Study On Planning And Design Of Landscape Of Affiliated Green Field On Both Sides Of The High-grade Highway

The ecological corridor system of the high-grade highway mainly consists of the main body of the road and the affiliated green field on both sides.At present,research on the ecological corridor system of the highway mainly focuses on two aspects:the improvement of the engineering technology of the main road and the improvement of the landscape effect,and there are few theories and examples regarding the affiliated green field on both sides of the highway.As an important part of the ecological corridor system,the affiliated green field on both sides of the road plays an irreplaceable role in improving the ecological system along the road.Therefore,this paper chooses the planning and design of the affiliated green field on both sides of the high-class road as the research object,which will carry out analysis from the following aspects.First,through the analysis and summary of relevant literature and data at home and abroad,this paper makes clear of some basic concepts such as high-class highway,affiliated green field on both sides of the road,landscape,ecological corridor,and so on.Under the guidance of theories like landscape ecology,landscape aesthetics,environmental psychology,environmental physiology,this paper proposes the content,methods and technical routes of the research;Secondly,through the analysis and comparison of three existing cases,this paper analyzes the advantages and disadvantages of the plan from the aspects of regional culture,natural ecology,humanism,aesthetic value and so on,which has some reference significance for the landscape design of auxiliary green field on both sides of high-class highway;Again,summarize the principles,types and strategies of the design of auxiliary green field on both sides of the high-class highway.The principles of the design include taking nature as priority,people-oriented,regional,taking local conditions in to consideration,comprehensive and sustainable;according to the usage types of lands,the landscape is divided into cultivated land landscape,forest land landscape,water landscape and so on,and the corresponding planning and design method are summarized;According to the height difference between our sight and landscape,cultivated land landscape can be divided into three types:higher than the shoulder of the road,regional shoulder and equal to shoulder of the road.The key point of the design is to ensure people's visibility so they can enjoy the mountains and scenery in the distance;According to the characteristics of the terrain,forest landscape can be divided into three types:mountain land,flat land and side slope.The design focuses on the sequence of plants and hierarchy of the space,while taking into account the needs of viewing landscapes and safety of driving cars,and properly set up landscape nodes;According to the wideness of water surface,water landscape can be divided into two kinds:large water surface and small water surface.The key point of the design of large water surface is the highlight of the water surface,while taking to the characteristics of water landscape and ecological environment protection of riverbank into consideration;the key point of the design of small water surface is the creation of wetland landscape so as to maintain its original ecology;Finally,taking the landscape planning and design of both sides of Wusha section of G318 in Guichi District as an example,conclusions are practiced,and the landscape layout of Guichi District is shown as "one axis,two lines,five areas and four nodes".
