Abstract
The vegetation in the suburban forests-usually called as "Satoyama"-is rich and complex. However, the detailed data of the topography for geographical analysis could not be gotten. We could make the detailed topographical data (5m grid DEM) from the aerial photographs taken in 1995, and also restore the vegetations (divided for 9 categories) from the aerial photographs in 1949, 1977 and 1995 over about 6.1km2 in a part of the suburban forest, Kaisho & Hirokute Forest, near Nagoya City, central part of Japan. Interannual change of the vegetation and its considerable reasons could thus be analyzed from the topographical environment. We can get only 323 patterns of the vegetation category change through 3 terms. The 13 main patterns (explained for 47.5% of all) of the category change are selected and almost of these patterns are arrived at category-C (delicious forest). It is suggested that the change patterns have some relationship to the altitude, slope angle and slope direction.
