Research On Urban Entrance Green Landscape In Nanjing

As necessary pass road, urban entrance plays an important role in the city. Entrance view is a part of the urban landscape ecosystem; its greening effect directly reflects cultural meaning and spirit feature of the city. This paper takes five urban entrances as the research object, analyzes the current status, evaluates the green landscape, identifies landscape problems and solves them. The main conclusions are as follows:(1) Green space is not fully utilized in 5 entrances, especially pillar greening, fence greening and under flyover greening. With the lack of conservation and management, more plants are dead, dropping fruits and garbage are not cleaned, and road conditions are bad.(2) From an ecological point of view, it took and analyzed 38 plots and found that plant species were quiet few, the importance value of species was large different, and a small number of trees and shrubs were reused, such as Cinnamomum camphor a, Ligustrum lucidum, Prunus cerasifera 'Atropurpurea', Osmanthus fragrans etc, which made the landscape similar seriously. Plant diversity of five entrances green space was also quite different, Plant diversity of Zhongshan Gate and Yangtze River Bridge was better than the other entrance area.(3) It analyzed plants dispostion configuration and summarized 9 configurations. At the same time, from ornamental characteristics and time, it summarized that entrance landscape of Nanjing could be enjoied in all seasons, and we could watch flowers in spring and summer and leaves in autumn and winter.(4) It applied the AHP and Fuzzy Comprehensive method to evaluate 5 entrances green landscape, obtaining landscape quality:Zhongshan Gate entrance and Yangtze River Bridge entrance's landscape quality is good, Youfang Bridge Flyover entrance and Dongyangfang Flyover entrance's landscape quality is general, Tiexin Bridge Flyover entrance's landscape quality is bad. Landscape effect of Nanjing entrances was general and needed to be improved.(5)It summarized advantages and Disadvantages of entrance green landscape, and gave countermeasures. First, it proposed optimizations from the whole, and then took Tiexin Bridge Flyover as an example to design the Optimization Program of plant-landscape, in order to provide reference materials to other cities.
