摘　　要：[Objective] The aim was to screen out excellent Aceraceae germplasm resources which can be applied in gardens and urban landscape. [Method] The set of 17 biological traits of 24 Aceraceae species were observed and recorded. Taking into consideration aesthetic evaluation of different groups of people, the studied species were graded in quantitative scale. The species with higher overall score is considered better germplasm resource. [Result] The Aceraceae species with top ten highest overall scores were： Acer japonicum ＇Aconitifolium＇ （45.5）, Acer palmatum var. thunbergii （43.8）, Acer palmatum （41.8）, Acer elegantulum （39.2）, Acer elegantulum var. macrurum （39.2）, Acer rubrum （39.1）, Acer Cordatum（38.8）, Acer truncatum （38.3）, Acer olivaceum （37.7） and Acer acutum （37.3）. [Conclusion] The above ten species can be used preferentially as excellent Aceraceae germplasm resources for landscaping.[目的]选择24个槭树科植物在杭州植物园内进行试验,评价出优劣程度,为槭树科植物在园林和城市景观中的应用筛选出优良种质资源。[方法]通过对槭树科植物17个方面的生物学特征观测与记录并参考不同人群的美观度评价,以分值的方式统一量化打分,综合分值越高的越优良。[结果]综合分值最高的前十个槭树科植物为:鹅掌槭(45.5)>小鸡爪槭(43.8)>鸡爪槭(41.8)>秀丽槭(39.2)=长尾秀丽槭(39.2)>北美红枫(39.1)>紫果槭(38.8)>元宝槭(38.3)>橄榄槭(37.7)>锐角槭(37.3)。[结论]鹅掌槭、小鸡爪槭、鸡爪槭、秀丽槭、长尾秀丽槭、北美红枫、紫果槭、元宝槭、橄榄槭和锐角槭,可以优先筛选为园林绿化中的优良种质。
