Hefei Round-the-City Park has typical urban forest characteristics. This paper uses vegetation ecology methods to analyze the community structure of the park, and species composition, tree-height distribution and DBH (diameter at breast height) were described. There are 27,662 trees in the study area, which has an urban forest area of 42.5 hm². The average DBH was 19.2 cm, stand density was 651 trees·hm² and average basal area was 20.8 m²·hm^-2. Based on a health assessment, the trees in the park are in generally good health, as the healthy trees in the urban forest in the park accounted for 53.4 % of the total number. Through calculation of tree growth index and association correlation of component species in the park, the community structures were analyzed. The results show that community structures in the park are complex; there are 22 pairs of species with positive association and individuals in the following communities grow well and are more stable, including mainly Platycladus orientalis-Prunus cerasifera f., atropurpurea-Osmanthus fragrans, Robinia pseudoacacia-Ligustrum lucidum, R. pseudoacacia-Ginkgo biloba-Photinia serrulata, Populus canadensis-L. lucidum-O. fragrans, Sophora japonica-L. lucidum-Buxus sinica, Cyclobalanopsis glauca-Distylium racemosum.
