Planning Approach to Land Use Structurization (2)

Analysis of the Land Use Changes

Abstract

There are some approaches to land use plannings, but most of them are discussed from the sides of city and economical plannings. The land use plannings which were organized from the side of natural land potential are few.
Around the urbanized areas, the land use changes from natural to urbanized areas are continuously happening and it's becoming hard to keep the dynamic balances that had been held historically between natural and urbanized land uses.
In this study, the land use changes relate to natural land situations were firstly discussed and the changing processes were analysed as the Markov Chain process in case of Osaka prefecture through mesh date. The decreasing processes of natural land uses and the increasing processes of urbanized land uses are shown in figure 7 and 8. Here the tendency of decreasing processes of natural land uses were analysed relate to the increasing processes of urbanized land uses, but the details could not be analysed because the mesh size (about 500 m × 500 m) was too large and the accuracy of mesh data was not severe enough theoretically.
The mechanism of land use changes were discussed here, but there should be more elements that relate to land use changes and more strict land use controls would be needed to natural land potentials.
