[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.
