This paper aims to examine how the change in land-use was undertaken in some of the residential-industrial area. The land-use analysis, which compared the features of the target regions, was made on the basis of the existing land-use maps. The analytical results may be summed up by three types of change; a change to a residential area, a change to a semi-industrial area, a change to an industrial area. The results of the observations and analysis indicate that the region had been changed to a residential area was naturally welcomed by residents, while the region that had been changed to an industrial area had to restrict the increase of the number of houses, and the region that had been changed to a semi-industrial area brought about complications. In the meantime, the number of vacant lots increased by all three types of change, which may not benefit the environment. There is another trend observed, i.e., the decrease of factories which would not turn into an increase. Such being the case, there is a need to take into consideration the inevitable formation of vacant lots in planning a change of land-use in region where both the residential use and the industrial use coexist.
