Geographically, it lies on the transitional zone from the Nanling mountain range to Southeast hills, and to the Dongting-Jianghan plain, and from the Yunnan- Quichou plateau to the Southeast hills. Owing to the transitional features of zonal and geographic location in Hunan, a seris of changes in the features of landform, and soil occur, and that lead to the diyersified differentiation in ve- getational features between the southern part and the northern part, as well as between the eastern part and the western part in Hunan.
