中文摘要	为了有效治理拉萨河中下游地区山地植被退化,采用群落学研究手段对拉萨河谷亚高山灌丛草甸群落进行了研究分析。结果表明:该区灌丛草甸群落共有维管束植物67种,隶属于27科48属。地理成分及科属分析表明,该区灌丛草甸群落具有明显的温带性质。生活型和叶的性质分析表明,该区灌丛草甸群落的外貌主要是由落叶全缘单叶矮高位芽植物所决定的。拉萨河谷半干旱区亚高山灌丛草甸群落的总特点是以地面芽、微型叶、单叶、草质叶、全缘叶为特征,反映了青藏高原高山、寒旱的性质。在分析灌丛草甸群落特征的基础上,还对其生态恢复进行了探讨。
英文摘要	Method of community ecology was used in the analysis of subalpine shrub-meadow communities in the semiarid Lhasa Valley to effectively prevent the degeneration of mountainous vegetation. The results showed that there were 67 species of vascular plants in 48 genera and 27 families in the shrub-meadow communities. The analysis of geographical factors and plant families and genera demonstrated that the shrub-meadow communities were temperate clearly. The analysis of both life form and leaf characteristics revealed that the physiognomy of the shrubmeadow communities was mainly affected by the nanophanerophytes with deciduous, simple and entire leaves. The subalpine shrub-meadow communities in the semiarid Lhasa Valley were characterized by the hemicryptophytes, nanophyll,herbaceous, simple leaves and entire leaves; and these communities could grow in the high and frigid mountainous regions in the arid Tibetan Plateau. Based on the characteristics of the shrub-meadow communities, the ecological regeneration was also discussed.
