Abstract: Jinshajiang River Basin of Yunnan Province is characterized by complex topography and physiognomy. In accordance with the differences on physiognomy and climate system, the forest vegetation types of this region could be divided into three zones, namely mountaingorge region in the western part, semimountain gorge and central Yunnan plateau in central part, and semimountain gorge in the eastern part respectively. There are different forest vegetation types in different zones; on the contrary, any kind of typical forest vegetation type is an indicator for a specific zone. On the basis of investigation and analysis, the types and characteristics of forest vegetation in mountaingorge region in the western part, semimountain gorge and central Yunnan plateau in central part, and semimountain gorge in the eastern part of Jinshajiang River Basin in Yunnan Province were elaborated, which was very important for the practice of revegetation in this area.Scientific division of vegetation types is an especially important measure to ensure the effect of revegetation, and is also a key factor to make sure that the revegetation is implemented conforming to the natural law. Besides, the paper also illustrated the different forest vegetation types and the differences of them in vertical distribution of the studied three zones in Jinshajiang River Basin, and illuminated the climax communities and subclimax communities of different zones in the watershed. This study provided foundation for revegetation practices, which were in compliance with the theory of closetonature forestry in Jinshajiang River Basin of Yunnan Province.

Key words: Jinshajiang River River Basin, forest vegetation types, distribution pattern
