Abstract
Some of alien plants, which were introduced from foreign countries, have caused problems in Korea. Invasion of these alien plants in the ecosystem threatens the habitat of endemic species, reducing biodiversity, and causing a disturbance in the ecological system. In urbanized areas of campus universities, a diverse range of organisms were found and a comparison between the sites, near roads or housing sites were made because the campuses provided a large biotope. Although the campus had been exposed to interferences like gardening, it was also a place for most organisms to live in an active floating population due to free access. This research investigated the flora of alien plants that appeared in Beakseok University, Sangmyung University, Hoseo University and Dankook University, and relationship between the distribution of alien plants and the campus and green areas and distance from the highway. The total number of plant species and naturalized species found in the four universities was 189 and 43 species. Those of Dankook University were 136 and 35 species, Hoseo 108 and 25 species, Sangmyung 103 and 31 species, and Baekseok 97 and 26 species, respectively. The abundance of natural plants for each respective university tended to be higher as it became closer to the highway. Also, the closer the walking distance to the university, the greater the tendency for the degree of similarity to be higher. As a result, we may conclude that the distribution of alien plants and anthropogenic activities may be closely related.
