Fig.2 Land Use Change Pattern (1984 - 1989)
4.2 land Use Mixture
The join index is one of the methods how to explain about
the land use mixture. The mixture matrix of land use is
explained using what kinds of land use items connect to
some concerned mesh and how many meshes they are.
Table-1 shows the mixture matrix of land use at sub-test
site A in '89. This mixture matrix of land use is used as the
context index.
4.3 Land Use Continuity
This land use continuity is calculated by how many pixels
some concerned land use is connected to the same land use
in horizontal and perpendicular directions. This index is
used for express the land use aggregation.
Table-2 shows the continuity for each land use in sub-test
site A.
S.Land Use Change Analysis
It is possible to discuss about land use trend using the
result of land use change analysis. Here land use change in
the term from '84 to '89, was detected.

Fig.2 shows detailed land use change pattern in test site.
The development and unoccupied area were proved to be
mainly derived from the forest and agricultural area. On the
other hand, the development and unoccupied area were
mainly changed to the unoccupied, residential and public
utilities area.
6.Conclusion
As the results of this study, land use ratio was proved to be
used effectively for the regional land use trend
investigation for an existing and new urbanized area. The
estimation of land use pattern was recognized to be
possible using land use mixture and continuity indices.
The land use ratio, mixture and continuity indices were
also possible to apply to the classification of target area
urbanization. The development pattern and its transition
were estimated through multi-temporal analysis.
