This study was carried out for the purpose of creating a restoration plan to improve the ecological quality of the Changwon and Nam streams. Based upon the results of comprehensive diagnostic assessment, restoration priority was given to the upstream reach, where conservation status is relatively superior. Restoration level was usually determined to practice active restoration as conservation, and the states of both Changwon and Nam streams were not so good. Restoration plans, by reach, were classified into "upstream", "midstream", and "downstream" were suggested in both terms of horizontal section frame and vegetation-based on the result of diagnostic assessment and the reference information. "Upstream", "mid-stream" and the "downstream" of Changwon and Nam streams were classified into "small-gravel- mountainous", "small-sand-plain", and "small-clay-plain streams" respectively (based on scale, and substrate and slope of river bed). The spatial arrangement of vegetation was laid out in diagram form by reflecting micro-topography and the water level of the horizontal section of river. Information regarding species composition was recommended as dominant species, which appear frequently in three vegetation zones composed of herbaceous plants, shrubs and trees and sub-tree- dominated zones divided by reflecting disturbance regime, depending on position on the horizontal section of river. Moreover, there have been prepared not only plans to improve the terrestrial ecosystems around the streams but also plans to create ecological networks, which can serve to improve the ecologic quality of the whole regional environment by serving to connect streams and terrestrial ecosystems, a process probably necessary and definitely recommended to realize true (genuine) restoration. Plans for ecological parks and networks were prepared by mimicking the species composition of Alnus japanica community, Zelkova serrata community, Carpinus laxiflora community, Quercus aliena community, and Q. serrata community.

본 연구는 습지가 크게 부족한 우리나라의 현실에서 습지 복원에 요구되는 기초 생태 정보를 얻기 위해 수행되었다. 이러한 목적을 이루기 위해 본 연구에서는 비교적 온전한 둠벙을 유지하고 있는 충북 괴산 일원의 둠벙을 대상으로 습지 복원을 위한 기초생태정보를 수집하였다. 둠벙에 성립한 식생 중 인위적 간섭으로 성립한 식생을 제외하고 자연적으로 성립한 식생을 대상으로 식생의 수평적 분포를 종합하면, 수역에는 개구리밥군락, 마름군락, 가래군락, 보풀군락, 긴흑삼릉군락 및 송이고랭이군락, 수변에는 고마리군락, 골풀군락, 여뀌바늘군락, 환삼덩굴군락, 큰개여뀌군락, 물억새군락, 달뿌리풀-갈대군락 및 도루박이군락, 지하수위가 중간 정도인 관목식생대에는 찔레꽃군락, 조팝나무군락 및 갯버들군락, 지하수위가 높은 곳에 성립한 교목 및 아교목식생대에는 신나무군락과 버드나무군락이 성립하는 경향이었다. 수집한 식생정보에 기초하여 서열화한 결과, 수생식물 우점 식분, 습생대식물 우점 식분 및 수변식물 우점 식분으로 대별되는 경향이었다. 이러한 식분을 이루는 주요 식물군락의 생태적 위치와 종 조성을 생태연못을 조성하기 위한 대조생태정보로 제시하였다. 나아가 습지가 발휘하는 기능을 통해 그것의 중요성과 복원의 필요성을 논의하였다.

A phytosociological vegetation survey was conducted in July to September 2011 in order to examine the vegetation community structure in Mt. Ohseo area. It was aimed to provide basic data for the effective vegetation conservation by analyzing the importance, species diversity and community similarity of the forest community in Mt. Ohseo for each layer, followed by the classification of the actual forest vegetation. According to the cluster analysis, the community type of Mt. Ohseo was classified into a total of 4 vegetation communities: Pinus densiflora community, Cornus controversa-Quercus serrata community, Miscanthus sinensis community, and Quercus mongolica community; the vegetation type 4 showed the lowest species diversity index of 0.5236, and vegetation type-2 showed the highest species diversity index of 0.6606. The community similarity between Quercus mongolica community and Pinus densiflora community showed the highest 0.679, and the community similarity between Quercus serrata community and Pinus densiflora community and between Quercus serrata community and Quercus mongolica community showed the levels of 0.5, respectively.

A method of conserving the vegetation at Mt. Chonggye was established to persue a practical management of the natural ecosystem by the vegetative composition analysis. As a result, the vegetation of surveyed areas was classified into two communities and four subcommunities in Mt. Chonggye. Potentilla fragarioides var. major community, known as the roadside plant community, distributed near trails under heavy human impacts. Potentilla fragarioides var. major community included two subcommunities : Digitaria sanguinalis-Ambrosia artemisiifolia var. elatior subcommunity and Rhus chinensis subcommunities. In these communiyies, there were many naturalized plant species such as Aster pilosus and Artemisia princeps var. orientalis, known as heliophilous plant. Results indicated that the vegetation had been affected by intensive human activities. It is necessary to control the naturalized plant species such as Aster pilosus for conservation of the ecosystem and nature in this area. Quercus mongolica community, a common coppice woodland in central Korea, was mostly distributed around mountain tops and ridges above 529 m altitute. In the valley where the forests well conserved, the Quercus mongolica community contained the Syneilesis aconitifolia-Hemerocallis lilioasphodelus subcommunity. On the other hand, Potentilla dickinsii subcommunity was dominated in dry rocky ridge areas. In these areas, however, the vegetation and forest soil was not properly managed for conservation.
