However, we also found that green spaces which should be conservated and tended to vanish are not designated. It shows that the evaluation of green spaces in Hachioji city should be considered in the ordinance and cooperation with citizens on management is required.
