The paper deals with the first trial classification of uncovered peat-swamp land in China by using landsat images （MSS. 140-37

imaged on October 4th

1975; MSS. 141-37

imaged on July 14th

1977）. Having processed optically and by computer and visually interpreted the images

the writer proposed a scheme for the classification of images of uncovered peat-swamp land in Ruoergai PLateau

Sichuan Province

then analysed the imagery

geomorphic

vegetational and thickness features as well as their relationships in different peat-swamp lands. Spectrum of ground objects was measured and the classification of images was tested in field.The classification defined relatively accurately the scope of the peat land. Simultaneously

the peat resources are divided in the area.
