摘要:

道路是景观生态系统的主要组成部分之一,高密度的公路系统通过改变自然景观特征、干扰生态系统物质与信息交流、诱发水土流失、破坏动植物栖息环境、加快生物入侵对生态系统造成巨大影响。为了提高公路交通建设的科学技术水平,探索资源节约、环境友好的新型公路交通发展模式,通过湖北神宜公路改扩建工程项目的科学总结与理论提升,提出了“近自然绿道”的技术与工程措施。研究表明:围绕“路景相融、自然神宜”的建设目标,坚持“亲近自然、文化传承、科学创新、和谐发展”的公路建设新理念,实践“环境保护、交通安全、经济与社会和谐发展与教育示范”“近自然绿道”的和谐道路建设目标,可以较好地实现公路建设中的环境保护和经济发展双赢的目标,实现社会经济可持续发展

Abstract:

Roads are a part of most landscapes,and high road densities create large ecological impacts by altering landscape patterns,interrupting ecological flows,inducing soil erosion,damaging inhabit of environment,and speeding up bioinvading.To advance the scientific and technological ability in highway construction and explore a new highway traffic approach of resource saving and environmentally friendly,we undertook a study to explore the potential for protecting ecosystems during the construction of roads in Shennongjia region of Hubei Province from 2008 to 2009 supportted by Ministry of Communications,Traffic Office and Highway Bureau of Hubei Province,and proposed a nearnatural greenway concept and scientific and technological harmonious system of highway.As in the use of ecological corridors,the new strategy emphasizes the need to decrease the impact of road construction on plant and animal habitats by protecting existing natural habitats and using local species for revegetation of the land surrounding the roads.It also emphasizes the need to improve traffic safety,promote local tourism and economic growth,and provides a demonstration to citizens (including bureaucrats) of the need for environmental protection both during and after road construction.After 6 years of monitoring,the result indicates it is possible to implement a winwin approach which combines environmental and economic perspectives by protecting the environmental,ecological,educational,cultural,and esthetic aspects of the reserves.The new road system is extended in forestry land,fascinating party,and natural landscape with the clear rivulet aside.Sustainable development,based on economic growth and sound environment,is increasingly essential.To satisfy both socioeconomic and ecological needs,governments face a difficult balancing act.The new approach is a particularly promising way to achieve this balance,because,as we have shown,it greatly increases environmental protection around the road and promotes socioeconomic development by encouraging flows of people and goods between formerly isolated regions.Although the environmental benefits are difficult to quantify in economic terms,they are clearly significant from a sustainability perspective.Based on the success of the projects described in this paper,the government is increasingly adopting the use of nearnatural greenway systems in environmentally sensitive areas.These projects will provide a rich source of new data that can be used to further explore the benefits of the new approach,and also provide an opportunity to monitor the projects and determine how well their performance holds up in the long term
