After the modern industrial revolution, rivers in cities became covered and disappeared due to the pressure to develop them. Likewise, their function which is to serve as the basis of natural ecology system in the cities began to be damaged. This research demonstrated that there are a total of 268 categories when it comes to the list of plants, including 64 families, 179 genera, 230 species, 36 varieties, and 1 subspecies. When the relative abundance of the plants that were found at the target research 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 classification category (20%), multi-perennation 17 classification category (31%), woody plant 3 classification category (6%) and others. When the naturalized plants that were found at the target research site were analyzed by the place of origin, North America and EU took up 76%, which accounts for 3/4 of the all the naturalized plants. At the target research site, naturalization degree of 5 pertained to 22 classification category (41%), which was the highest, followed by 19 classification category (35%) with naturalization degree of 3, 8 classification category (15%) with naturalization degree of 2 and 5 classification category (9%) with naturalization degree of 4 in the order mentioned. Flora of Jungnangcheon did not manifest any change compared to 10 years ago. Thus, it is necessary to increase of biodiversity efforts to improve SeoulCity's natural environment and cityscape.

본 연구는 강원도 인제군 매봉 지역 일대를 중심으로 식물상 조사를 수행하였다. 관속식물은 73과 173속 228종 3아종 28변종 6품종으로 총 265분류군으로 조사되었다. 분류군별로는 양치식물이 5과 14분류군, 나자식물 1과 3분류군, 쌍자엽식물 60과 182분류군, 단자엽식물 7과 29분류군으로 확인되었다. 주요 식물로는 특산식물 고려엉겅퀴(Cirsium setidens), 무늬족도리풀(Asarum versicolor), 병꽃나무(Weigela subsessilis) 등 8과 9분류군, 희귀식물은 멸종위기종(CR) 긴개별꽃(Pseudostellaria japonica), 애기가물고사리(Woodsia glabella) 2분류군, 위기종(EN) 댕강나무(Abelia mosanensis) 1분류군, 취약종(VU) 멱쇠채(Scorzonera austriaca subsp. glabra) 1분류군, 약관심종(LC)인 과남풀(Gentiana triflora var. japonica), 금강제비꽃(Viola diamantiaca), 너도바람꽃(Eranthis stellata) 등 9분류군으로 총 13분류군이 확인되었다. 환경부지정 특정식물종은 V등급 1분류군, IV등급 2분류군, III등급 13분류군이 확인되었다. 귀화식물은 단풍잎돼지풀(Ambrosia trifida), 달맞이꽃(Oenothera biennis), 닭의덩굴(Fallopia dumetorum) 등 6과 11분류군이 확인되었다. 산림청에서 지정한 특별산림보호대상종은 댕강나무(Abelia mosanensis), 참배암차즈기(Salvia chanryoenica)가 확인되었다. 유용식물로는 용도를 모르는 96분류군(36.2%)를 제외하면 169분류군(63.8%)이 자원식물로 이용가치가 있는 것으로 나타났다. 이들을 용도에 따라 구분해보면 식용 114분류군(33.2%), 섬유용 5분류군(1.5%), 약용 82분류군(23.9%), 관상용 33분류군(9.6%), 사료용 94분류군(27.4%), 산업용 1분류군(0.3%), 염료용 3분류군(0.9%), 목재용 11분류군(3.2%)으로 확인되었다.

A floristic study on the vascular plants from Mt. Seounsan region, which ranges from Seoun-myeon, Anseong-si, Gyeonggi-do to Baekgok-myeon, Jincheon-gun, Chungcheongbuk-do, was conducted 9 times in total, from April 2014 to October 2015. Based on the voucher specimens, it was revealed that the vascular plants in this region comprised 501 taxa: 97 families, 306 genera, 439 species, 5 subspecies, 51 varieties, and 6 forma. Among these plants, 185 taxa were recorded for the first time from this region. 8 Korean endemic species including Asarum patens (K.Yamaki) B.U.Oh, Scutellaria insignis Nakai, and Weigela subsessilis (Nakai) L.H.Bailey were found in this region. 5 taxa of rare plants designated by the Korea Forest Service, including Iris ruthenica KerGawl., Leontopodium leontopodioides (Willd.) Beauverd, and Tricyrtis macropoda Miq., were also found. 11 taxa of floristic regional indicator plants in the $3^{rd}$ to the $5^{th}$ degrees were identified. In addition, 46 taxa of naturalized plants were recorded, and 2 taxa of ecosystem disturbance plants, which were Ambrosia trifida L. and Aster pilosus Willd., also found.

The studies were conducted to obtain the basic information of the effects of pollutants on plant species and to select the plant species showing specific responses to the pollutants. For these purposes, paraquat, ammonium, and cadmium as a source of oxidative stress, nitrogen toxicity, and heavy metal toxicity respectively were treated to the plant species. Among the tested plants, Lamiaceae, Brassicaceae, and Caryophyllaceae were tolerant to paraquat, whereas Poaceae and Asteraceae were sensitive. Especially Mosla dianthera of Lamiaceae, Hemistepta lyrata and Aster pilosus of Asteraceae, and Paspalum thunbergii of Poaceae showed higher tolerance than others. Paraquat resistance was related with life style, overwintering capacity, so perennial and biennial species showed higher tolerance than annual species. In response to ammonium, Poaceae showed higher resistance while Fabaceae and Caryophyllaceae showed sensitiveness. Weed species having tolerance to ammonium were Echinochloa crus-galli var. praticola, Panicum dichotomiflorum, Setaria glauca, Chenopodium album, and Solanum nigrum, while Mosla dianthera, Arenaria serpyllifolia and Perilla frutescens var. japonica showed sensitiveness. In the response of plant species to cadmium, Digitaria sanguinalis, Amaranthus lividus showed higher resistance, whereas Galinsoga parviflora, Plantago asiatica, Ambrosia trifida, and Paspalum thunbergii showed sensitiveness. The injured degree on germination stage by pollutants did not related with injured degree on matured stage. During germination, the root elongation was more sensitive than shoot elongation by pollutants, paraquat, ammonium, and cadmium.
