Study On Landscape Planning And Design Of Expressway Entrances And Exits In Mountainous Cities

China is a country rich in mountain resources,a large number of mountainous cities are widely distributed.Because of the particularity of the geographical environment,the construction of these mountainous cities has been developing slowly,and the construction of expressway entrances and exits has long been lagging behind.With the implementation of the national new urbanization strategy and growing social demands,expressway entrances and exits in mountainous city with unique landscape resources usher in new development opportunities.At present,many mountainous cities have actively carried out landscape construction in order to improve the environment of expressway entrances and exits,enhance the image of the city,enhance their own charm and attractiveness to promote economic development.The landscape construction of many expressway entrances and exits caused serious damage to landscape and landscape resources of expressway entrances and exits,due to the lack of scientific landscape planning and design as a guide,but backfire,resulting in a variety of problems.With this background,this article actively carried out landscape planning and design research on expressway entrances and exits in mountainous cities,strived to explore suitable landscape planning and design methods for China’s expressway entrances and exits in mountainous cities,and provided scientific and rational guide for future expressway entrances and exits landscape construction of this type.This article followed the basic idea of "asking questions-theoretical analysis-practical analysis-problem solving",and the main contents were seven chapters.The first chapter introduced the research background,the purpose and significance of the study,the research object and the research content,summarized the current research situation at home and abroad,and determined the research method and research frame of the article.The second chapter elaborated the concepts related to the landscape planning and design of expressway entrances and exits in mountainous cities,and put forward the commonly used theories in the landscape planning and design of expressway entrances and exits in mountainous cities.The third chapter analyzed the main problems in the present situation of expressway entrances and exits landscape in mountainous cities in China.The fourth chapter analyzed the landscape characteristics of expressway entrances and exits in mountainous cities in China,and summarized the landscape elements and landscape characteristics of them.On the basis of the previous chapters,the fifth chapter drew the principle of landscape planning and design of expressway entrances and exits in mountainous cities,and put forward the landscape planning and design method of them.In the sixth chapter,the landscape planning and design of expressway entrances and exits in mountainous cities from the fifth chapter were studied and evaluated by taking the landscape planning and design of Lishui County West expressway entrance and exit of Sichuan Province as an example.In the seventh chapter,on the basis of summarizing the content of this article,the whole research process was evaluated and rethought,and the shortcomings and improvement direction of the article were put forward.The article put forward that the contents of the landscape planning and design of the mountainous city should include the natural landscape and the cultural landscape.The design should achieve the following five goals of firstly with distinctive mountain features and high recognition,secondly respecting and protecting nature with high degree of integration of natural landscape and artificial landscape,thirdly reflecting the local cultural tradition with profound cultural heritage,forthly creating a better driving and living environment for the users,local animals and plants with excellent landscape environment,fifthly building a calling card to attract transit persons and meet the needs of the users.The design should follow the principles of adhering to overall coordination,adhering to respecting regional cultural traditions,adhering to enhancing the image of the portal,adhering to constructing urban green space,adhering to traffic safety priorities,and formulate scientific and rational landscape planning and design strategy from three aspects of the construction of the establishment of the whole landscape system and the whole landscape image,the creation of the characteristics in important areas,and the creation of architectural style,characteristic structure and infrastructure,thereby create a unique landscape style of expressway entrance and exit in mountainous city.
