摘    要:为了解西藏地区绿化现状,定量分析其园林绿化基本情况,解决绿化中的相关问题,采用“生物五点法”进行了园林植物群落分层调查,首次对西藏各地的园林植物种类和应用现状进行了全面普查,并详细分析了西藏地区园林绿化的现状、特点及问题,提出了相应举措。调查结果表明,(1)西藏地区应用园林植物共计91科207属368种(含品种);(2)乔木层、灌木层、草本层重要值最高的分别为林芝云杉、大叶黄杨、草地早熟禾,其重要值分别为43.050,25.128,45.950;(3)西藏绿化中应用最多的依次为蔷薇科、杨柳科、菊科、豆科、禾本科、松科、木犀科和柏科,分别有53,23,21,20,19,16,14,12种,分别占调查植物的14.40%,6.25%,5.71%,5.43%,5.16%,4.35%,3.80%,3.26%;(3)绿化发展不均衡,园林植物应用地区差异大,园林植物配置单一;(4)园林植物配比不合理。

Abstract:To figure out current landscaping of Tibet, analyze local garden landscaping quantitatively, and solve greening problems, this paper adopted “five point sampling method” for the stratified survey of garden plant communities, investigated species and application of garden plants in Tibet comprehensively, discussed current situation, characteristics and problems of local landscaping, and proposed corresponding measures. According to the investigation, (1) There were 368 applied garden plant species (including varieties) of 207 genera, 91 families. (2) In the tree layer, shrub layer and herb layer, Picea likiangensis var. likiangensis, Buxus megistophylla, Poa pratensis had the highest importance value, i.e., 43.050, 25.128, 45.950; (3) The most applied families in local landscaping were Rosaceae (53), Salicaceae (23), Compositae (21), Leguminosae (20), Gramineae (19), Pinaceae (16), Oleaceae (14), and Cupressaceae (12), accounting for 14.40%, 6.25%, 5.71%, 5.43%, 5.16%, 4.35%, 3.80% and 3.26% of the total, respectively. (3) The total landscaping level was poor and uneven. The application of landscaping plants varied greatly among regions, and the garden application was poor. (4) Proportion of garden landscapes was unreasonable.
Keywords:Tibet area  landscape plants  investigation;important value
