  • 2010년 9월 21일 오전부터 서울과 인천 등 수도권 지역에 최대 200mm가 넘는 집중호우가 내렸다. 이로 인해 도림천에서는 하천 복원 공사가 한창이었으나, 공사가 진행된 지점에서 자연형하천 공법의 훼손이 심각하게 발생하였다. 본 연구에서는 집중호우로 인한 자연형하천 공법의 훼손 현황을 현지조사를 통해 살펴보고, 이의 원인을 검토, 분석하여 복구대책 수립에 지침이 되도록 하였다. 자연형하천 공법의 훼손은 주로 하천의 수리적인 안정성을 고려하지 않고 설치함으로써 인위적으로 흐름에 지장을 초래하기 때문에 발생하였다. 흐름의 유속을 고려하지 않는 수생식물 식재, 하도 내에 설치된 진입계단, 전망데크, 불투수성의 자전거길 및 저수호안공의 훼손은 추후 흐름의 유속과 와류 등을 고려한 수리적인 안정성 확보가 중요함을 시사하였다. 한편, 저수호안에 식재한 갯버들+자연석 호안공은 이번 호우에도 어느 정도 대응 가능하였음을 감안할 때, 흐름의 유속이 빠르다고 하여 자연석 호안공을 시멘트로 메워 식생을 도입하지 않았던 공법에 대한 재검토가 필요함을 알 수 있었다.

  • In this work, soil environment policy which should be taken into account at brownfield redevelopment projects was deduced from investigation on their environmental impact assessment statements. Soil contamination sources such as small-scale factories were found at a few large-scale brownfield projects, so contaminated soils did often exist at these sites. Especially, military facilities within the sites caused severe soil contamination problems. Therefore, soil environment policy was presented in detail to solve soil contamination problem at brownfield redevelopment projects. Furthermore, land-use planning focusing on greening (soil and vegetation) should be pursued at brownfield redevelopment projects in order to maximize environmental benefits of greenspace.

  • In order to understand the condition of mostly-degraded evergreen broad-leaved forests(EBLF) and to make a restoration plan of EBLF in the Korean warm temperate, the distribution of EBLF and forest vegetation types have been investigated and the categories of degraded levels have been set. The coverage of the EBLF in the Korean peninsula was approximately 10,285ha based on the existing literature review and the actual vegetation map. Forest vegetation types have been investigated at thirty-two area of the south coast and inland in the warm temperate region. As a result, The forest vegetation was classified as 52 types; 26 types of EBLF, 13 types of semi-evergreen broad-leaved forests, 9 types of deciduous broad-leaved forests, 4 types of evergreen coniferous forests. The categories of degraded levels were divided into 8 levels and 14 sub-levels according to the importance percentage(I.P.) and the number of warm temperate species.

  • This study has been conducted to understand the deterioration state and to establish a management plan for the trails of Jeongmaek ridge. To find the extent of the deterioration, researchers investigated twelve physical factors and they examined the states of the trails qualitatively. The results are as follows. The extent of the damages to the trails of the Hannam Geumbuk-Jeongmaek ridge was 78cm in breadth, 6.4cmin depth, 20.8% in slope, the extent of the damages to the trails of the Guembuk-Jeongmaek ridge was 73cm in breadth, 7.3cm in depth, 20.0% in slope. And the extent of the damages to the trails of the Naknam-Jeongmaek ridge was 73cm in breadth, 6.7cm in depth, 17.7% in slope, the extent of the damages to the trails of the Guemnam-Jeongmaek ridge was 79cm in breadth, 6.7cm in depth, 19.7% in slope, which could be interpreted as relatively good. However, it was confirmed that damages to the trails that run through the urban areas and tourist attractions had become worse than in the past. Therefore, in the regions where the number of comers is expected to increase, more detailed monitoring and proactive management is required.

  • The characteristics of forest damage in the Geum-buk Mountains were analyzed by using satellite images and a field survey for landscape conservation purposes. A survey scope was fixed using DEM, and areas of damage in the mountain range were analyzed via ArcMap v. 9.2 using SPOT 5 images, a high resolution satellite image. All damaged areas were reviewed and corrected in a field survey. As a result, 75 roads were found to completely fragment forest patches. Of those roads, 26 have the width under 3m, which means that the fragmentation of the forest by these roads may have a minor effect on forest habitat and its ecosystems, while other roads such as two-lane roads may have broader detrimental influences on the ecosystem. Two thousand eighty-three sections of accounted for a total area of about 5,760.7ha. Orchard areas including chestnut tree plantations were ranked as the largest in the damaged area within the Geum-buk Mountains, followed by public facility areas and grassland areas. This means that man-made land usage has progressed in the area regardless of slope and elevation.

  • The aim of this study was to propose methods to transplant for the ecosystem damage borrow pits. The research site is Junggun-dong Gwangyang-si Jeollanam-do. The total area of the site is approximately $199,026m^2$, but the area damaged by exploitation of soil and rocks is about $84,200m^2$. This signals the transplanting method to solve the problems of ecological destruction. The research will focus on the areas either which are evaluated as damaged or in which the development is inevitable. Therefore, this study will investigate the vegetation structure and their evolution, topological and soil character, and annual ring structure; in the end, the study will propose compensating and restoring options. This study proposed the selection of trees and their planting methods by using the models of the community transplantation(Quercus mongolica trees) and the tree transplantation(Pinus thunbergii trees). The study set out plans that will attempt to restore the Quercus mongolica forests and 89 Quercus mongolica trees of the canopy layer trees, 153 middle layer trees, and 661 shrubs are suitable. The tree transplantation utilized the existing Pinus thunbergii trees. The number of transplantation is 2,648. The total area of the transplantation topsoil is calculated to be $15,353m^3$. These study results must be contributed to reduce a damaged ecosystems and compensated damaged ecosystems for solving the problem of damaged borrow pits.

  • This study targets the city of Paju, Gyeonggi-do, where many challenges are facing ecological assets management due to the increase in recent development. Using the survey data provided by the National Institute of Ecology in Korea, the study analysed the differences in the local residents' perception of local ecological assets. The Q methodology, which is useful for revealing differences in opinions, was applied to classify the narrative groups, which had different points of view in evaluating each asset. Next, the study compared the differences in perceptions of the vulnerability of ecological assets. As a result of the analysis, the city of Paju was divided into two main narrative groups: a 'Nature Conservation Group' and a 'Heritage Conservation Group'. The Nature Conservation Group wanted to prioritize ecologically valuable assets, such as wetlands, brackish zones, and forests. The Heritage Conservation Group preferred preserving ecological assets having a cultural contexts, such as royal tombs, graves, and the surrounding landscape. Evaluating the ecological assets, the two groups identified 23 ecological sites under threat from development among the 25 ecological sites considered. The Nature Conservation Group noted the importance of sites such as the Sannam Wetlands, Gongneungcheon, Gongneungcheon Brackish Zone, and Simhak Mountain. These were considered to be the most vulnerable ecological assets in the city. The study found differences in the perceived values for each ecological asset by residents. The results can serve as useful data for decision-making on ecological asset management in the city of Paju.

  • The destruction of forests requires continuous management due to the risk of disasters such as landslides and landslides. However, existing forest inspection methods are inefficient as they require a lot of manpower and time. Recently, drones are attracting attention as an effective way to construct and utilize spatial information. The size of the drone-related industrial market is rapidly increasing. In this study, we attempted to increase the efficiency of forest investigation utilizing drones. The study area was photographed through the use of drones, and ortho image and DSM were generated through data processing. Study results found that it was possible to calculate the area and the volume for the forest damaged area effectively by employing drones, and suggested the applicability of drones. In the future, it is expected that the method of analyzing the forested area using drones can save manpower and time compared to existing methods.
