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;②20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。
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:①The order of weight of each constraint layer to the target layer in the evaluation model was flower>fruit>appearance>branches and leaves>ecological adaptability.②Among the 20 standard layer evaluation factors,flower color,canopy shape,fruit color,flowering time and full blooming days varied greatly.③There 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.
