摘要:
在对合肥市城市绿化树种系统调查的基础上,经统计分析得出:合肥市城市绿化乔木树种共174种,其中乡土树种72种,占乔木树种总数的41.38%。72种乡土树种,隶属32科、58属,其中裸子植物6种,被子植物66种,分别占8.33%和91.67%。根据合肥市园林绿化乡土树种应用现状,提出了合肥今后园林绿化必须坚持“以乡土树种为主,外来树种为辅”的原则,大力调整乡土树种与外来树种应用的比例,为合肥创建国家生态园林城市创造条件。

Abstract:
Based on the investigation of native ornamental tree species in Hefei, there are 174 species of ornamental trees, including 72 species of native tree species, which account for 41.38% of the total tree species. This 72 species of native trees belong to 32 families, 58 genera, including six kinds of gymnosperms and 66 kinds of angiosperms which account for 8.33% and 91.67%, respectively. Based on the application status of native ornamental tree species, we propose that the urban greening could adhere to the principle of “mainly based on native trees, and supplemented with exotic species”, vigorously adjust the application proportions of native species and exotic speciesin the future, to change Hefei into a national ecological garden city.
Key words:  urban greening  landscaping  native tree species  arbor tree species  Hefei city
