ABSTRACT

After the modern industrial revolution, rivers in cities became covered and disappeareddue to the pressure to develop them. Likewise, their function which is to serve as the basis of naturalecology system in the cities began to be damaged. This research demonstrated that there are a total of268 categories when it comes to the list of plants, including 64 families, 179 genera, 230 species, 36varieties, and 1 subspecies. When the relative abundance of the plants that were found at the targetresearch site was studied, the secondary survey demonstrated Bromus japonicus 22.97, Artemisia princeps var. orientalis 16.76 and Erigeron annuus 15.69 while third survey demonstrated Digitaria ciliaris 26.78,Ambrosia trifida 16.29 and Aster pilosus 14.31. There were 54 species of naturalized plants that appeared. Analysis demonstrated annual plant 23 classification category (43%), perennial 11 classificationcategory (20%), multi-perennation 17 classification category (31%), woody plant 3 classificationcategory (6%) and others. When the naturalized plants that were found at the target research site wereanalyzed by the place of origin, North America and EU took up 76%, which accounts for 3/4 of the allthe naturalized plants. At the target research site, naturalization degree of 5 pertained to 22classification category (41%), which was the highest, followed by 19 classification category (35%) withnaturalization degree of 3, 8 classification category (15%) with naturalization degree of 2 and 5classification category (9%) with naturalization degree of 4 in the order mentioned. Flora ofJungnangcheon did not manifest any change compared to 10 years ago. Thus, it is necessary to increaseof biodiversity efforts to improve SeoulCity’s natural environment and cityscape.
