TOPSIS及模糊综合评价法在植物观赏性评价中的应用——以刨花润楠为例

Application of TOPSIS and Fuzzy Comprehensive Evaluation Method in the Ornamental Evaluation of Plants——Taking Machilus paunoi Kanenira for Example

为筛选出更优的园林绿化材料,探索园林绿化树种观赏特性的科学评价方法,以刨花润楠为例,根据8位林业专家给出的刨花润楠的9项观赏指标的重要性序列值,采用Delphi法对各观赏指标进行赋权,在此基础上运用TOPSIS法及模糊综合评价法对梅州地区初选出的25株野生刨花润楠进行观赏性综合评价,并将2种方法评价结果进行综合。最终,25株刨花润楠被评为4个等级,并用方差分析对所分等级进行检验,检验结果显示所分4个等级之间存在显著性差异,表明综合2种方法的评价结果是有效、可行的。评价选出的优良单株可为园林绿化利用提供材料。

In order to select a better garden greening materials, the scientific evaluation methods of ornamental characteristics of landscape tree species was explord in this article,taking Machilus paunoi Kanenira for example. According to the importance of the sequence of values of Machilus paunoi Kanenira 9 ornamental indicators given by the 8 forestry experts, The Delphi method was used to empower the ornamental index. Based on the weights determined by Delphi method,the TOPSIS method and fuzzy comprehensive evaluation method were used to the ornamental characteristics comprehensive evaluation of 25 wild Machilus paunoi Kaneniras, which primarily selected in Meizhou area. The evaluation results were combined with the two methods. Eventually,25 strains were divided into 4 grades, and the grade was tested by variance analysis. The results showed that there were significant differences between the 4 grades. Therefore,The final results showed that the combination of the two methods were effective and feasiblee. The excellent indi- vidual plant selected by evaluation can provide reference for using landscaping materials.
