【Abstract】 To provide information for management and conservation of plant resources on the flood plain of the Niyang River in Tibet and to revise the "Flora of Tibet" ,two surveys in October of 2003 and from May to July of 2004,and floristic analysis were conducted. Results revealed 333 species (including varieties and forms) belonging to 188 genera and 67 families of seed plants. These were also the dominant families of the Pan-tropic flora in China. Floral genera consisted of both temperate elements (83.77%) and tropical ele-ments (16.23%) with temperature being the dominate component. Floral species were also primarily temperate elements (59.94%) and tropical elements (3.47%). The temperate elements were mainly Sino-Himalaya (32.81%) and endemic elements of mainland China (31.55%).更多还原
