基于层次分析法的8种槭属植物观赏价值综合评价

Comprehensive Evaluation on Ornamental Value of 8 Acer Species Based on AHP Method

【目的】为槭属(Acer)植物的园林景观应用提供科学依据。【方法】以8种河南乡土槭属(Acer)植物为试验材料,运用层次分析法(AHP),选取13个指标构建槭属植物观赏价值综合评价体系,并对8种槭属植物进行观赏价值综合评价。【结果】13个评价指标中,叶色、呈彩期和翅果的总排序权重值最高,是影响槭属植物观赏价值最重要的指标;8种槭属植物中,综合评价Ⅰ级的是血皮槭(A.griseum)和鸡爪槭(A.palmatum),Ⅱ级是三角槭(A.buergerianum)、元宝槭(A.truncatum)、地锦槭(A.mono)和茶条槭(A.ginnala),Ⅲ级是青楷槭(A.tegmentosum)和飞蛾槭(A.oblongum)。【结论】血皮槭(A.griseum)和鸡爪槭(A.palmatum)的观赏价值高,生态适应性强,具有良好园林应用价值。

【Objective】The objective of the paper is to provide the scientific basis for the application of Acer species in garden landscaping.【Method】Eight native Acer species in Henan are selected as tested materials.The comprehensive evaluation system of ornamental value in Acer species is established by selecting 13 indexes based on AHP method,and then the comprehensive evaluation of ornamental value in eight Acer species is conducted.【Result】Leaf color,color duration and samara total rank have gained the maximum weight in 13 evaluation indexes,which is the most important indexes affecting ornamental value of Acer species.Among eight Acer species,A.griseum and A.palmatum belong to levelⅠ,A.buergerianum,A.truncatum,A.mono and A.ginnala belong to levelⅡ,and A.tegmentosum and A.oblongum belong to levelⅢ.【Conclusion】A.griseum and A.palmatum have excellent ornamental value and strong ecological adaptability,which have better landscape application value.
