公路绿化是公路建设的一个重要组成部分。随着精神文明、物质文明建设水平的提高,公路建设不但要满足交通运输功能的要求,而且对美学、心理学方面也提出了更高的标准,因此绿化工程将起到重要作用。一方面公路绿化有利于净化空气、调节气候、防止水土流失、保持路基稳定、延长公路寿命,另一方面公路绿化还有美化路容、诱导视线、防眩、创造良好的行车环境等功效。换言之,公路绿化对充分发挥公路效益及保护公路环境都有重要的作用。
Highway greening is an important part of highway construction. With the improvement of the level of spiritual civilization and material civilization, highway construction not only meets the requirements of transport functions, but also sets higher standards in aesthetics and psychology. Therefore, greening projects will play an important role. On the one hand, highway greening is conducive to purifying the air, regulating the climate, preventing soil erosion, maintaining roadbed stability, and prolonging the life of the highway. On the other hand, the greening of roads also has the functions of beautifying the road, inducing sight, preventing glare and creating a good driving environment. In other words, highway greening plays an important role in giving full play to highway benefits and protecting the road environment.
