| 英文摘要 | Aims As a unique geographical unit of the earth, the Tibetan Plateau is extensively covered by various Stipa communities. However, their vegetation features have not been reported systematically till now, especially in some scantily explored regions. In this study, we endeavor to reveal the community types, quantitative characteristics and climatic distribution patterns of Stipa steppes in these areas based on primary releves obtained from fieldwork. Methods We collected a total of 223 plots in 79 study sites in the Changthang Plateau and the Yarlung Zangbo Valley, ranging from 79 degrees E to 91 degrees E. The categories of Stipa formations were identified according to the classification scheme in Vegetation of China and then verified by Nonmetric Multidimensional Scaling. We performed detrended correspondence analysis and detrended canonical correspondence analysis to hunt for the alteration of Stipa communities along the precipitation gradient. Quantitative characteristics including species richness, coverage, biomass as well as importance values (IV) of dominant species were calculated and visualized, respectively. Important Findings Stipa steppes in scantily explored regions of the Tibetan Plateau are classified into 11 formations but major formations are rather limited in number. Formation (form.) Stipa purpurea is the most widespread Stipa assemblages not only in scantily explored regions but also across the whole Tibetan Plateau. The characteristics of Stipa communities, including coverage, species richness, productivity and IV of dominant species, demonstrate the features of typical alpine steppes on the Tibetan Plateau. Precipitation proves to be the prime climatic factor controlling the distribution patterns of Stipa assemblages. Form. Stipa subsessiliflora var. basiplumosa and form. Stipa glareosa normally distribute in arid habitats, but rainfall for the former is of greater variance. Form. Stipa roborowskyi and form. Stipa capillacea favor moderately moist environment. Form. Stipa purpurea and form. Stipa roborowskyi can tolerate a fairly broad range of precipitation. |
