  • 'The Ecological Forest' in Youido Park was intended to be an artificial forest in urban center, following the form of natural forests in central Korea. This study was to investigate the planting plan and the vegetation change of 'the Ecological Forest' and to compare it with natural forests of similar plant composition. The natural forests had slopes between $12^{\circ}$ and $21^{\circ}$, whereas 'the Ecological Forest' had slopes between $2^{\circ}$ and $6^{\circ}$. It was unlikely that the slope condition was adequate to show 'toposequence succession' at 'the Ecological Forest'. The soil bulk density and soil hardness of 'the Ecological Forest' were higher than those of the natural forests. The soil pH of 'the Ecological Forest' was 7.45, which was greater than that of the natural forests. There were some changes in plant composition and amounts 2 years after the construction : the number of conifers was reduced from 383 to 338 ; the number of deciduous trees was reduced from 4717 to 1158. It was because of the young trees dead in the sub-tree layer. The herbaceous species planted were 14 families, 31 species, which increased to 37 families, 93 species after 2 years. In case of horizontal structure of vegetation, trees and shrubs were distributed evenly in the natural forests, whereas 'the Ecological Forest' showed uneven distribution with higher total density. In case of vertical structure of vegetation, the natural forests had distinctive layers with dominant species distributed in each layers. In 'the Ecological Forest', however, dominant species were only in tree layer. The natural forests had greater average tree height, tree density, however, and basal area than 'the Ecological Forest'. The results showed that there were some differences in the structure between 'the Ecological Forest' and natural forests. The management plan should be applied in order that the natural condition be restored in 'the Ecological Forest' by competition between plant species and natural processes.

  • Urban development typically results in many species being confined to small, isolated and degraded habitat fragments. Fragment size and isolation underpin many studies of modified landscape to prevent biodiversity loss. However, habitat characteristics such as vegetation structure and edge effects are less frequently incorporated in planning. The relative influence of biogeographic (e.g. size, isolation) and vegetation parameters on assemblages is poorly understood, but critical for conservation management. In this study, the relative importance of biogeographic and vegetation parameters in explaining the diversity of forest-interior dwelling birds in forest fragments in Chungcheong Province Area. Fragment size and vegetation characteristics were consistently important predictors of bird diversity. Forestinterior bird richness was influenced by fragment size (0.437), wood age (0.332), wood diameter (0.068), and patch shape (-0.079). To preserve bird diversity of Chungcheong Province Area, it is important to consider differing responses of bird diversity to landscape change, move beyond a focus primarily on spatial attributes (size, isolation) to recognize that landscape change also has profound effects on habitat composition and quality. The result is very useful for long-term aspect of biodiversity conservation plan in regional scale.

  • 과거 우리는 경제성장을 위해 집약적으로 도시를 개발해 왔고 이러한 개발정책이 자연생태계에 부정적인 영향을 미쳐왔던 것은 간과할 수 없는 사실이다. 본 연구에서는 이러한 부정적인 영향의 평가를 위해 대구광역도시권을 대상으로 GIS 기법과 경관지수를 이용하여 도시성장에 따른 토지이용과 경관을 구성하는 요소들 상호간의 시 공간적 패턴을 분석하였다. 분석결과 주변지역으로 도시기능의 전이에 따라 도시는 $193.4km^2$가 확산되었으며, 산림은 다른 토지피복패턴으로 $455.6km^2$가 잠식된 것으로 나타났다. 이러한 변화의 과정에서 가장 큰 비중을 차지한 것은 상대적으로 개발여건이 양호한 농경지의 변화임을 알 수 있었다. 또한 산림은 구조적으로 파편화되고 형태는 복잡해졌을 뿐만 아니라 인접패치의 패턴도 다양해진 것으로 나타났다. 이러한 변화는 산림에 대한 외부간섭 또한 증대시켰을 것으로 생각되며, 아울러 생물종의 서식처가 되는 핵심지역을 감소시켜, 그 건전성을 저하시킬 가능성이 있는 것으로 판단된다. 이러한 연구결과는 향후 더욱 광역화되어지는 도시의 개발이 주위 환경구조에 미치는 영향과 상호관계성을 평가하고, 경관생태학적 원리를 고려한 광역도시계획수립의 기초자료로 활용 가능할 것이다.

  • The populations of Pinus densiflora in South Korea were grouped into 4 types; Community of Pinus densiflora-Quercus serrata, Community of Pinus densiflora-Quercus mongolica, Community of Pinus densiflora-Fraxinus sieboldiana & Rhus javanica & Quercus mongolica and Community of Pinus densiflora-Prunus sargentii & Rhododendron mucronulatum. The Shannon diversity index was varied between 0.9171 and 1.5016, while the Similarity index was varied between 43.18 and 72.16. The species of Pinus densiflora are correlated positively significant with Carex humilis var. nana, Quercus serrata and Atractylodes ovata and negatively significant with Aster scaber and Sorbus alnifolia in order. According to the Correlation analysis, the relationship between the distribution of Pinus densiflora populations and the environment factors are closely related with the character of forest soil. Thus types for Pinus densiflora are differed. pH, Ex. K and Ex. Ca of Pinus densiflora populations effect No. of species and H'(shannon index). Canopy open effects No. of Individuals of Pinus densiflora community.

  • Despite it has been mentioned that the successful restoration in landscape level was achieved in the Young-il soil erosion control project, quantitative evaluation of restored plant communities (Alnus firma as introduced species and Pinus thunbergii as native species) was hardly founded. Light availability, litter and woody debris cover, and forest structure and composition were determined for 500 m2 band-quadrat in three forest types. Abiotic factors of Q. serrata stands, as reference forest, and A. firma stands were similar but not for P. thunbergii stands. There were no significant difference on mean stem density (stems ha-1, H = 3.6, p = 0.162), and the mean basal area of each stand had marginal significance (m2 ha-1, H = 5.7, p = 0.058) among stands as total basal area was higher with the order of A. firma (21.4 m2 ha-1), P. thunbergii (19.8 m2 ha-1) and Q. serrata (16.2 m2 ha-1). Restoration of vegetation structure was more effective in fast-growing and N-fixing A. firma, as introduced species plantation. However, result of MRPP, NMS ordination and ISPAN for herbaceous layer, not for tree and shrub species composition, indicated that restoration of ground vegetation was likely influenced highly from local environment. Propagule availability from landscape context such as connectedness to natural vegetation and management practices in restored isolated stands are available explanations for restoration effects and gaps between restored plantations and secondary oak forest.

  • There is little information about appropriate greenspace structures to satisfy aesthetic function in Korea. The purpose of this study was to analyze Korean's aesthetic preferences for greenspace structures concerned with urban tree plantings of an areal type to explore desirable greenspace landscapes. The study considered 5 structural variables of greenspace which were species composition, tree density, tree size, vertical and horizontal structure, and tree layout pattern. A photo-questionnaire was prepared through color simulations of different landscape types for each structural variable. Preference responses of an interval-scale rating from 214 respondents were statistically analyzed between landscape types and between respondent groups. Respondents preferred greenspace landscapes with diverse tree species to single species, higher tree density to lower density, larger trees to many smaller trees, multilayered and grouped plantings to single-layered and sparse plantings, and informal pattern to formal pattern. These preferences tended to be relatively higher for educated specialist and student groups than for other generalist group. Thus, multilayered and dense plantings in natural pattern including larger trees of diverse species, which are similar to ecological plantings, are recommended to increase aesthetic function of greenspace.

  • The purposes of this study were to investigate vegetation structure and present management planning of mountain type green space using the green space changes during the 20 years, actual vegetation, and plant community structure in land area of Inchon, Korea. The actual vegetation area in survey sites was consisted of Quercus acutissima community, Robinia pseudoacacia forest, Pinus rigida forest, Q. mongolica-Pinus rigida community, P. rigida-Q. mongolica community, Q. monogolica community and so on. According to the classification by TWINSPAN, 61 survey plots were divided into 9 groups; Q. mongolica-Alnus japonica-R. pseudoacacia-P. densiflora, R. pseudoacacia-Styrax japonica, P. rigida-R. pseudoacacia-Q. mongolica, R. pseudoacacia-P. rigida-Q. mongolica-A. hirusta, Q. mongolica-P. thunbergii, and prunus sargentii-Zelkova serrata community. From this result, ecological succession trend of vegetation seems to be change from artificial result, ecological succession trend of vegetation seems to be change from artificial planting forest to native plant community which was dominated by Quercus spp.. This study area need to manage for the increase of biodiversity through the restoration of naturalness by ecological management of artificial planting forest and ecological planting of injured green space.

  • 생태계는 인간, 생물 무생물적 환경의 집합체이며, 경관은 생태계가 단위지역에 나타나는 현상이다. 이러한 경관은 다양한 경관요소가 시 공간적으로 나타나는 토지 모자이크이며, 토지이용과 피복 변화는 경관의 구조를 변화시키는 주요 요인이다. 본 연구에서는 경관을 구조적 기능적 측면에서 정량화하는 경관지수와 생태계용역가치(Ecosystem Service Value: ESV)를 이용하여 대구광역도시권의 산림경관의 시 공간적 변화패턴에 관하여 분석하였다. 분석결과, 산림경관의 잠식과 파편화는 택지 및 공업단지조성 등의 대규모 개발행위 보다는 도로 등의 선형적 개발에 의해 발생되었으며, 핵심지역의 상대적 비율은 점진적으로 감소한 것으로 나타났다. 이러한 현상은 생물종의 주요 서식처가 되는 핵심지역을 감소시켜 그 건전성을 저하시킬 가능성이 있을 것으로 판단되었다. 또한 ESV가 산림경관의 면적변화와 밀접한 관계를 가지는 것을 알 수 있었다. 이러한 연구결과들은 향후 생태계를 대상으로 한 개발과 보존의 논리 사이에서 객관적인 평가의 기틀을 마련하고, 광역도시계획 등의 개발계획 수립에서 생태계 가치를 충분히 반영하기 위한 기본적인 척도로 활용 가능할 것이다.

  • The purpose of this study is to suggest the visual landscape plan for Shinan province with ecological landscape resources, which is comprised of more than 1,000 islands. The plan was done by the order of image plan, landscape structure plan and detained landscape plan. The image of Shinan province was elicited as 'nature', 'complexity' and 'connectivity', by the aspects of planning, cognitive and strategic sides. The landscape zones are planned, such as leisure zone, rural & marine ecological zone and marine tourism zone, and the landscape axes are also set, such as marine axis, ecological axis and circular axis. Especially to conserve the ecological resources, some conservation zones are proposed and design guidelines for each landscape type are also provided, which are not commonly included in the urban landscape plan. Consequently, the landscape plan and ecological environmental plan were complementary to each other. In the detailed landscape plan, more specific plans and design guidelines are suggested for coastal scenery, village and forest scenery, historical and cultural landscape management and promotion. To improve the visual landscape in terms of planning and administrative aspects, the visual landscape plan has become increasingly important for the local governments. The establishment of visual landscape plan may hopefully help to make Shinan province more beautiful and attractive. The landscape plan and ecological environment plan should be integrated, and the further discussion and research are necessary.
