Research On The Improvement And Maintenance Management Of Highway Plant Landscape

One place of material and spiritual civilization construction level are reflected in many aspects.The highway construction is undoubtedly an important content,since the highway is generating some social and economic benefits.Along with the continuous strengthening of China’s economic power,the development of infrastructure is getting important.In China,the construction of highway has made great progress,and the expressway has become an important support for modern transportation.From the ecological point of view,the greening of the highway can not only effectively control the soil and water loss,reduce the noise intensity,but also can absorb some automobile off-gas and restore the species diversity.From the perspective of landscape,the greening makes the highway and the surrounding environment integrated,reducing the interference of glare and creating a comfortable travelling environment for drivers.With respect to the culture,the greening of the highway can reflect the unique charm of local aesthetics.The continuous progress of the social economy makes more efforts are devoted to the construction of highway,accompanied by the increasing attention to the social and environmental protection.The greening of the highway is becoming more and more serious,which has aroused widespread concern.First of all,based on the current situation and trend of plant landscape of the highway at home and abroad,this paper put forward the purpose and significance of this study.In regard of the plant landscape composition,they can be divided into four parts,including the plant landscape of central partition,the plant landscape of two sides of the road and slope,the plant landscape of interchange area,combined with the plant landscape of service area and toll station area.Secondly,on the basis of these four functional areas,the selection and configuration patterns of plant landscape in each region are unique and should follow the corresponding rules.This research focused on the overall environment of the plant landscape of highway,summing up the basic principles that plant landscape should follow in the process of design and configuration.Accomplishing the design,transformation and upgrading of plant landscape in the highway by dividing different areas,the author emphatically clarified the reasons and effects of upgrading.Thirdly,combing the actual situation of Fujian Province with relevant analysis,the research concluded the main problems existing in the maintenance management of highway plant landscape,mainly in watering,cultivating soil,weeding,fertilization,pest control,replanting and shaping pruning.After that,the author put forward some more particular solution and raised the optimization recommendations on the maintenance management of highway plant landscape.This article in the concrete highway greening data collection,analysis and dissertation writing process,using a variety of methods to analyze and summarize the status of similar studies both at home and abroad,with depth and systematic study of the concept of greening the highway,the role of plant selection,plant allocation patterns and other aspects,and in-depth study of the actual case of highway in Fujian.The main achievements of the research are summarized as follows:1.The problems of highway greening in Fujian mainly focus on watering,soil-cutting,weeding,fertilization,pest and disease control,replanting and plastic trimming.Therefore,measures such as watering,soil-cutting,weeding,fertilization and pest and disease control should be taken timely and with due respect to the laws of plant growth to maximize the effectiveness of conservation and management work.2.Expressway greening has four functions of ensuring traffic safety,natural protection,environmental protection and social benefits.Proposed five major principles of highway plant selection,respectively,is to protect traffic safety is the first important meaning;to native species is preferred,but does not rule out other options;planted species to pest problems have a certain degree of resistance;have a higher ornamental Value;vitality,management difficulty appropriate.3.From the composition classification of the highway plant landscape,it can be divided into four parts:plant landscape of the central divider,sides of the road,plant landscape of the slope,plant landscape and service area of the inter-exchange area,plant landscape of the toll station area.Based on the division of these four functional areas,the selection and allocation of plant landscape in each area have their own characteristics and should follow the corresponding rules.4.Freeway plant landscape conservation management of the main objectives of two,namely,reduce costs and increase efficiency.The ecological environment and site conditions faced by expressway vegetation are rather special.Therefore,due to adherence to the conservation and management thinking of "one-third construction and seven-maintenance".5.In this paper,a number of highway in Fujian Province as the research object,summarized in the previous summary of the principles and methods applied to the actual project,from the side to verify the correctness of the theory and methods.
