道路的生态学影响域范围研究进展

道路建设在促进社会经济发展、方便人们生活的同时,也带来了环境污染、动植物栖息地破碎等严重的生态学后果,道路生态学随之成为生态学研究的重要前沿领域之一。20世纪90年代,道路生态学的研究重点转移到道路的生态学影响域等相关领域,包括生态学影响范围、类型及其形态、格局等。大量研究表明,道路对周边动植物等生物因子以及周围环境中土壤、水分和空气成分等生态因子的影响范围各不相同,道路生态学影响域的范围随着道路的利用率以及各生态因子种类及其变化特点而有所不同。在综述国内外学者对道路生态学影响域范围研究结果的基础上,建议中国应开展道路生态学影响域的综合研究,并将研究成果应用于道路规划的实践中,推动国内道路生态学研究的发展。参58

Review on ranges of ecological road-effect zones

Road construction has brought environmental pollution,caused habitat fragmentation for wildlife and plants,and contributed to other severe ecological problems in adjacent areas;meanwhile it has pro moted social and economic development and improved daily life for human beings.Road ecology has be come one of the most important frontier fields in ecological research.In the late 1990's,the focus of road ecology research shifted to an ecological road-effect zone and other related fields including the ecological influence of range,type,form,and pattern of roads.Many studies have shown that in the peripheral surroundings the various road systems impact soil properties,moisture,air composition,and other ecological factors,as well as species of wildlife and plants,differently.The range of the ecological road-effect zones produced by a road system also varies along with traffic volume,types of ecological factors,and specific change patterns of each factor.After summarizing both domestic and overseas studies on the range of the ecological road-effect zone,this paper recommended that comprehensive research should be carried out in China with research achievements being applied to road system planning practices so as to improve the development of road ecology in China.Ch,58 ref.]
