基于AHP的玉簪品种适应性分析与评价

摘要

以引进的17个玉簪品种为试材,研究其在山东烟台的环境适应性、物候表现及景观特性.运用层次分析法(AHP)对其应用价值进行综合评价.结果表明:不同玉簪品种在烟台的生长表现不一,生长势、分蘖能力和抗逆性是其适应性的重要指标.叶色及生物量大小是影响其观赏价值的主要因子.根据AHP评价结果,将17个引种玉簪划分为4个等级:Ⅰ级包括夏香等4个品种,生长表现强健,观赏性状优良,适合在烟台地区进行栽培和园林应用;Ⅱ级包括大富豪等5个品种,具有一定的应用推广价值;Ⅲ级为圆皱叶等6个品种,适应性与观赏价值综合评定中等;Ⅳ级为金鹰、小黄金叶2个品种,在烟台地区综合应用价值最低,不适合进行大规模园林应用.%The adaptability,phenological observation and landscape characteristics of 17 Hosta species introduced to Yantai region were evaluated based on analytic hierarchy process(AHP).The results showed that adaptability differed between different species,growth potential,tillering ability and stress resistance were important indexes to adaptability.The color of leaf,biomass were the major factors affecting the ornamental value of Hosta species.According to the evaluation result,17 Hosta species were classified into 4 grades.The 4 species such as H.plantaginea ''Summer Fragrance'' were in grade Ⅰ which had best adaptability and highest ornamental value,perfectly suitable to garden application in Yantai.The 5 species such as H.plantaginea ''Big Daddy'' were in grade Ⅱ which had better popularization value.H.plantaginea ''Yuanzhouye'' and other 5 Hosta species were in grade Ⅲ which had certain adaptability and ornamental value.H.plantaginea ''Golden Edger'' and H.plantaginea ''Golden Cadet'' were in grade Ⅳ which obtained lower application value and were not suitable for garden application in large scale in Yantai.
