  • A Sustainable Structured wetland Biotop (SSB) system was constructed on the floodplain of Kyungan stream in December, 2006. It purifies polluted water of Keumeo stream which flows into the stream. Water were sampled once a month at inlet and outlet from December, 2007 to December, 2008. $BOD_5$, SS, T-N and T-P were analyzed. Plant and fish species of the system were monitored twice during the period. Average influent and effluent BOD5 concentration was 6.2 and 2.2 mg/L, respectively and BOD5 removal was 50.8%. SS concentration of influent and effluent was averaged 10.1mg/L and 1.5mg/L, respectively and SS abatement amounted to 77.0%. Average influent and effluent T-N concentration was 4.9mg/L and 2.9 mg/L, respectively and T-N retention was 50.8%. T-P concentration of influent and effluent was averaged 0.386mg/L and 0.107mg/L, respectively and T-P removal amounted to 77.0%. Twenty two plant species were naturally introduced into the system, however, they didn't make up a significant portion of the plant populations compared with the planted species. Dominant plant species were in the following order; Phragmites communis > Typha latifolia > Iris pseudoacorus > Persicaria thunbergii. Five families and 15 species of fish were observed in the system including Chinese minnow (Moroco oxycephalus) which inhabits in clean water. Six more fish species were monitored in the system compared with ones living in Kyungan stream. Amphibia and reptiles accounted for 11 species of 4 orders and 7 families including Korean Salamander (Hynobius leechi) which also lives in cleanwater.

  • Urban wetlands provide various ecosystem services and are subject to restoration and creation projects due to their increased value in the context of climate change. However, the vegetation structure of wetlands is sensitive to environmental changes, including artificial disturbances, and requires continuous maintenance. In this study, we conducted a vegetation survey of three wetlands created as part of a project to restore urban degraded natural ecosystems and monitored the quantitative changes in wetland vegetation structure using an unmanned aerial vehicle. The vegetation survey revealed 73 species in Incheon Yeonhui wetland, and the change in vegetation composition based on wetland occurrence frequency was 11.5% on average compared to the 2018 vegetation survey results. The vegetation survey identified 44 species in Busan Igidae wetland, and the proportion of species classified as obligate upland plants was the highest at 48.8% among all plants, while the proportion of naturalized plants accounted for 15.9% of all plants. The open water surface area decreased from 10% in May 2019 to 6.7% in May 2020. Iksan Sorasan wetland was surveyed and 44 species were confirmed, and it was found that the proportion of facultative wetland plant decreased compared to the 2018 vegetation survey results, and the open water surface area increased from 0.4% in May 2019 to 4.1% in May 2020. The results of this study showed that wetlands with low artificial management intensity exhibited a tendency for stabilization of vegetation structure, with a decrease in the proportion of plants with high wetland occurrence frequency and a relatively small number of new species. Wetlands with high artificial management intensity required specific management, as they had a large change in vegetation structure and a partially high possibility of new invasion. We reaffirmed the importance of continuous monitoring of vegetation communities and infrastructure for wetlands considering the function and use of urban wetlands, and restoration stages. These research results suggest the need to establish a sustainable wetland maintenance system through the establishment of long-term maintenance goals and monitoring methods that consider the environmental conditions and vegetation composition of wetlands.

  • As sustainable development and environment-friendly efforts in large-scale development projects emerge as major interests at home and abroad, man-made wetlands and eco-park facilities have been newly planned or created when developing reclamation districts recently. In this study, based on findings from a comprehensive review of relevant studies and planning cases, the basic direction and objectives of the plan were developed. A comprehensive analysis on the status of ecological environment and demographic and social environment showed that the planned site is in a process of migrating from early stages of reclamation to middle stages. It was planned for the eco-park to function as a major base along an ecological network consisting a freshwater lake and rivers and streams flowing into the lake in Hwaong District. Through a master plan and sectoral plans were planned according to desalination levels after reclamation. Then, habitats for livings organisms were also planned. The eco-park, the planned site, is also in a process of migrating from the early stages to middles stages. By creating an eco-park that considers post-reclamation ecological environment changes, natural succession processes will be preserved, which is expected to help local ecosystems to restore their functions on their own over a relatively long period of time and enable to observe the restoration process.

  • National park is one of the important types of protected area management systems established by IUCN and a management model for effective conservation and sustainable use of natural and cultural heritage in countries around the world, and it assumes important roles in conservation, scientific research, education, recreation and driving community development. This study takes Liaohe National Park in China, a typical representative of global coastal wetlands, as a case study, and uses python technology to collect travelogues and reviews of visitors from Mafengwo.com, Ctrip.com, Go.com, Meituan.com and Dianping.com as a source, and the text spans from 2015 to 2022. The results show that wildlife resources, natural landscape with river and sea, wetland ecology and fishing and hunting culture of northern China are fully reflected in the perceptions of visitors to Liaohe National Park. However, there is still much room for improvement in terms of supporting services and facilities, public education and tourists' experience and participation in Liaohe National Park. In this paper, we use python data visualization technology to study the public perception of wetland wildlife as the theme, and grasp the satisfaction, spatial distribution, activity content and emotional tendency of the public in the process of wetland wildlife as the theme, so as to better promote the Liaohe National Park to better carry out the public experience while strictly adhering to ecological protection, and to provide the Liaohe National Park with a better opportunity to This will provide scientific basis for the Liaohe National Park to play a better role in ecological civilization construction and education of ecological civilization awareness.

  • 상주 공검지는 8세기에 축조된 고대 유적 저수지로서 습지보호지역으로 지정되어 있다. 이곳에서 지속가능한 보전 전략을 수립하는데 필요한 기초자료를 수집하기 위하여, 현존 식생을 분류하고 식생도를 작도하며 식생의 구조적 특징을 파악하고 환경과의 관계를 규명하였다. 공검지 습지보호지역에서는 저습지, 하천, 산림, 초지, 농경지, 과수원 식생에 속하는 총 26개 식물군집이 분류되었다. 탈경향대응분석 (detrended correspondence analysis) 결과에 따르면 습지 식생의 구조는 주로 수심과 인간 교란에 따라서 영향을 받았다. 저수지 습지에서는 통발, 마름과 같은 부수식물과 연꽃, 부들류와 같은 정수식물이 수면을 완전히 피복하고 있었다. 2014년 이후에 점차 정수식물과 습생식물의 분포 면적이 늘어나는 육역화가 빠르게 진행되고 있었다. 습지보호지역의 지속가능한 보전과 복원을 위하여, 지형과 식생을 복원하고, 수문 체계를 회복시키며, 습지로부터 산지까지의 생태계 연결성을 회복한 것이 필요하다고 생각된다.

  • The purpose of this study is to investigate and analyze a conservation state and a sustainable use of coastal wetland in Sindu-ri Tae-an, using the plant community structure analysis and the awareness result of local residents by published paper. To investigate a forest structure in Sindu-ri area, twenty plots were set up and surveyed. The community, is divided by three groups. The divided groups are Robinia pseudoacacia(I), Pinus thunbergii-Robinia pseudoacacia(II), Robinia pseudoacacia(III). Survey site I is simple canopy layer and deteriorative forest. Survey site II is grassland and swamp, where Pinus thunbergii-Robinia pseudoacacia is dominant trees of vegetation. Robinia pseudoacacia is competition species with Pinus thunbergii in survey site II. Survey site III is barren land(sand-hill) where main species is Robinia pseudoacacia. As a result, survey II district is considered as the most suitable for the conservation of species diversity. It is proposed in this paper that the ecological nature trail would be connected in survey site I and II for environmental education. The local residents of Tae-an, where natural environment is well-conserved, prefer conservation to development of the region. In case of Tae-an, where the condition of the natural environment is well conserved and the development potential exists, the development is in harmony with the environmental education program.

  • 다양한 생태계 서비스를 제공할 수 있는 습지는 지속가능한 수질 개선 및 기후변화로 인한 영향의 완충작용 등 중요한 자연기반해법기술로 간주되어 왔다. 특히 토지이용 변화, 기후 변화 및 수문 변화에 따른 영향 저감을 위한 습지 보전의 중요성은 부각되었으나 경관규모에서의 거시적 자연기반해법기술 가능성의 검토가 미비하였다. 이에 본 연구에서는 생태 네트워크 분석을 통한 공학적 솔루션 제공 가능성을 검토하기 위해 습지경관 가상 서식종의 이동모델을 기반으로 형성된 습지 생태네트워크를 이용하여 토지이용변화에 따른 생태네트워크의 구조적, 기능적 특성 (연결성, 이동 효율성 및 집단화 계수)이 어떻게 변화하는지 분석하였다. 이를 위해 습지 밀도가 다른 네 구역의 토지이용변화를 가정하여 두 가지의 초기 면적조건에 대한 각 구역의 동시다발적 토지이용변화를 통해 생태 네트워크 특성의 변화를 분석하였다. 모든 분석결과에서 습지밀도가 높은 구역이 파괴된 경우 생태네트워크의 평균 연결성과 이동 효율성이 크게 감소하였으며, 특히 허브 (매우 높은 연결성을 지니는 노드)가 포함된 구역의 습지가 제거될 때 급격한 감소가 발생하는 것을 확인하였다. 반면, 집단화 계수는 증가하는 것으로 관찰되었다. 이를 통해 토지이용변화에 따른 생태네트워크에 대한 영향을 평가할 수 있으며 특히 향후 매개중심성 분석을 추가하여 적합한 대체습지를 조성할 수 있는 자연기반의 공학적 솔루션을 제공할 수 있을 것으로 사료된다.
