摘要：通过涵盖西藏自治区的阿里、日喀则、拉萨、山南、林芝、昌都和那曲7个地区(市)、涉及33个县的370个西藏灌木林群落标准地调查,从树种组成、盖度、树高结构、直径结构和物种丰富度等方面研究西藏灌木林群落的结构特征。结果表明:(1)主要灌木林群落类型(优势树种组)有白刺花、班公柳、茶藨子、杜鹃、高山栎、高山柳、旱柳、红柳、金露梅、锦鸡儿、狼牙刺、爬地柏、蔷薇、忍冬、沙棘、水柏枝、小檗、绣线菊、栒子、野丁香、紫金标和醉鱼草等灌木林群落;(2)灌木林群落物种组成较为单一,优势树种在群落中所占的比例较大,常常形成单优群落;(3)灌木林群落的盖度多在0.4以上;(4)灌木林群落的树高多分布于0.1～6.0m范围,地径多分布于1～5cm范围。
Based on the inventory of 370 sample plots covering 33 counties which belong to 7 districts（cities）including Ngari,Shigatse,Lhasa,Lhoka,Nyingtri,Chamdo and Nakchu,the structural characteristics of shrub forests in Tibet from aspects of species composition,vegetation coverage,height structure,diameter structure and species richness were analyzed.The results show：（1）The dominate genera or species of main shrub communities are Sophora viciifolia Hance,Salix bangongensis,Ribes sativum,Rhododendron spp.,Quercus semicarpifolia,Salix cupularis,Salix matsudana,Tamarix ramosissima,Potentilla fruticosa,Caragana spp.,Sophora Davidii,Sabina procumbens,Rosa spp.,Lonicera spp.,Hippophae spp.,Myricaria spp.,Berberis spp.,Spiraea spp.,Cotoneaster spp.,Leptodermis spp.,Ceratostigma willmattianum and Buddleja spp..（2）Species composition in shrub communities is simple and is often dominated by single species.（3）The coverage of the shrub communities is larger than 0.4.（4）The tree height of the shrub communities distributes between 0.1 m and 6.0 m,and the ground diameter distributes between 1 cm and 5 cm.
