高速公路是人们进入一座城市的第一印象,是一座城市无形的明信片,关系着一座城市的市容市貌。高速公路和市中心的街道一样应该保持清洁,环境优雅。高速公路也是城市治理改善的一个重大项目,为了使其更加美观,体现城市的卫生文明程度,保证高速公路交通运输安全,保护城市的环境,需要在公路两旁栽植一些花草来绿化。基于此,以北方为研究主体,讨论了北方高速公路绿化的功能与设计原则。
Expressway is the first impression that people enter a city. It is an invisible postcard of a city, which is related to the appearance of a city. The highways should be as clean and elegant as the streets in the city center. The expressway is also a major project to improve urban governance. In order to make it more beautiful, embody the hygienic civilization of the city, ensure the traffic safety of the expressway and protect the environment of the city, some flowers need to be planted on both sides of the road for greening. Based on this, taking the north as the main body of study, the functions and design principles of highway greening in the north are discussed.
