基于AHP法的润楠属树种观赏性评价

Ornamental Value Assessment of 11 Tree Species from Machilus Based on AHP Method

为了从润楠属植物筛选出具有较好景观价值的优良树种并建立润楠属植物观赏价值的评价体系,利用AHP法建立评价模型,从花、叶、果及其他4方面选择了春色叶颜色、树形等10个指标对11种华南地区常见的润楠属植物进行评价。结果表明,各树种的观赏性综合得分区间为4.3395~2.6370,11种润楠属植物可分为3个等级:刨花润楠、广东润楠、黄心树为Ⅰ级,浙江润楠、短序润楠、绒毛润楠、黄绒润楠、柳叶润楠为Ⅱ级,粗壮润楠、木姜润楠、龙眼润楠为Ⅲ级。

In order to screen out the excellent tree species with good landscape value and establish the evaluation system of the ornamental value of the genus Prunus,the AHP method was used to establish the evaluation model,and the color of the spring leaves was selected from flowers,leaves,fruits and other four aspects.10 indicators such as tree shape were used to evaluate 11 species of genus of South China.The results showed that the ornamental comprehensive score range of each tree species was 4.3395~2.6370,and 11 species of Runneraceae could be divided into 3 grades:Machilus pauhoi Kanehira,Machilus kwangtungensis Yang,Machilus gamblei King ex Hook.f.as Grade Ⅰ,Machilus chekiangensis S.Lee,Machilus breviflora(Benth.) Hemsl.Machilus velutina Champ.ex Benth.,Machilus grijsii Hance,Machilus salicina Hance is Grade Ⅱ,Machilus robusta W.W.Smith,Machilus litseifolia S.Lee,Machilus oculodracontis Chun are Grade Ⅲ.
