K-T transformation’s forestry significance is discussed in this paper. The idea of the transformation can be applied to the forestry analysis. On the K-T feature space

the forestry significance is obvious and the forest is of higher greeness

wettness and lower brightness. And it occupies relative fixed place. By this specific property

forest and its environment characteristic can be described with their reflective spectrum.In this paper

remotely semsed estimate model of stand volume is developed with K-T transformation’s features in Linan county

Zhcjiang province. It includes forest and environment characteristic

and is of physical meaning. The model is demonstrated satisfactorily by the experiments. The average estimate precise of stand volume is 90% for the primary stand classes

It can be applied to the South-China mountain.
