【摘要】 通过对呼伦贝尔地区常见的园林绿化乔木进行实地调查，选取外观形态、枝叶、花、果实和生态适应性5个目标层因素，20个标准层评价因素，建立园林绿化乔木观赏性综合评价模型。利用层次分析法(AHP)进行园林乔木观赏性综合评价。结果表明：(1)评价模型中各约束层对目标层的权重大小排序为花>果实>外观特性>枝叶>生态适应性；(2)20个标准层评价因素中，花色、冠形、果色、开花时间和盛花期天数的影响最大；(3)筛选出的观赏性综合评价Ⅰ级(Y>3.5)的树种有5种，包括红宝石海棠、王族海棠、西府海棠、火炬树和花楸。更多还原

【Abstract】 Through the field investigation of common landscape trees in Hulunbuir. Five target layer factors-appearance, branches and leaves, flowers, fruits and ecological adaptability, and 20 standard layer evaluation factors were selected to establish a comprehensive evaluation model of ornamental landscape trees. The comprehensive ornamental evaluation of landscape trees was carried out by using Analytic Hierarchy Process(AHP). The results showed that:(1)The order of weight of each constraint layer to the target layer in the evaluation model was flower>fruit>appearance>branches and leaves>ecological adaptability.(2) Among the 20 standard layer evaluation factors, flower color, canopy shape, fruit color, flowering time and full blooming days varied greatly.(3)There were 5 species selected for grade I(Y>3.5) for comprehensive ornamental evaluation, which were Sorbus pohuashanensis, Malus micromalus cv. Ruby, Malus ‘Royalty’, Malus micromalus, Rhus typhina.更多还原
