Abstract

. 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 0.74~0.98, while H diversity index varied between 1.85~2.96. Different habitat conditions lead to different interlayer structures in community diversity. Except for Sabina pingii , Rhododendron nyingchiense + Rhododendron nivale , Sophora

西藏东南部主要灌木群落特征及多样性

．研究了藏东南地区典型灌木物种组成、群落组成和物种多样性的变化规律。选取分布在林齐市八一区、贡布江达县、米林县、郎县、波密县5个县的12个典型灌木群落作为研究对象，系统研究了藏东南地区主要灌木群落的特征和多样性。结果表明:藏东南林芝灌丛草本植物种类丰富，灌丛较为单一;在调查的12个灌丛群落中，共有植物230种，隶属于49科107属。据统计，耐旱科较多的有菊科、蔷薇科、豆科、蓼科。菊科在调查植物中所占比例最高，为13.1%，而茄科、天竺葵科和山楂科所占比例最低，仅为0.5%。总体上，调查灌木群落的D多样性指数在0.74~0.98之间，H多样性指数在1.85~2.96之间。不同的生境条件导致群落多样性的层间结构不同。除沙宾、宁华杜鹃花、苦参外

期刊介绍： The Journal publishes original research papers and review articles. Researchers from all countries are invited to publish pure or applied ecological, environmental, biogeographical, zoological, botanical, paleontological, biometrical-biomathematical and quantitative ecological or multidisciplinary agricultural research of international interest on its pages. The focus is on topics such as: -Community, ecosystem and global ecology- Biometrics, theoretical- and quantitative ecology- Multidisciplinary agricultural and environmental research- Sustainable and organic agriculture, natural resource management- Ecological methodology, monitoring and modeling- Biodiversity and ecosystem research, microbiology, botany and zoology- Biostatistics and modeling in epidemiology, public health and veterinary- Earth history, paleontology, extinctions, biogeography, biogeochemistry- Conservation biology, environmental protection- Ecological economics, natural capital and ecosystem services- Climatology, meteorology, climate change, climate-ecology. The Journal publishes theoretical papers as well as application-oriented contributions and practical case studies. There is no bias with regard to taxon or geographical area. Purely descriptive papers (like only taxonomic lists) will not be accepted for publication.
