1.前言近年来,随着我国社会经济的飞速发展,公路交通以其特有的优势,在我国“大交通”体系中占有十分重要的地位。公路里程的日益增加,交通量的日益增大,公路网的日益密集,无疑为搞活流通、发展我国的市场经济开辟了广阔的发展天地。但是,为国民经济和发展做出巨大贡献的同时,公路也给沿线的环境带来了许多不利的影响,引发了一系列的环境问题。如水土流失、生态平衡失调、气候异常、汽车废气和尘埃注入大气等,从而使人类生存的环境质量下降,以致危害人体健康,破坏生物资源,影响工农业正常生产。因此,寻求一条公路建设与环境保护协调发展的途径已经是刻不容缓。探索实现协调发展的方法与对策,不仅具有理论上的研究价值同时具有深远的现实意义。
1. Foreword In recent years, with the rapid development of social economy in our country, highway transportation occupies a very important position in the system of “big traffic” in our country with its unique advantages. The increasing mileage of the highway, the increasing traffic volume and the increasingly intensive road network have undoubtedly opened up a vast space for development in our country’s market economy. However, while making great contributions to the national economy and development, roads have also brought a lot of unfavorable influences on the environment along the route and triggered a series of environmental problems. Such as soil and water loss, ecological balance disorders, climate anomalies, automobile exhaust and dust injected into the atmosphere, so that the quality of human existence and environmental degradation, resulting in endangering human health, damage biological resources, affecting the normal production of industry and agriculture. Therefore, it is urgent to seek a coordinated development of highway construction and environmental protection. To explore ways and measures to achieve coordinated development not only has the theoretical value of research but also has far-reaching practical significance.
