| 摘 要： | 为摸清拉萨市绿化现状，定量分析其园林绿化基本情况，解决绿化中的相关问题，本研究通过生物五点法进行了园林植物群落分层调查，首次在西藏对各地的园林植物种类和应用现状进行了全面普查，并详细讨论分析了拉萨市园林绿化的现状、特点及问题，提出了相应举措。本次共调查园林植物45科、100属、159种（含品种），结果表明：（1）乔木层、灌木层、草本层重要值最高的分别为紫叶李（Prunus cerasifera f. atropurpurea）、千头柏（Latycladus orientalis cv. sieboldii）、草地早熟禾（Poa pratensis），其重要值分别为49.861、27.756、55.386；（2）乔、灌木层中，应用最多的是蔷薇科（Rosaceae）（共27种），其次是杨柳科（Salicaceae）（共18种），再次是木樨科（Oleacea）、柏科（Cupressaceae）和豆科（Leguminosae），分别为9、8、6种，分别占调查乔、灌木的24.77%、16.51%、8.26%、7.34%、5.50%；（3）园林植物种类不丰富，绿化发展不均衡；（4）园林植物配比不合理，引种植物占比极高，乡土植物占比极低。

| Abstract: | For finding out existing landscape condition in Lhasa, providing quantitative analysis of the landscape base situation and resolving the landscape related problems, the research had surveyed the landscape phytocoenology by biology-five-spots according to layer. The investigation had general surveyed the plant species and application in all parts of Tibet for the first time. In this study, we also analyzed and discussed the current situation, characteristics and problems of Lhasa landscape and put forward corresponding countermeasures. There are 45 families, 100 genera, 159 species (including varieties) in this investigation. The results showed that:(1) The highest importance value of arbor layer, shrub layer, herb layer were Prunus cerasifera f. atropurpurea, Platycladus orientalis cv. sieboldii, Poa pratensis, the important value respectively were 49.861, 27.756, 55.386 respectively. (2) The most application arbor and shrub layer in Lhasa was Rosaceae, the total of 27 species;The second was Salicaceae, the total of 18 species;the third was Oleaceae, the total of 9 species; the forth was Cupressaceae, the total of 8 species; the fifth was Leguminosae, the total of 6 species and they occupied 24.77%, 16.51%, 8.26%, 7.34%, 5.50% respectively in the investigating arbor and shrub plants. (3) The landscape plants in Lhasa were not rich and the planting development was lopsided. (4) The proportion of landscape plants composition was not reasonable, the adventitious plants were too high and the indigenous plants were too low. |
