  • 국내에 분포하는 대표적 침입외래식물인 돼지풀과 단풍잎돼지풀이 나타내는 유전적 변이양상을 파악하기 위해 국내집단을 중심으로 돼지풀 157개체와 단풍잎돼지풀 46개체로부터 핵 rDNA의 ITS(Internal Transcribed Spacer)지역 염기서열을 분석하였다. 그 결과 돼지풀에서는 총 18개의 ITS 유형이, 단풍잎돼지풀에서는 4개의 유형이 각각 검출되었다. 돼지풀의 경우 각각의 ITS 유형간에는 1bp에서 7bp까지 차이가 나는 것으로 확인되었으며, 단풍잎돼지풀의 경우 각 유형 간에 1bp에서 2bp의 차이가 발견되었다. 돼지풀의 국내집단에서 18개에 이르는 다양한 ITS 유형이 검출되었다는 사실은 이 종이 우리나라에 여러 차례 반복해서 유입했기 때문인 것으로 풀이된다. 한편 일부 ITS 유형은 유전적 재조합에 의해 형성되었을 가능성이 있으며, 각각 한 개체에서만 발견된 12개의 소수 유형들은 점돌연변이 또는 그에 뒤이은 유전적 재조합에 의해 국내에서 독자적으로 기원했을 것으로 추정된다. 본 연구를 통해 침입과정에서 나타나는 돼지풀의 진화적 변화를 이해하는데 필요한 유용한 유전적 기초정보가 확보되었다.

  • In this study vegetation structure was monitored focusing on slanting surface of stream for the purpose of developing a management plan and ecological restoration of small stream in Paju. The study was conducted by types of geographical structure, yearly flora, naturalization rate changes, actual vegetation changes, plant community changes. Slope area of small stream in Paju was varied in the slope range of $10{\sim}35^{\circ}$. The survey results of yearly flora showed that 37 species appeared in 2000, 55 species in 2001, 95 species in 2002, and 125 species in 2003. Therefore, the trend of continuous increase of flora each year was observed. In the case of yearly changes of actual vegetation, indigenous wetland herb community including Phragmites communis$(19.99%{\rightarrow}18.42%{\rightarrow}19.60%)$ did not show substantial changes in the area, while the influence of controlled flora such as Humulus scandens$(8.86%{\rightarrow}5.26%{\rightarrow}9.73%)$, and Ambrosia artemisiifolia$(1.06%{\rightarrow}1.43%{\rightarrow}6.93%)$ were increased. The vegetation structure investigated by 18 preset belt-transects also indicated that Phragmites communis and Miscanthus sacchariflorus were maintaining the status or decreasing the population, while the population of Humulus scandens, Ambrosia artemisiifolia, Setaria viridis, and Erigeron canadensis were greatly increased. Our proposal management to restore ecology is as follows: first, preservation and restoration of Phragmites communis landscape; second, restoration of potential stream vegetation community; third, selection and removal of controlled plants.

  • The purpose of this study is to offer the raw data for establishing the management and restoration plan by objective surveying and analysing the flora distributed in Seoak District, Gyeongju National Park, Korea. The flora summarized as 411 taxa including 92 families, 285 genera, 363 species, 2 subspecies, 41 varieties and 5 forms. The rare plants designated by Korea Forest Service were 2 taxa including Exochorda serratifolia and Potentilla discolor. The Korean endemic plants were 3 taxa including Philadelphus schrenkii, Lespedeza maritima and Weigela subsessilis. The specific plants by floristic region were 16 taxa including Asplenium sarelii, Pyrrosia petiolosa, Vitex negundo var. incisa and so forth. The target plants adaptable to climate change were 2 taxa including Lespedeza maritima and Carpesium macrocephalum, and the plants with approval for delivering oversea were 4 taxa including Exochorda serratifolia, Glycine soja, Lespedeza maritima and Weigela subsessilis. The naturalized plants were 51 taxa including Phytolacca americana, Viola papilionacea, Lamium purpureum and so forth. The invasive alien plants were 3 taxa including Ambrosia artemisiifolia, Aster pilosus and Lactuca scariola. NI(Naturalized Index) was 12.4% of all 411 taxa of surveyed flora in this study and UI(Urbanized Index) was 15.9% of all 321 taxa of naturalized plants in Korea. Potentilla discolor in rare plant, Philadelphus schrenkii in endemic plant and Dictamnus dasycarpus in specific plant were established the conservation plan. Whereas, invasive alien plants such as Ambrosia artemisiifolia, Aster pilosus and Lactuca scariola should be removed as soon as possible. The damaged sites in Seoak District were divided between wildfire area and farmland. To restore a forest fire site, we will have to apply a natural renewal and community planting. In case of farmland, we will have to do ecological planting using native species and constrcut a forest wetland.

  • 2003년 4월부터 8월까지 경상북도 영천시 금호읍 황정리, 관정리, 구암리, 영천시 도남동에 속한 금호강 주변의 황정 습지에서 식생 구조를 조사하였다. 현존식생도에 나타난 군락은 달뿌리풀 군락, 물억새 군락, 버드나무-선버들 군락, 달뿌리풀-물억새 군락, 돼지풀 군락, 환삼덩굴 군락, 물억새-줄 군락, 달뿌리풀-갈대 군락, 갯버들-달뿌리풀 군락, 왕버들-버드나무 군락, 노랑어리연꽃-줄 군락, 줄-달뿌리풀 군락 등 총 12종류였는데, 군락별 분포 면적은 달뿌리풀 군락이 49.46 ha(11.03%)로 가장 넓고, 물억새 군락 15.32 ha(3.42%), 버드나무-선버들 군락 8.13 ha(1.81%), 달뿌리풀-물억새 군락 6.42 ha(1.43%) 등의 순이었으며, 줄-달뿌리풀 군락이 0.19 ha(0.04%)로서 가장 좁았다. 표조작에 사용된 식생 조사표상 상재도에 의해 구분할 수 있는 군락은 달뿌리풀 군락과 돼지풀 군락인데, 달뿌리풀 군락은 노랑어리연꽃 아군락 및 왕버들 아군락으로 구분되었다. 달뿌리풀 군락의 식별종은 달뿌리풀, 물억새, 고마리, 미나리, 겨풀, 개갓냉이 등이고, 돼지풀 군락의 식별종은 돼지풀, 금강아지풀, 닭의장풀, 쇠방동사니, 바랭이, 도꼬마리, 개망초, 망초, 매듭풀, 토끼풀, 자주개자리 등이며, 노랑어리연꽃 아군락의 식별종은 노랑어리연꽃, 줄, 큰고랭이, 물꼬챙이골 등이고, 왕버들 아군락의 식별종은 왕버들, 버드나무, 갯버들 등이었다. 황정 습지는 전형적인 하천 습지로서 비교적 보전 상태가 양호하나 습지 주변의 경작지(과수원)에서 배출되는 농약 등으로 인해 분포하는 식물의 생육에 영향을 받을 것으로 생각된다. 벼과와 버드나무속을 포함한 수생 및 습생 관속식물의 분포 면적이 넓은 황정 습지는 다양한 생물들의 서식처로 이용되고 아름다운 하천 경관을 제공하며 간접적으로 금호강의 수질 정화에 기여하므로 보존 가치가 있는 습지로 판단된다.

  • This study was carried out for management of the invasive alien plants in Mt. Inwang located in central Seoul. The invasive alien plants are 11 families, 34 genera, 30 taxa, and they are 10.8% of the total vascular plants(314 taxa). The ecosystem disturbed plants designated by the Korea environment ministry are 6 taxa : Rumex acetosella, Lactuca scariola, Ambrosia trifida var. trifida, Ambrosia artemisiifolia, Aster pilosus and Eupatorium rugosum. In the life-form, herbaceous perennials are 13 taxa(35.3%). In the continent of origin, the species from America are 20 taxa(58.8%). In the introduction time, the species of third period are 14 taxa(41.2%). In the diffusion grade, 5 grade species are 14 taxa(41.2%) and they are wide spread species. Mt. Inwang was designated as ecological scenery conservation area of Seoul in 2007. But Mt. Inwang is in high danger by the spread of invasive alien plants and ecosystem disturbed plants, due to artificial factors such as development pressure and the occurrence of byway trail. Therefore, Mt. Inwang needs systematic management of invasive alien plants and monitoring of long-term changes.

  • The purpose of this study was conducted in order to provide the necessary basic data, to establish management solutions and to improve biodiversity by calculating similarity index, urbanization index (UI), and disturbed index (DI) to understand current status of naturalized and invasive alien plants in Eulsukdo, Maekdo and Samnak ecological parks in Busan, South Korea. The numbers of naturalized plants identified in these parks were 76 taxa; 20 families, 53 genera, and 76 species. As a result of the similarity index analysis, the most similarity level (83.0%) was obtained at Eulsukdo and Maekdo parks. The numbers of invasive plants identified in the two parks were 11 taxa; Rumex acetosella L., Sicyos angulatus L., Solanum carolinense L., Ambrosia artemisiifolia L., Ambrosia trifida L., Hypochaeris radicata L., Lactuca serriola L., Solidago altissima L., Symphyotrichum pilosum (Willd.) G.L.Nesom, Paspalum distichum L., and Humulus scandens (Lour.) Merr. Overall, UI and DI were 28.6% and 66.7%, respectively, indicating that the ecosystem disruption was serious.
