Transport Routes as a Factor in the Transformation of Flora (for the Example of the Khabarovsk Territory)

In the article the peculiarities of the flora of transport lines (road and railways) of Khabarovsk Territory and their influence on flora of adjoining communities are considered. The authors analyzed the peculiarities of flora formation on various structural elements of roads such as roadway; embankments and slopes; negative elements of relief (side drain and drainage ditches); adjoining phytocenoses. The particularities of roadside flora of roads and railways are considered in comparison. The authors give examples of road participation in the distribution of native and alien species. Peculiarities of roadside flora formation are described in the article taking into account ecological characteristics of the region: climatic factors and zonal types of communities. The main trends in the distribution of alien species are indicated. The authors analyzed the existing approaches to assessing the potential danger of quarantine species and concluded their potential threat to the region.
