The golf course has many problems that are a pollution of river, a extinction of habitat by destructing a forest and a simplication of species composition. Therefore, this study was carried out to examine the ecological characteristics of vascular plants in construct-reserved site of golf course. The results were as follow. The vascular plants were summarized as 342 taxa; 86 families, 231 genera, 295 species, 42 varieties and 5 forma. In the results by the location environments of vegetation, Salix caprea community and wetland species like Persicaria thunbergii were appeared in the swamp. Especially, S. caprea will be made use of promoting a landscape. In the stream, Stephanandra incisa community has a functions like an ecological axis and a corridor of wild animals. The planting technique will be applied to using Atractylodes japonica and Ainsliaea acerifolia in the lower part of Pinus densiflora and Quercus mongolica. Because Rhododendron schlippenbachii and Convallaria keiskei grew by layer in Q. variabilis community, this will be made use of natural vegetation model. The rare plants were 2 taxa; Aristolochia contorta and Iris ensata var. spontanea. To preserve their community, we will prohibit a development and remove a threatening factor. The endemic plants were 4 taxa; Salix caprea, Clematis trichotma, Spiraea prunifolia for. simpliciflora and Weigela subsessilis. The naturalized plants were 19 taxa; Rumex crispus, Bildedykia dumetora and so on. To establish the quantitative management plan, we will obtain a ecological information about a naturalized plants in accumulating by season, community and land use pattern.

For biodiversity conservation, the importance of beta-diversity which is changes in the composition of species according to environmental changes has become emphasized. However, given the systematic investigation of species distribution and the accumulation of large amounts of data in the Republic of Korea(ROK), research on the spatialization of beta-diversity using them is insufficient. Accordingly, this research investigated the applicability of the Generalized Dissimilarity Modeling(GDM) to ROK, which can predict and map the similarity of compositional turnover (beta-diversity) based on environmental variables. A brief overview of the statistical description on using GDM was presented, and a model was fitted using the flora distribution data(410,621points) from the National Ecosystem Survey and various environmental spatial data including climate, soil, topography, and land cover. Procedures and appropriated spatial units required to improve the explanatory power of the model were presented. As a result, it was found that geographical distance, temperature annual range, summer temperature, winter precipitation, and soil factors affect the dissimilarity of the vegetation community composition. In addition, as a result of predicting the similarity of vegetation composition across the nation, and classifying them into 20 and 100 zones, the similarity was high mainly in the central inland area, and tends to decrease toward the mountainous areas, southern coastal regions, and island including Jeju island, which means the composition of the vegetation community is unique and beta diversity is high. In addition, it was identified that the number of common species between zones decreased as the geographic distance between zones increased. It classified the spatial distribution of plant community composition in a quantitative and objective way, but additional research and verification are needed for practical application. It is expected that research on community-level biodiversity modeling in the ROK will be conducted more actively based on this study.

To achieve carbon neutrality and restore the national environment, there is growing interest in policies to transform national land areas into green space, such as expanding nature-based solutions, increasing biodiversity, and improving ecosystem service functions. In addition to complying with international agreements such as the United Nations Framework Convention on Climate Change and the Convention on Biological Diversity, it is necessary to expand green spaces to achieve the 2050 Carbon Neutrality goal, which can be achieved by restoring the damaged land in an ecological way. However, it is challenging to implement green restoration in a systematic and active way due to conflicts of interest among landowners and lack of institutional support and advanced technology. Therefore, this study aims to develop a strategy to expand green restoration and implement it smoothly and systematically. This study examined the current status of green restoration in South Korea by investigating green restoration laws and systems and overseas trends, and by surveying the perceptions of 1,000 people selected from a pool of the public. The results of this study show that it is difficult to implement the green restoration efficiently because the laws related to restoration are scattered. According to the relevant legal plans, the perception and direction of restoration is to pursue a sustainable national land environment, allow people to benefit from nature, improve the quality of life, and nurture related industries and human resources. In the international community, it is mentioned that green restoration contributes to achieving the 2050 Carbon Neutrality goal, revitalizing green industries, developing and applying advanced technologies, maintaining consistency in restoration-related policies, expanding citizens' access to green spaces, and adopting nature-based solutions. Both experts and the public are aware of the seriousness of the damage to the natural environment and prefer restoration with human use rather than focusing on natural recovery. It is expected that this study will contribute to the future direction of green restoration and the implementation of tasks for the sustainable restoration of the national land environment and the zero-carbon era.

Yangjae stream was divided with Seoul and Gwacheon reach. Seoul reach was ecologically restored; however, Gwacheon reach was not. Similarity index of the bird communities between the two areas was relatively high, 79.9%. The dominant species in Seoul reach were Passer montanus, Pica pica, Paradoxornis webbianus and Anas crecca. The dominant species in Gwacheon reach were Passer montanus, Pica pica, Paradoxornis webbianus and Streptopelia orientalis. The different species was Anas crecca in Seoul and Streptopelia orientalis in Gwacheon. An eco-park was constructed along the stream of Seoul reach since 1996 but was not in Gwacheon reach; the number of species has increased in Seoul area($r^2$=0.846, p<0.01), but Gwacheon was not change($r^2$=0.023, p>0.05) since 1996. The number of individuals, however, was almost constant in both reaches(Seoul : $r^2$=0.211, p>0.05, Gwacheon : $r^2$=0.032, p>0.05). In Seoul reach, the ecological restoration of stream was helpful to increase bird diversity. The number of waterbirds such as herons, plovers, sandpipers and wagtails was higher in Gwacheon reach than in Seoul reach, but the number of ducks and songbirds was higher in Seoul reach than in Gwacheon reach. We suggest that the ecological restoration in Seoul area might have negative effects on sandpipers, plovers and wagtails inhabiting on the flood plain in stream, but positive effects on other species such as herons, ducks and songbirds. Especially, the increasing number of ducks was attributed to an artificial pond in flood plain. The difference in the number of Streptopelia orientalis between both reaches was owing to the habitat differences such as forest trees playing a role as patch in high revetment. From the present investigation, it could be concluded that the ecological restoration of the local stream must be carried out with consideration of water channels, sand banks and water front in addition to the high revetment for birds to attract diverse bird communities.

The phytosocialogical study on the coastal sand dune vegetation of the East Coast was carried out. 180 phytosociological relev$\acute{e}$s of 62 sites in the East Coast were used in this study. In addition, already published syntaxa and the phytosociological hierarchy in Korea and Japan were used and comparative analyses of syntaxonomy, synecology, syngeography, and syndynamics were performed in the study. In this study, the flora was investigated 30 families, 66 genera, 77 taxa and 3 vegetation types were identified : the coastal drift-line annual communities (Calystegio soldanellae-Salsoletum komarovii), the dune glasslands communities (Elymo-Caricetum kobomugi, Carex kobomugi typical community, Elymus mollis community, Calystegia soldanella community, Zoysia macrostachya community, Cynodon dactylon community, Carex pumila community), and the dune shrubs communities (Linario-Viticetum rotundifoliae, Vitex rotundifolia community, Rosa rugosa community). The aspect of transition in the coastal sand dune vegetation of the East Coast were identified as follows : (1) reduced constancy degree and cover degree of Glehnia littoralis in each community; (2) lack of Ischaemum anthephoroides in Linario-Viticetum rotundifoliae (3) simplified species composition in Vitex rotundifolia community. Unstable habitat condition by external interference seemed to has caused the reduction of 2 taxa, Glehnia littoralis and Ischaemum anthephoroides, that usually grow in the second dune. In addition, we found changes in the distribution of the dune shrub communities influenced by rising temperature of the East Coast as results of the global warming. The results on the distribution of the dune shrub communities in this study demonstrated that the limit of the Rosa rugosa community made $0^{\circ}$ 44'N to the North and the vegetative limit of the Vitex rotundifolia community made $0^{\circ}$ 28'N to the North, respectively compared with the previously phytosociological studies. This study investigated the coastal sand dune vegetation, syntaxonomy, habitat condition and human disturbunce of the East Coast, and this will provide important information as basic data for the coastal ecosystem.

본 연구에서는 식생 복원 유형별 토양동물의 변화를 알아보기 위해 비오톱이식공법, 산림표토포설, 소경목군락식재, 다층구조군락식재를 적용한 조사구와 이를 비교할 대조구를 선정하였다. 토양동물의 변화를 통한 토양동물자연도 분석 결과, 대조구는 환경에 민감한 동물군과 둔감한 동물군이 골고루 출현하고 있어 토양동물자연도가 높게 확인되었다. 식재를 통해 복원된 조사구의 경우, 비오톱이식공법의 토양동물자연도가 대조구와 유사한 수준까지 도달해 있었으며, 이보다 낮은 수준이긴 하나 소경목군락식재, 다층구조군락식재지역의 토양동물 또한 점진적으로 회복되고 있었다. 가장 낮은 토양동물자연도를 보인 조사구는 산림표토포설지역으로 확인되었다. 이를 통해 비오톱이식공법이 식재를 통해 복원된 조사구가 다른 조사구에 비해 토양동물의 회복이 좀 더 빨리 이루어지고 있음을 파악할 수 있었다. 이는 산림 내부의 숲을 그대로 굴취한 후 이식하는 것으로 표토와 심토의 일부분이 함께 옮겨지기 때문으로 판단된다.

도시하천은 산업혁명 이후 산업화 도시화가 진행되면서 무분별하게 복개 개발되어 지역주민들의 일상적 삶의 공간에서 멀어졌다. 최근 도시하천 복원사업이 진행되면서 접근성이 개선되고 쾌적한 환경으로 변모하여 사람들의 유입과 이용이 크게 늘면서 복원된 하천 주변 지역주민들의 커뮤니티 의식에 일정부분 영향을 미치고 있는 것으로 보인다. 본 연구는 도시하천의 복원이 지역주민들의 커뮤니티 의식에 어떠한 영향을 미치는지 규명하고자 수행되었으며, 이를 위해 최근 복원된 서울시 송파구 성내천을 방문한 방문객을 대상으로 설문조사를 시행하였다. 설문분석의 인자는 크게 성내천의 이용현황, 커뮤니티 의식(소속감, 연대의식, 정주의식), 복원사업 전후 비교(커뮤니티 의식변화, 지역효과 변화)등의 항목으로 구성되었다. 분석결과에 따르면 성내천 복원사업 후 일주일에 1~2회 이상 이용하는 방문객이 가장 많았다. 이들의 주된 방문목적은 '휴식 및 운동'이었고, '이웃이나 타인을 만나는 장소'로 이용하는 비율은 낮게 나타났으며, 성내천을 이용하는 주민들의 커뮤니티 의식은 대체로 높은 수준이었다. 방문빈도에 따라 세 집단으로 나누어 집단 간 커뮤니티 의식 차이를 분석한 결과, 집단 간 커뮤니티 의식 수준에 유의한 차이가 있었고, 특히 방문횟수가 많은 집단에서 커뮤니티 의식 수준이 높게 나타났다. 이 같은 결과로 볼 때 복원된 도시하천이 지역주민들의 적극적인 이용과 커뮤니티 활동을 활성화함으로써 지역에 대한 커뮤니티 의식을 고취하기 위해서는 주민들이 이용할 수 있는 적절한 시설과 프로그램 제공이 중요하다고 판단된다.
