Abstract: | The complexity of the landscape in Japanese metropolitan suburbs is the result of high competition among land-demanding economic activities. Although both urban and rural planning legislation has played certain roles in the ordering of land-use, lack of coordination among different zoning systems is still a key issue in the proper development and conservation of limited land. This study investigated the effects of land-use master plans on actual control of land use through maximal utilization of detailed grid data with advanced GIS functions. We analyzed land-use changes in the Osaka metropolitan area for three periods: 1979–1985; 1985–1991; 1991–1996, and compared these changes with the zoning status in each period. This study demonstrates that disordered developments resulted in an increase of vacant areas in urban fringes, which also accelerated the fragmentation of forests and farmlands, causing a disordered spatial pattern from which it will be difficult to recover with the present land-use master plans. |
