近几年,我国高速公路迅速发展,对促进沿线地区政治、经济和文化的发展起到了积极作用。但另一方面,公路建设、营运对该地区也产生了负面影响:如植被受到破坏,坡面侵蚀度加大,各种废弃氧化物所形成的有毒物质和气体直接或间接地破坏着生态环境。因此,高速公路绿化美化和环境保护已成为公路建设可持续发展的重要问题。 高速公路绿化是在保障快速行车的前提下使司机和乘客获得美的享受。同时高速公路绿化还有以下作用:绿化环境,防风固沙;稳固路基,防止水土流失;减轻污染,保护环境,有效降低地表温度等。
In recent years, the rapid development of our country’s expressways has played a positive role in promoting the political, economic and cultural development along the areas. However, on the other hand, highway construction and operation have also had a negative impact on the area. For example, if vegetation is damaged and slope erosion is increased, the toxic substances and gases formed by various abandoned oxides directly or indirectly destroy the ecological environment . Therefore, highway greening and environmental protection has become an important issue of sustainable development of highway construction. Highway greening is to allow drivers and passengers to enjoy the beauty of the United States under the premise of ensuring fast driving. At the same time highway greening also has the following effects: greening environment, wind and sand; stabilize the roadbed to prevent soil erosion; reduce pollution, protect the environment and effectively reduce the surface temperature.
