Abstract: In the course of vegetation mapping of large-scale and medium-scale, the thermal, multispectral, color-infrared and panchromatic aerial photo-graphs may be used. We have undertaken the aerial remote sensing experiment in Tengchong area Yunnan Province. Based upon the different combination of the marks of interpretation directly and indirectly, one may interpret the vegetation types. The synthetical method to conduct the interpretation of remote-sensing imagery can give rather reasonable results. This paper shows the following marks of direct interpretation, namely, the colors and tones of imagery of plant community and its veined construction, the shape, size and height of plant community, stand, or individual plant and their projective shape. The marks of indirect interpretation include the altitudinal, latitudinal, geomorphologic position and the characteristics of parent rocks where the plants grow. The indirect mark also consists of the degree of human activity influencing the distribution of vegetation. To engage the automatic vegetation classification, intensive interpretative marks of each vegetation types may be shown in the key. This paper gives a key to interpret the vegetation types in the evergreen broad-leaf forest area in Tengchong area of Yunnan Province, by using panchromatic aerial photographs with the scale 1:35000, and the scale 1:34000 color-infrared.
