Abstract: Some viewpoints which are different from principles of division of the vegeation altitude belts, that has appearred in a large number of literatures, especially from principles of division of those belts, used in the Transverse Mountain area (River Gorge Ceuntry), are presented in this paper: 1) Evidently, it is insufficient to make a division of zones only under the consideration of the principle of three-dimensions and placor, regardless of the historical factor of the vegetation. The authors are of the opinion that the plant life-form eomplexes which are able to show both the space and the time should be the principle of division of zone. 2) The zonal vegetations in the Transverse Mountain chains are represented by the altitude belt structures of vegetation of the mountain-plateau, which is similar to and overleap that af their altitude belt structures in the various mountains. 3) The altiiude belts of vegetation shauld be held to base their genera(ion on the proeess of the natural history aa'cuts. There are eorrelations both in the ecologieal gradients and tile biolegieal oncs among those belts and there is no sueeession anyhow among those belts. 4) Although arid vegetation of dry and hot river valley lies in basal belts, these are some relicts rather than the normal basal belts and the real vegetation of it's kind lnsy appear in those evergreen forests where local faro:able conditions to their development exist.
