摘　　要：交通廊道是连接城市的重要纽带,是促进城市群发展、经济发展和信息交流的重要通道。京津冀城市群作为我国继长三角、珠三角之后的第三大城市群,城市群内交通路网发展迅速;道路交通廊道的建设导致物种的生境发生变化,对沿线的群落造成影响,甚至破坏了生态系统的完整性与连通性,阻碍了物种的交流、迁移与扩散。通过对京津冀城市群内G95高速张家口-承德段、G4高速石家庄-邯郸段、G103国道北京-天津段及沿海公路秦皇岛-天津段4条重要交通廊道沿线的物种实地调查,发现物种76科171属230种,采用多样性分析方法,分析了道路交通廊道沿线物种多样性的影响因素。结果表明,城市群内交通廊道沿线的物种相似性随着样点间生境的差异而降低;京津冀城市群内交通廊道沿线的物种相似性随着样点间距离的增加而降低;交通廊道沿线各样点的人为干扰因素是导致物种相似性低的重要因子。The traffic corridor is an important link connecting several cities,and also an important channel to promote the development of urban agglomeration,economic development and information exchange.The Beijing-Tianjin-Hebei urban agglomeration is the third largest urban agglomeration which is following by the Yangtze River Delta and the Pearl River Delta in China.The transportation network of urban agglomeration develops rapidly.The construction of road traffic corridors has led to change in the habitats of species,affecting communities around the urban agglomeration,and even destroyed ecosystem integrity and ecosystem connectivity,also it hindered the exchange,migration,and spread of species.In this paper,through field surveys of species along the four important traffic corridors in the Zhangjiakou-Chengde Section of the G95 highway,Shijiazhuang-Handan Section of the G4 highway,Beijing-Tianjin Section of the G103 national highway,and the Qinhuangdao-Tianjin Section of the coastal highway,we found 76 families,171 genera and 230 species.Though the diversity analysis methods,we analyzed the influencing factors of species diversity along road traffic corridors.The results showed species similarity along traffic corridors in urban agglomerations reduced by the habitat differences between sites;along the transportation in the Beijing-Tianjin-Hebei urban agglomeration,species similarity decreased by the distance between the two samples increased;human disturbance was the important factor that causes low species similarity at points along the traffic corridor.
