在对阜阳市城市绿化树种抽样调查基础上,就其树种构成、分布度、多样性等进行了分析,结果表明：城市树木树种结构构成单一、多样性相对较差、分布不均、乡土树种应用较弱。在所调查的68种植物中,总体多样性指数为6.10,行道绿地为2.47,公园绿地为8.24。这些数据显示阜阳市城市绿化的基本格局、树种结构与分布均有待于进一步优化,应提高观花、常绿及彩叶等乡土树种的比例,合理配置乔、灌、地被植物,改善绿化树种分布均匀度,加强植被的养护管理。

Based on statistical analysis of sample survey, the paper analyzed the tree species composition, tree distribution, and tree diversity of Fuyang urban greening. The result showed that the composition of urban tree species is single, the diversity is relatively poor, the distribution is uneven, and application of native tree species is weak. 68 plant species were found in the investi-gation. Their index of diversity is 6. 10 in gross, the road-greenbelt is 2. 47 and the park green land is 8. 24. These data indicated that the basic pattern of urban greening, tree species structure and tree species distribution in Fuyang need to be further optimized. It is necessary to enhance the proportion of native tree species, including flowering trees, evergreens and trees with colored leaves. Moreover, reasonable match should be made with arbors, bushes and groundcover plants, the distribution uniformity of greening tree species should be improved, and the maintenance and management of vegetation should be strengthened.
