Research On Plant Landscape Of The Community Park In Nanjing

Community park is the highest frequency of utilization of close park by the citizen. on one hand,it offer public places of recreation, relaxation and communication,on the other hand, it plays an important role in reliefing current community environment question and protecting the urban ecology.This paper taking the plant landscape in the green space from16community park in NanJing, divide this grden green space into four types including green space around the buildings and squre,road-greenbelts, waterfront green space and ornamental green space.This paper analyzes the present condition of NanJing community park green space from the aspects of the configuration of plants planted in landscape and the plant community, by surveying Nanjing urban waterfront green space.And with the theories of Aesthetic, Landscape, Ecology, Botany and so on, the model which is based on AHP to assess the plant landscape in Nanjing community park green space with fuzzy synthesis evaluation is established.24typical plant communities landscape was evaluated and analyzed through this model in this paper.finally it summarizes the characteristics and the insufficiency of plant landscape in community park greenspace and gives a optimizational suggestion.The main conclusions of this paper were as follows:(1) According to the analysis of the configuration of plants landscape planted in the13pieces of four kinds of greenbelts (green space around the buildings and squre,road-greenbelts, waterfront green space and ornamental green space)in Nanjing community park, it was concluded the advantage about the greenspace of NanJing community park that the species of flower-watching plants and colorful plants are abundant,and With the high levels of green land ratio and the lack that the seasonal change in plants is not distinct in summer and winter,and vertical greening is not enough.(2) According to the analysis of plant community in greenapace of NanJing community park,we can conclude that the species of landscape plant is relatively abundant,but dominant species in four kinds of greenspace are resemble. Cinnamomum camphora,Magnolia grandiflora,metasequoia and cedar is applied the most frequent in arbor-layer of greenspace.The same situation happened in the bush-layer too. There is a low percentage of application of native tree species in the greenspace of community park,and the regional feature of the plant landscape is not obvious.(3) Using AHP with fuzzy synthesis evaluation to assess green space of NanJing community park. From four aspects of ecology, landscape, social service and cultural value, this paper formulates comprehensive index system of plant landscape in green space of NanJing community park quality and sets up the model of AHP with fuzzy synthesis evaluation on green space. Then it gives comprehensive evaluation indexes of24plant landscape in green space of community park.(4) According to the results of the analysis of plant configuration, plant community analysis and quality comprehensive evaluation, this paper gives several advices to the construction of green space in NanJing community park.
