基于层次分析法的盆栽造型罗汉松品种综合评价与筛选

Comprehensive Evaluation and Selection of Potted Mode lling Podocarpus macrophyllus Based on Analytic Hierarchy Process(AHP)

为筛选出适于中小型盆栽造型应用的罗汉松品种,对宁波市引进的6种罗汉松优新品种(′台湾金钻′、′金丝红′、′四季红′、′小旋风′、′彩玉′、′菊花′)进行性状观测;并运用层次分析法(AHP)构建盆栽造型罗汉松品种的综合评价体系,包括适应性、观赏价值、产业化难易程度3个准则层和10个具体评价因子。结果表明:′小旋风′品种苗高、地径在4个时间点均显著高于其它5个品种;造型表现、观赏性、经营成本的权重值较大,分别为0.4043、0.1348、0.1021,可作为评价筛选适于中小型盆栽造型罗汉松品种的重要指标;综合评价得分最高的为′彩玉′品种,具有一定的推广应用价值。

In order to screen the Podocarpus macrophyllus cultivars suitable for the application of small and medium-sized potted modeling,the characters of six Podocarpus macrophyllus cultivars(′Taiwanjinzuan′,′Jinsihong′,′Sijihong′,′Xiaoxuanfeng′,′Caiyu′and′juhua′)introduced in Ningbo were observed,and an evaluation system consisting of 3 norms and 10 evaluation factors including the adaptability,ornamental value and difficulty of industrialization was established by analytical hierarchy process(AHP)method.The results showed that the seedling height and ground diameter of′xiaoxuanfeng′were significantly higher than those of the other five varieties at four time points.The modeling performance,ornamental and operating cost were 0.4043,0.1348 and 0.1021,respectively,accounting for a large proportion,which were taken as important index for screening the Podocarpus macrophyllus cultivars suitable for the application of small and medium-sized potted modeling.The variety with the highest comprehensive evaluation was′Caiyu′,which had certain value for popularization and application.
