| 摘 要： | This paper describes a new type of transformed Landsat images (LBV images) and their application in discriminating soil gleization in subtropic region of China,LBV transformaition was worked out by the present author for extracting useful information from original landsat images.Using this method three black and white images,L image ,B image and V image ,were computer generated from original bans of a Landsat scene,which covers a large area of 34 528 km^2 in Hubei and Hunan province in south China.Then a Color composite was produced by these three images .This kind of black-and-white and color images contained rich and definite geographic in formation.By a field work ,the relationship between the colors on the composite and the land use/cover categories on the graound wa established.37 composite colors and 70 ground feature categories an be discriminated altogether,Finally,17 land use/cover categories and 10 subregions suffering from soil gleization were detemined ,and the gleiztion area for the study area was estimated to be 731.3 km^2.
