  • 과거 50 년 동안 국내 보 설치 수는 매년 증가하여 왔으나, 그 증가비율은 근래 들어 감소하는 추세로, 이는 보 보다는 용수공급능력이 큰 양수장, 저수지 등 타 시설물에 의존하는 것으로 판단 할 수 있다. 더욱이 인구의 도시 집중화에 따른 농경지의 도시화, 경작 방식의 변화에 의한 비닐하우스 단지로의 변화, 시설의 노후화 등으로 매년 $50{\sim}150$개 정도의 보가 폐기되고 있다. 그러나 이렇게 폐기되는 보는 하천에 그대로 존치되어 하천생태통로의 단절, 수질악화, 수변 서식처 악화 등의 문제를 지속적으로 야기 시키고 있다. 실험은 문산천 검전보, 안양천 안양대교보, 기철거된 경안천 무명보에서 자연시료를 채취하여 실행 하였다. 문산천 검전보는 하천환경이 안정되고 양호한 대조구간으로 선정하였다. 안양 대교보는 도심화로 인하여 원기능을 상실하였으며 수차례에 걸친 개수가 이루어졌고 수년전까지만 해도 러브보로 인한 수질정화장치가 있었으나 효능이 약화되어 철거할 계획을 가지고 있는 것으로 알려져 있다. 경안천 무명보는 현재는 완전 철거된 상태이다. 경안천 무명보는 기 철거된 보의 대조구간으 로 선정하였다. 보 상류의 수질 오염도가 높은 것은 정체구역에 의한 용존산소 부족과 오염저니에 의한 것으로 판단되므로, 각각의 대상보의 퇴적물 오염도를 조사하였다. 각각의 조사 지점은 검전보의 경우, 만장교를 최상류 지점으로, 검전보 상/하류, 광탄교를 최하류 지점으로 선정하여, 총 4 지점에서 채취했으며, 안양대교보의 경우 최상류지점, 보 상/하류 지점으로 총 3지점, 무명보의 경우 보 상/하류로 총 2 지점에서 채취했으며, 실험은 $\ulcorner$Soil Method$\lrcorner$에 준하여, 각각 입도분포, 함수율, 강열감량, COD, T-N, T-P 등을 시행하였다. 문산천 검전보 퇴적물 오염도 조사 결과, 강열감량, COD, T-N, T-P 항목에서 보 상류가 보 하류에 비해 높게 나타났으며, 각각 하류에 비해 상류가 30.76%, 16.69%, 73.13%, 18.91% 더 높게 나타났다. 안양대교보 퇴적물 조사 결과, 검전보와 마찬가지로, 강열감량, COD, T-N, T-P 항목에서 보 상류가 보 하류에 비해 33.33%, 9.23%, 24.78%, 18.56% 높게 나타났다. 기 철거된 무명보의 경우, 무명보 상류, 무명보 하류 2개 지점을 채취하였으며, 강열감량, COD, T-N 항목에서 보 상류가 보 하류에 비해 18.75%, 412.6%, 25.75% 높게 나타났다. 퇴적물 조사 결과, 강열감량, COD, T-N 항목에서 검전보, 안양대교보, 무명보 모두 보 상류의 오염도가 높게 나타났으며, 무명보를 제외한 검전보, 안양대교보는 T-P 항목에서도 보 상류의 오염도가 높게 나타나, 보 상류의 퇴적물 오염농도가 심화된 것으로 나타났다. 그러나 기철거된 무명보의 경우, 강열감량, COD, T-N, 항목에서 보 상류가 높게 나타났으나, 철거되지 않은 검전보나 안양대교보에 비해 그 차이가 크지 않은 것으로 나타났다.

  • Gardening activities, plant raising, and general flowerbeds the public makes today can be found in the original form of cottage gardens in the United Kingdom. A cottage garden is a popular garden style of modern Britain, implying unique Englishness including ethnic sense and vernacular. In addition, the purpose of this study is to consider the modern movement in the United Kingdom in the past 200 years and read Englishness of cottage gardens through style differentiation and background of occurrence of cottage gardens appearing in this process. Therefore, this study is summarized as follows. First, a view of nature of the Englishman loving freedom and landscape acts as a key part of patriotism and is connected to the preservation of idyllic England. For this ideal of the Englishman of the country, idyllic British characteristics are found in various literatures and artistic fruits; cottage gardens, that is a form of new garden, were made with invigoration of supply and collection of plants. Second, an early form of cottage gardens was the domestic garden, in which there is a vegetable garden by middle-class move to a suburb according to urbanization, but evolved into a form of garden having both artistry and regionality, vernacular, and ecological characteristics with various situations of modern society(handicraft promotion movement, preservation of remains, and ancient building restoration movement). Wild gardens occurring in this process are a type of garden realizing wild fields and forests in the United Kingdom;they have made a big impact on many garden designers up to now. Cottage gardens, reflecting a variety of Englishness, is a subject of city planning and flower shows and is a culture symbolizing the United Kingdom.

  • In this study, we investigated the spatial variation in land use and topographic effects on water quality at the Geum river watershed in South Korea, using the ordinary least squares(OLS) and geographically weighted regression (GWR) models. Understanding the complex interactions between land use, slope, elevation, and water quality is essential for water pollution control and watershed management. We monitored four water quality indicators -total phosphorus, total nitrogen, biochemical oxygen demand, and dissolved oxygen levels - across three land use types (urban, agricultural, and forested) and two topographic features (elevation and mean slope). Results from GWR modeling revealed that land use and topography did not affect water quality consistently through space, but instead exhibited substantial spatial non-stationarity. The GWR model performed better than the OLS model as it produced a higher adjusted $R^2$ value. Spatial variation in interactions among variables could be visualized by mapping $R^2$ values from the GWR model at fine spatial resolution. Using the GWR model, we were able to identify local pollution sources, determine habitat status, and recommend appropriate land-use planning policies for watershed management.

  • The Demilitarized Zone (DMZ) stretches two kilometers north and south from the Military Demarcation Line (MDL) of South and North Korea. This area was established as a weapons-free buffer zone when an armistice agreement was signed in 1953. However, there have been several very high-tension military standoffss over the past 65 years. On the South Korean side, civilian access to the Civilian Control Line (CCL) and beyond to the north has been restricted, and natural heritage has been well maintained. Natural heritage is defined as living things, their habitat and non-living things of the ecosystem which deserve to be protected. Research shows that a variety of flora and fauna, their habitat, marshes and geographical structures are found across the DMZ region. Although the DMZ region has not been such a good place for habitat conservation, we can say that this area may be the best location for restoration in terms of its variety of ecosystems and considerable land size. Restoration of course depends on future plans and management policies. This area, including the DMZ and the well-protected north of the CCL, will be the best habitat for endangered species of wild fauna and flora if we classify the various habitat types and create a habitat map. In doing this project, we need to include the estuary of the Han River and the lagoon (brackish water lake) of the East Sea coast. In addition, we must establish long-term plans for conservation and sustainable use and do international scientific research across the DMZ region in collaboration with scientists of South and North Korea and international experts. Mutual cooperation between the two Koreas for investigation and conservation efforts is paramount.

  • In this study, we revealed the location environment and community structural characteristics after extensively investigating Korea's warm-temperate island areas and categorizing vegetation through TWINSPAN analysis. Based on it, this study aims to suggest the direction of the vegetation restoration plan for warm-temperate forests by deriving a restoration strategy for each vegetation type. The vegetation types were clearly divided into eight types, and communities I through IV were good evergreen broad-leaved forests dominated by Machilus thunbergii and Castanopsis sieboldii. On the other hand, communities V through VIII were Pinus thunbergii forest, deciduous broad-leaved forest, and artificial forest, and retrogressive succession vegetation in the warm-temperate areas. The environmental factors derived from the DCA analysis were altitude (average temperature of the coldest month) and distance from the coastline (salt tolerance). The distribution pattern of warm-temperate forests has been categorized into M. thunbergii, C. sieboldii and Cyclobalanopsis spp. forest types according to the two environmental factors. It is reasonable to apply the three vegetation types as restoration target vegetation considering the location environment of the restoration target site. In communities V through VIII, P. thunbergiiand deciduous broad-leaved formed a canopy layer, and evergreen broad-leaved species with strong seed expansion frequently appeared in the ground layer, raising the possibility of vegetation succession as evergreen broad-leaved forests. The devastated land where forests have disappeared in the island areas is narrow, but vegetation such as P. thunbergii and deciduous broad-leaved forests, which have become a retrogressive succession, forms a large area. The restoration strategy of renewing this area into evergreen, broad-leaved forests should be more effective in realizing carbon neutrality and promoting biodiversity.

  • Selection of the plant material for planting to reduce fine dust should comprehensively consider the visual characteristics, such as the shape and texture of the plant leaves and form of bark, which affect the adsorption function of the plant. However, previous studies on reduction of fine dust through plants have focused on the absorption function rather than the adsorption function of plants and on foliage plants, which are indoor plants, rather than the outdoor plants. In particular, the criterion for selection of fine dust reduction species is not specific, so research on the selection criteria for plant materials for fine dust reduction in urban areas is needed. The purpose of this study is to identify the priorities of eight indicators that affect the fine dust reduction by using the fuzzy multi-criteria decision-making model (MCDM) and establish the tree selection criteria for the urban planting to reduce fine dust. For the purpose, we conducted a questionnaire survey of those who majored in fine dust-related academic fields and those with experience of researching fine dust. A result of the survey showed that the area of leaf and the tree species received the highest score as the factors that affect the fine dust reduction. They were followed by the surface roughness of leaves, tree height, growth rate, complexity of leaves, edge shape of leaves, and bark feature in that order. When selecting the species that have leaves with the coarse surface, it is better to select the trees with wooly, glossy, and waxy layers on the leaves. When considering the shape of the leaves, it is better to select the two-type or three-type leaves and palm-shaped leaves than the single-type leaves and to select the serrated leaves than the smooth edged leaves to increase the surface area for adsorbing fine dust in the air on the surface of the leaves. When considering the characteristics of the bark, it is better to select trees that have cork layers or show or are likely to show the bark loosening or cracks than to select those with lenticel or patterned barks. This study is significant in that it presents the priorities of the selection criteria of plant material based on the visual characteristics that affect the adsorption of fine dust for the planning of planting to reduce fine dust in the urban area. The results of this study can be used as basic data for the selection of trees for plantation planning in the urban area.

  • The present study was undertaken to classify and describe the spring naturalized plant communities in old-Andong city by the methodology of the ZM school of phytosociology. As a result, the vegetation was classified into the six communities and two subcommunities: A. Bromus tectorum community A-a. Bromus japonicus subcommunity, A-b. Melica onoei subcommunity; B. Poa pratensis community; C. Rumex crispus community; D. Oenothera lamarckiana community; E. Ambrosia artemisiifolia var. eiatior community; F. Rumex conglomeratus community. The total taxa of the naturalized plant communities consisted of 31 families, 86 genera, 114 species and 13 varieties. Of which the taxa of the naturalized plant species consisted of 8 families, 21 genera, 25 species and 1 variety. The result of Bray-Curtis ordination revealed that the plots suveyed were arranged according largely to the vegetation units of' the communities. Also the interspecific affinity was examined by an analysis of interspecific association and the main component species in the communities were divided into two groups. The naturalized rate was higher in the communitise affected by strong human impacts, while was lower in the communities affected relatively less by human impacts. On the other hand the seasonal changes of the communities and the naturalized rate between the spring and the autumn were investigated. Many naturalized communities present in Spring were replaced by the other native ruderal communitues in the Autumn. The naturalized rate based on the dominance was largely decreased over from the spring to the Autumn.

  • In urban areas, the impermeable area continues to increase due to urbanization, which interferes with the surface penetrating and infiltrating of rainwater, causing most rainwater runoff to the surface, deepening the distortion of water circulation. Distortion of water circulation affects not only flood disasters caused by rainfall and runoff, but also various aspects such as dry stream phenomenon, deterioration of water quality, and destruction of ecosystem balance, and the Ministry of Environment strongly recommends the use of Low Impact development (LID) techniques. In order to apply the LID technique, it is necessary to set a rainwater management target to handle the increase in outflow after the development of the target site, and the current standard sets the rainwater management target using the 10-year daily rainfall. In this study, the difference from the current standards was analyzed through statistical analysis and classification of independent rainfall ideas using inter-event time definition (IETD) in setting the target amount of rainwater management to improve water circulation. Using 30-year rainfall data from 1991 to 2020, methods such as autocorrelation coefficient (AC) analysis, variation coefficient (VC) analysis, and annual average number of rainfall event (NRE) analysis were applied, and IETD was selected according to the target rainfall period. The more samples the population had, the more IETD tended to increase. In addition, by analyzing the duration and time distribution of independent rainfall according to the IETD, a plan was proposed to calculate the standard design rainfall according to the rainwater management target amount. Therefore, it is expected that it will be possible to set an improved rainwater management target amount if sufficient samples of independent rainfall ideas are used through the selection of IETD as in this study.
