Research On Plant Disposition Pattern In The Road Green Space In The Central Region Of Shanxi Province

Urban road green space plant configuration is the important part of urban green space system, strengthen the road greening, optimize the structure of road greening tree species and landscaping tree plant configuration mode is an important means of improving urban ecological environment, urban road green space tree species in quality area as the research object, through to the city of article 23 of distance,3 TiaoCi distributor roads,29 branch,1159 quadrat investigation, the amount and type of 77 kinds of greening tree species were analyzed, and optimize the urban road green space tree species of plant configuration mode on the basis of summarize and optimization, and sums up the suitable for quality and even the middle region of Shanxi Province road greenbelt plant configuration optimization model.The main results were as follows:1, the quality of road greening tree species,77 kinds, Joe filling ratio of about 1.9:1, look from actual application number shrubbery than about 5.4:1.According to the view of flower 49 species of ornamental characteristics points, trees species,8 species,29 kinds of type of tree species, view stems 5 tree species, comparison and analysis from five aspects of 49 species protection.2, different position from the analysis of different grade road road green space suitable tree species structure, it is concluded that major, one, branch road green space distribution in a vehicle, used by roadside greenbelt and roadside greenbelt status of different plant detail.3, summary quality existing 59 kinds of road greenbelt plant configuration mode, the major four plate WuDai type a total of eight kinds of patterns, three board four belt have 29 kinds of pattern, for different location of the green with different forms of greening, there are 15 kinds of pattern of junior three zones;A total of 3 one plant configuration mode;The branch has four different modes.4, puts forward the road green space optimization of tree species, including the backbone tree species increased 14, generally increase 21 kinds of tree species,30 species of afforestation trees in potential value. When next greening can be targeted to choose different grade road green belt position suitable tree species.In the update of trees, on the basis of the proposed road green space optimization model 63 kinds, including four board WuDai type 16 kinds of mode, three board four belt type 29 kinds of mode, junior three zones type with a plate two belt type 18 kinds of patterns.
