Study On The Green Maintenance And Design Of The Expressway’s Mainline In Guangdong Province

With the continuous extension and development of expressway in China, the construction of road caused great influence to the local ecological environment. In order to reduce the damage to the natural environment, based on recovery of green ecology and landscape design of green vegetation cover, it’s necessary to maintain and improve these functions of green plants in the follow-up process of construction, which is also essential for the virescence maintenance on highway. It is the key point of this paper to make a positive and feasible suggestion for the greening and maintenance of the expressway, which can be used in the design, investment, use and maintenance process.First of all, the article summarizes the general situation of highway development at home and abroad and ways to improve the highway traffic, so as to introduce the domestic and foreign highway greening conservation situation.Secondly, this paper analyzes the unfavorable factors of main expressway greening environment, and carries out a systematic research about function, content, scope and characteristics of the xpressway greening maintenance and management. Key and difficult aspects of green maintenance are highlightened. And the artcile confirms that ecological conservation is infeasiblein in the afforestation and maintenance of freeway.Besides, through the investigation and analysis on the content and form of greening maintenance, it is difficult to maintain the high way with human power in the long run; afforestation and maintenance of freeway construction is difficult due to the harsh environment, which means the proportion of mechanic and intelligence should be continuously increased. At the same time, irescence maintenance labor intensity, amount of labor and cost should be reduced so as to improve the greening design rationality and sustainability and advocate ornamental plants suitable for the highway.Finally, through the two sections of the road, problems involved in the process of green maintenance are analyzed from different angles analysis and the advantages and disadvantages of are compared, through which functions, demands and benefits are summerized in order to fully embody the importance of greening design in expressway greening projects.Green design must be made in conjunction with the use, maintenance, ecology, and future value, which could be improved in the process of design, feedback, improvement, and application. As a result, the various parts of the virescence maintenance conditions could be vigorously improved, scientific and rational allocation of plant could be achieved,and virescence maintenance facilities will be improved. This paper comprehensively reflects the common problems reflected by freeway virescence maintenance, puts forward some positive proposals for these problems, has its value in a certain range, adds the relevant research in Guangdong Province, and it will be feasible for virescence maintenance, design and research in Guangdong Province and even in a national scale.
