A study of the Land-use Changes in the Watershed of the Shinobazu Pond

Abstract

A watershed ecological study of the Shinobazu Pond was performed with special attention to the land-use changes.
The land-use type which was dominant in each mesh (100×100 m) was derived from the topographical maps surveyed in 1880, 1909, 1937 and 1982. The landform classification followed the land-condition map surveyed in 1978.
No correlation was detected between the land-use diversity and the stability in the watershed. The land-use types were associated with the landform types significantly, though the watershed has been located in the suburban or urban area of Tokyo.
