Abstract:
The typical landscape avenue of Nanjing was taken as the research object，the aerial photography，field survey and GIS technology of the drone were used to obtain the road green space information and established the database.Combining ecological theory，quantitatively evaluated the plant landscape characteristics of road greenbelts，and proposed optimization strategies for the shortcomings of the configuration model.In order to complete the evaluation of the current situation of road greening in Nanjing and the improvement of the theory of plant landscape design.The results showed that the plants in the green belt of Nanjing city were native，the distribution of plants was significant.Plant configuration patterns were diverse and adapted to local conditions.The landscape was distinctive，because of the introduction of garden aesthetics and ecological design concepts.But there were still some problems.Single plant species were planted in old town，new and excellent plant varieties were less used，plant community were unstable in some sections，in order to create good landscapes in the short term，the plant growth law was considered poor.Based on these observations，when the urban road landscapes would be adjusted in the future，local dominant species and native plant can be used as main greening materials，and properly combined with new varieties.The construction of natural plant communities，the integration of ecological design ideas and garden aesthetics should be emphasized.Unique urban roads of ecological landscape will be built by introducing nature.These will be the direction of urban roads green space construction and development.
