Investigation and analysis of the tree species in urban greening of Fuyang city

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 investigation. 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.
