摘　　要：为提高上海地区室内观赏植物的多样性,采用层次分析法(AHP),从观花性状、观株性状、生长性状3个方面12个评价指标对上海辰山植物园展览温室内引种栽培的21种闭鞘姜属植物进行观赏价值综合评价。结果表明,开花率、花期、叶色叶质在综合评价中的总权重占比均超过0.1,为影响闭鞘姜属观赏价值的主要因子;根据综合评分结果,将21种闭鞘姜属植物划分为4个等级;非洲公主闭鞘姜、菠萝椰子宝塔姜、红闭鞘姜、紫色激情长蕊闭鞘姜属Ⅰ级,综合优势明显,适合在上海地区室内栽培应用。Ⅱ级包括穗花闭鞘姜等9种,具有一定的推广应用价值,可以结合约束层评价等级和应用地环境情况合理开发利用。The research aimed to improve the diversity of indoor ornamental plants in Shanghai by using the Analytic Hierarchy Process(AHP)to evaluate the ornamental value of 21 species of Costus introduced and cultivated in the exhibition greenhouse of Shanghai Chenshan Botanical Garden.The evaluation system included 12 evaluation indexes across three aspects:flowering traits,appearance traits and growth traits.The results indicated that blooming rate,flowering period,leaf color and leaf texture,each accounting for over 0.1 of the total weight in the comprehensive evaluation,were the main factors affecting the ornamental value of Costus.Based on the comprehensive scoring,the 21 Costus species were classified into four distinct grades.Species such as Costus fissiligulatus,C.hybrid'Pina Colada',C.woodsonii,and C.pulverulentus'Purple Passion'were categorized as first-class,possessing significant overall advantages and suitability for indoor cultivation in Shanghai.The second-class encompasses nine species,including C.spicatus,which hold potential for promotion and application and can be developed and utilized strategically,considering the evaluation criteria and the environmental conditions of the application sites.
