영문 초록

This study carried flora investigation out the Seongnagwon of scenic Site No. 35. in downtown Seoul that were managed a periodic landscaping. As results, taxa of total 69 families, 141 genera, 163 species, 20 varieties, 1 forma were recorded and 27 taxa of Neophyten were appeared. And Neophyten were analyzed the life-form, disseminul-form, origin and introduction mode. First, from the perspective of life-form’s analysis, high frequency of therophyte appearance in high rate due to human activity such as grass mowing. This results in the disturbance of numerous habitats as port, landfill and roadside. Second, in case of disseminul-form’s analysis, D4 and D1 were accounted for 85% of the total. Especially, D4 compared to others naturally move and spread the seeds that are relatively unfavorable. Therefore these results were spread by human activity(intentional or unintentional) such as planting a garden plant, imported a external soil ect. were considered. Third, in case of origin’s analysis, origin of the 6 region were identified. And nA(45%) and Eu(33%) were accounted for 78% of the total. These places are similar with geographical position and climatic of East Asiatic Province include South Korea and it is more benefit than plant species from flora of other climate region for adaptation and invasion. Fourth, introduction modes are human being’s activity (intentional, unintentional) and directly related with ergasiophygophyten and kenophyten and those are 92% of introduction modes. Especially, escape from the local area which is already introduction shows they are adapted to local natural environmental condition and it include ecological characteristic which is easy to distributional spread and then it demand to appropriate management policies.
