Floristic Characteristics of Vascular Plants in Dry Valleys of the Upstream of Jinsha River
In order to understand the floristic characteristics of the dry valleys in the upstream of Jinsha River, methods of consulting literature material with field investigation and specimen colletion were used, and the results showed that: (1) There were 111 vascular plant species belonging to 95 generas in 51 families, and families and generas with single species were predominate. (2) The floristic composition is dominated by the temperate elements.The endemism was rich, 60 species endemic to China, 4 species to the upstream of Jinsha River.The flora was widely related to other areas, such as African, Tethys area, and the arid valleys of the other great rivers.The flora was transitional trend of tropical composition to temperate composition. (3) The study indicated that this area had a tendency toward semi-desertification, and the environment was fragile.
