Overview of invasion patterns of alien plants and predominant influence in road-region ecosystem

We introduced the distribution patterns of invasion plants on the road-region ecosystem,relating to the grades of the road,light levels,degrees of interference,and types of land-uses.We summarized the control proposals of the invasion plants,and put forward some scientific problems to be solved in this field.A large number of researches showed that various factors of road-region ecosystem had very close relationships with the distribution and diffusion of invasion plants.Therefore it had important significance to promote the control of the alien plants through understanding the regular patterns of road region ecosystem deeply.
