【摘要】：高速公路高效安全、快捷舒适,并能产生巨大的社会效益和经济效益,对国民经济建设有着深远和广泛的影响,是地区间交往最重要的交通手段之一,但是在其建设和营运的过程中也会对周边环境产生诸多不良的影响。本文阐述了高速公路及高速公路绿化的概念。论述了我国高速公路的绿化从最初的种行道树,边坡绿化发展到涵盖了整个高速公路的各个功能区段的正规化、专业化发展趋势,并简要介绍了国外公路绿化的优秀成果,阐述了湖南高速公路建设发展过程的重要节点及对湖南经济的深远影响,分析和总结出湖南地区高速公路绿化的四大问题:设计与施工及管理脱节;强调短期效果,忽视长期效果;重视建设,忽视养护;专业技术水平有待提高。论述了高速公路绿化具有的交通安全、景观改善、自然防护、环境保护、生产功能和社会效益六大方面的功能;提出了高速公路植物选择的五大原则;并从温度、土壤、水分、污染四个方面阐述了高速公路植物环境限制因子及选择要求。本章从高速公路五个重要的组成部分,中央分隔带绿化、路堑路堤护坡绿化、路侧防护林带绿化、互通互交区绿化、服务区绿化,分别从设计要求、植物选择、植物配置三大方面进行深入的理论研究。最后以湖南省大浏高速为研究对象,介绍其项目概况,指导思想及设计原则,再详细阐述绿化景观设计内容,并对其中的部分节点做详细的研究,将前文所总结归纳出的原则与方法应用于实际项目中进行绿化景观设计。希望通过本文的研究,能让高速公路绿化工作的参与者和建设者们,力求学习和借鉴国外发达国家在高速公路绿化规划建设方面取得的成功经验及其发展趋势。力求找出湖南地区高速公路绿化的比较成功的经验性总结,进一步了解湖南地区的绿化植物选择及配置,并为湖南地区乃至全国高速公路植物选择及配置方式供理论上和案例上的借鉴和依据,提高高速公路绿化建设水平,使高速公路真正成为一条美丽而生态的景观通廊。
[Abstract]:Expressway is efficient, safe, fast and comfortable, and can produce huge social and economic benefits. It has far-reaching and extensive influence on national economic construction. It is one of the most important means of communication between regions. But in the course of its construction and operation, it will also have a lot of adverse effects on the surrounding environment. This paper expounds the concept of highway and highway greening, and discusses the greening of expressway in our country from the initial planting of road trees. The development of slope greening covers the formalization and specialization of all functional sections of the whole expressway, and briefly introduces the excellent achievements of highway greening abroad. This paper expounds the important nodes in the development process of Hunan expressway construction and its far-reaching influence on Hunan economy, analyzes and summarizes four major problems of highway greening in Hunan area: the disconnection between design and construction and management, and the emphasis on short-term effect. Ignoring the long-term effect, paying attention to the construction, neglecting the maintenance, the professional technical level needs to be improved. This paper discusses the functions of highway greening in six aspects: traffic safety, landscape improvement, natural protection, environmental protection, production function and social benefit. This paper puts forward five principles of plant selection in expressway, and expounds the limiting factors and selection requirements of plant environment in expressway from four aspects of temperature, soil, moisture and pollution. Greening of central separation zone, slope protection of cutting embankment, greening of roadside shelterbelt, greening of intercross area and greening of service area, respectively, according to design requirements, plant selection, Finally, taking Daliu High-speed of Hunan Province as the research object, introducing its project general situation, guiding ideology and design principle, then expounding the design content of greening landscape in detail. Some of the nodes are studied in detail, and the principles and methods summarized above are applied to the greening landscape design in the actual project. To enable highway greening participants and builders, To learn and learn from the successful experiences and development trends of highway greening in developed countries, and to find out the more successful experiences of highway greening in Hunan. To further understand the selection and allocation of greening plants in Hunan, and to provide theoretical and case reference and basis for the selection and allocation of expressway plants in Hunan and even the whole country, so as to improve the level of highway greening construction. Make the highway become a beautiful and ecological landscape corridor.
