【摘要】 随着高速公路建设的迅速发展和人们对环境保护意识的日益提高,公路环境的生态防护和综合恢复技术越来越受到全社会的高度重视。尤其是西部干旱、半干旱地区,气候干燥、水土流失严重、植被稀疏、生态环境脆弱,高速公路生态绿化显得格外重要。本文在恢复生态学原理的基础上,提出了高速公路生态绿化的概念,强调高速公路施工过程中,应采用现代恢复生态原理和生物技术手段,对工程创伤形成的区域进行科学、合理的恢复;基于破坏植被的生态恢复与重建理论、技术途径,探讨了高速公路生态恢复与重建措施。通过对甘肃省的生态环境、自然环境以及已建高速公路路域环境的综合调查,分析了公路建设对干旱、半干旱地区沿线大气、水、声环境以及植物、生物多样性的影响;指出在高速公路建设中,目前公路生态绿化存在的主要问题是生态恢复理念相对落后,对路域生态环境的变化规律认识不足。并在此基础上,分析干旱、半干旱地区高速公路生态绿化的特点。结合干旱、半干旱地区高速公路生态绿化区域所处的地理环境、自然条件,从生态恢复的角度,对高速公路不同区域(边坡、中央分隔带、立交区、两侧绿化带、服务区、收费站等)绿化的功能、作用、基本要求和原则以及防护技术措施进行了分析研究,提出了适合于干旱、半干旱地区高速公路的生态绿化措施。在高度重视生态环境保护的今天,本文的研究为干旱、半干旱地区高等级公路生态绿化提供了依据。更多还原

【Abstract】 With high-development in expressway construction and expanding attentions to environment, the preservation of ecology and recovery techniques of highway environment have been attached great importance by the society. The west area whose arid and semi-arid climate has made soil and water loss, rare vegetation and poor ecological condition, which put forwards the preservation of ecology to expressway in the west is more important than in the other areas.In this paper, the conception of ecological greening is put forward which emphasize the area where is building expressway should be restored by the ecological technology under the guidance of restoration ecology thesis, and some expressway restoration ecological methods are also put forward based on the restoration and reestablishment ecology thesis.According to the investigation to natural environment and the environment along the expressways in Gansu Province, how the highway construction influences the air, water, sound, vegetation, and the variety of creature in arid and semi-arid area is analyzed, which reflects that the main problems in ecological greening of highway are the out-of-date idea and the poor knowledge on restoration ecology, and then the characteristics of expressway ecological greening in arid and semi-arid area are analyzed and put forward.Analyzing the functions, effects, basic demand, principles and protection techniques of greening in different area on expressway (slope, central median, interchange area, service area, toll station) in arid and semi-acrid areas with the geographic environment, the ecological greening methods for acrid and semi-acrid are put forward. The research in this paper is contributed to high-level highway ecological greening in acrid and semi-acrid.更多还原
