英文摘要	This study investigates the changing laws of species composition, community composition and species diversity of typical shrubs in southeastern Tibet. It selects 12 typical shrub communities distributed in the five counties of Bayi District, Gongbujiangda County, Milin County, Lang County, and Bomi County in Nyingchi City as the research objects to systematically study characteristics and diversity of main shrub communities in southeastern Tibet. The results showed that the shrubs in Nyingchi of southeastern Tibet have diverse herb plants, while bush is relatively simple. Among the 12 shrub communities investigated, there are 230 species of plants, belonging to 49 families and 107 genera. According to statistics, there are more drought-tolerant families of Compositae, Rosaceae, Leguminosae, and Polygonaceae. Compositae accounted for the highest proportion of 13.1% among the surveyed plants, while Solanaceae, Crassulaceae, and Bignoniaceae only accounted for the smallest proportion of 0.5%. On the whole, D diversity index of the surveyed shrub community varied between 0.74 similar to 0.98, while H diversity index varied between 1.85 similar to 2.96. Different habitat conditions lead to different interlayer structures in community diversity. Except for Sabina pingii, Rhododendron nyingchiense + Rhododendron nivale, Sophora moorcroftiana + Leptodermis forrestii, Quercus aquifolioides, herb layer in the other shrub communities has greater species diversity than the shrub layer.
