Analysis On Urban Greening And The Application Of Urban Greening Tree Species In Cangzhou

Urban landscape can improve the city’s ecological environment, enhance theenvironmental quality, and beautify the city life. Perfect urban landscape design withoutrich variety of plant materials and reasonable plant configuration, urban landscapinggreening trees species survey of urban landscape can provide rich plant materials for urbangreening design, and provide scientific basis for urban greening tree species selection,realize the sustainable development of urban landscape construction. Cangzhou urbanlandscape undertakings have developed rapidly, and landscaping greening trees species ismore and more abundant, but due to a lack of ornamental species planning, there are someproblems yet, such as monotone greening form, unreasonable application for tree speciesusing. Based on investigation on the utilization and spatial distribution of landscape plantsin Cangzhou City, the existing main problems were analyzed and some basic principles andviewsabout green trees in city planning. Counter measures to upgrade the level of speciesutilization were discussed in the course of building Cangzhou.First of all, it mastered byanalysis of existing tree species and the application of native trees and application effectand analyzed various types of tree species growth.Secondly, the existing problems wereanalyzed including species more but diversity not high in some areas.Thirdly, According toinvestigation concluded:(1) There are26families,38genera,153species of current treesfor urban landscaping greening tree species in Cangzhou City;(2) the present situation ofthe application of landscaping greening trees species for1:0.66, liana species species usingproportion than11.1%, evergreen leaves for1:4.63,, indigenous tree species using ratio for10.5%.(3) The greening tree species grow well overall in Cangzhou, only somesalt-tolerant of greening tree species showed poor in cangzhou city, The greening treespecies of Park green land growth overall the road green space and individual residentialgreen space.Finally concluded the urban greening standards of tree for the main tree species, shrubas the collocation of tree species, flowers as the role of the ornament, One can enter, have aseat, greening tree species covering an area of less, much of the sky. Promote local treespecies, does not support the tree transplanting, But you can plant went; Advocates thestereoscopic greening, does not support the four seasons evergreen, Appreciate the fourdistinctive seasons landscape effect of the spring flowers, the trees are green in summer, inautumn the leaves are yellow, winter tree branches left. Park can be appropriate tointroduce foreign species, we should pay attention to prevention and control of plantdiseases and insect pests, Especially the longicorn and prevention of greening tree species.With combination of reality of Cangzhou, it proposed some basic principles about species selection and applications, prompted the cangzhou city has the characteristic of urbangreening construction better.
