  • This study is the application of a choice experiment to assess Mekong Delta urban households' preferences and motivations for ecosystem conservation in the U Minh forest. The study applied a choice modeling approach to estimate the economic values of the proposed ecosystem conservation program in the U Minh forest by accessing urban consumer preferences and their willingness to pay for the project. Discrete choice experimental data was collected from 450 residents in the cities of the Vietnamese Mekong Delta. The multinomial logit model was employed to identify consumer's stated preferences for the environmental and sustainability attributes of the conservation project. The results showed that Mekong Delta urban residents paid much attention to the proposed project to protect and develop the U Minh forest. In addition, the results showed that higher education, income, and knowledge of the U Minh forest revealed a higher likelihood of selecting the project, while the older residents would select the status quo more than the younger ones. The study also proved that the effect of participation had a strong impact on the willingness to pay for the project. The findings could be useful for policymakers to take action to raise resident's awareness and willingness to pay for the U Minh forest project.

  • 본 연구는 서울과 경기도 지역 도시숲의 수자원 공급 생태계서비스와 기후완화 생태계서비스를 평가하였다. 생태계서비스를 자연기능기반 서비스, 산림의 자연기능과 인구분포를 고려한 생태계서비스, 산림의 자연기능과 수혜자 분포를 고려한 생태계서비스의 세 가지 서비스로 구분하여 평가하고, 이후 기후변화가 생태계서비스에 미치는 영향을 평가하였다. 평가 결과, 토지피복과 토양 등 자연조건을 반영한 도시림의 수자원 공급서비스의 경우, 경기도가 서울보다 높은 서비스를 제공하는 것으로 나타났으며, 지역별 인구분포를 추가적으로 반영한 서비스 평가에서는 인구가 많은 곳에서 서비스가 높게 나타나는 양상을 보였다. 그러나 도시림의 수자원 수혜자 분포를 추가로 반영한 수자원 공급 생태계서비스 평가 결과는 인구분포를 반영한 서비스 평가 결과와 공간적으로 다르게 나타났다. 같은 수원함양 기능을 가진 지역이라도 인구분포나 물 사용 수혜자의 분포가 많은 지역일수록 높은 서비스 결과가 나타났다. 또한 기후변화가 수자원 공급 생태계에 서비스에 미치는 영향을 평가한 결과, 기후변화에 따른 수자원 공급 서비스는 평균적으로 26%정도 줄어들어 전반적인 수자원 공급 생태계서비스가 낮아지는 경향을 보였다. 기후완화부문의 경우, 산림으로부터 가까운 거리에 있을수록 높은 온도저감 효과가 나타나 산림주변지역에서 높은 기후완화서비스가 나타났으며, 기후 완화 서비스의 수혜자 인구를 고려한 생태계서비스 평가에서는 수혜인구의 밀도가 높은 서울 도심지역에서 높은 서비스가 나타났다. 기후변화에 따른 산림 생장량 변화를 반영하여 산림의 기후완화 생태계서비스의 변화를 평가한 결과, 평균적으로 약 33%의 서비스 감소가 나타났다. 본 연구의 결과는 도시림을 관리하기 위해서 산림청에서 제시하고 있는 공급기능기반의 6가지(자연환경보전, 산지재해방지, 목재생산, 산림휴양, 생활환경보전, 수원함양) 기능구분 외에 서비스를 수혜하는 수요자 기반의 기능 및 서비스가 평가의 필요성을 제시한다. 이는 기존의 산림의 공급기능기반의 평가에서 간과할 수 있는, 자연기능은 낮지만 수혜를 받는 시민들이 많아 높은 서비스 가치를 갖는 산림을 재평가하고 올바른 관리 계획을 수립하는데 기여할 수 있을 것으로 판단된다.

  • This work aims to establish the landscape ecological countermeasures to improve the sustainability of urban mountain forest and to enrich the biodiversity in twenty mountains of the Seoul Metropolitan City. Landscape ecological analysis was conducted based upon various criteria, such as area and elevation of mountains, flora, naturalized plants, vegetation, forest types, mountain trails, and public facilities. Various measures were suggested for the better maintenances of floristic diversity, introduced plants, vegetation and forest types of urban mountain forests. Sustainable recommendations for land use adminstration were developed for the preparations of a climate change-adapted urban mountain forests, as well as rational managements of ecosystem, walking trails, and public facilities within mountain forest. Rich and diverse natural vegetation as well as high floristic diversity were reported at mountains with higher elevations, larger area size, and rich landscape diversity. Mountains with low elevation, small size with easy public access, however, might require an urgent action to decrease the burdens by anthropogenic disturbances and urban development.

  • This study is to suggest the technique of ecological park to compatible mountain ecosystem near the urban in Woomyeonsan Urban Nature Park. It was proposed to differential technique from established ecological park focused on changing the cognition of nature, wetland ecosystem protection and restoration, and studying by served sound leisure program(nature observation and experience, etc.), in compatible mountain and urban forest near the Urban. Firstly, to achieve this aim, it was carried out delicated research and analysis that were the angle of inclination, trail, fauna, actual vegetation, bird and insect, and then to selected nature trail course and analysis capability through it.. In the basic concept and plan, firstly to make park aid mark and foundation mark, and then to establish the detail programs, nature observation program, management and organization program. This site where valley and mountain coexist was highly capable but whole site was very steep, so usable area is very narrow. To make Woomyeonsan nature ecological park escape from the established wetland type, ecological park and the park of event have to use nature material and introduce visitor. To establish it as the Nature Culture observation park and reflect on forest, valley of Woomyeonsan was divided into three display places; Nature ecosystem Zone, Meditation Zone, Nature Culture experience Zone and Nature Culture observation Center. For satisfying with ecological park aid mark and foundation mark, it was proposed to settle management plan for volunteer control and organization composition.

  • The purpose of this study was to analyze biotope types of urban land-use patterns. Forest areas were considered according to vegetation type and potential for succession. Urban ecosystem structure was analyzed according to land use, land coverage, vegetation structure (actual vegetation, diameter at breast height, layer structure, and revetment). As a results of the classification, the biotopes were divided into 71 types according to the urban ecosystem structure. In the case of the Hanam province, the biotopes were divided into 51 types: 26 forest types; 5 swampy and grass land types; 3 farm land types; 3 types of planted land, and 8 types of urbanization.

  • Urban green spaces supply ecosystem services (ESs), which are consumed by city residents and generate demand, to improve air quality. It is important to determine supply and demand for ESs and reduce the gap for efficient management. This study proposed a method to use the concept of supply and demand for ESs in the decision-making process for urban planning or management. PM10 concentrations were converted to weight for demand assessment on PM10 reduction, and PM10 absorption capacity of all green spaces including the forests, and that of urban green spaces excluding forests, was calculated for each supply assessment. The differences in the calculated supply and demand were analyzed to derive the mismatched regions in Suwon. As a result, regions with big forested areas showed sufficient supply, indicating that the degree of mismatch among administrative neighborhoods (dong) varied greatly depending on whether they had a forest. An analysis of only urban green spaces showed that all neighborhoods lacked supply. Forests with high PM10 absorption capacity had a great effect, but urban green spaces can be considered a key element in reducing PM10 in daily life. Considering the mismatch of supply and demand, spatial distribution, and population distribution, it is possible to prioritize the supply of urban green spaces to reduce PM10 and, furthermore, support decision making for priority zones subject to forest conservation and designation and cancellation of green spaces, which gives significance to this study.

  • The purpose of this study was to propose an ecological management plan by the comprehensive analysis of biotope structures on Namsan Urban Natural Park in Seoul. Classified by actual vegetation, structure of layer and vegetation damage, biotope structures were composed of forest area, compact management area, herb area, cultivated area and non-ecology(urban) area. Succession had seened to stop in the Native forest. Artifical forest was divided into two types. The first, upper layer, was too dense to accommodate lower layer plants, the other case was the appearance of Quercus spp. and the first stage plants of succession following the declination of the upper layer plants. The soil pH of Nam-san Urban Park was 4.21∼4.51, which meant the soil was becoming acid. As the result of acidity, leaching of available nutrition(K/sup +/, NH₄/sup +/, Ca/sup ++/ etc.) was immediately influenced by the natural ecosystem, influence of acid rain was disturbed to becoming organic matter which was use to plants. In the case of a biotope structure management plan, the urban area was prohibited to spread outside. Cultivated and herb area was regenerated to natural forest. In the forest area, the compact management area was maintained with its present condition, and then it is desirable to make a preservation area and to plant shrubs. Planted Pinus densiflora Community was needed to eliminate competitive species of canopy layer, and plant shrubs. Management of deciduous broad-leaved Comm. was maintained in its present conditionand it is desirable to raise the diversity of the understory and shrub layer. The management of the artifical forest seems to be suitable for Q. spp. community. The care of naturalized plants prevents the expansion and restores the structure of wild plants. The soil management was a marked restoration soil ecosystem in order to prevent soil acid and drying.

  • Short rotation woody crops belonging to the genera Populus L., Salix L., Pinus L., and Eucalyptus L'Her. have provided broad economic and ecological benefits throughout the world, including afforestation and reforestation along urban to rural gradients. Within the genus Populus, cottonwoods, poplars, aspens, and their hybrids (hereafter referred to as poplars) have been shown to exhibit favorable genotype ${\times}$ environment interactions, especially in the face of changing climates. Similar growth responses have been reported for Pinus, especially with white pine (Pinus strobus L.) in the North Central United States. This has led to current research priorities focused on ecosystem services for both genera. The Millennium Ecosystem Assessment (2005) defines cultural, supporting, provisioning, and regulating ecosystem services. The overarching objective of this paper was to synthesize information about the potential of poplars to provide multiple ecosystem services when grown at sites with varying soil and climate conditions across landscape gradients from urban to rural areas. Specific objectives included: 1) providing background of the United States Forest Service and its Research and Development branch, 2) integrating knowledge of current poplar breeding and development with biomass provisioning and carbon regulating ecosystem services as they relate to changing climates in the North Central United States, and 3) providing a case study illustrating this integration through comparisons of poplar with white pine. Our results were evaluated in the context of climate change mitigation, with specific focus on selection of favorable genotypes for sequestering atmospheric carbon and reducing fossil fuel carbon emissions.

  • This study was carried out to create a master plan for an urban eco-forest, including concepts of forest restoration, forest management, and nature education. The concept of an urban eco-forest is different from the original eco-forest, which pursues the conservation of native species in their habitats, using the resources of special plants, etc. The study site was a hill (128m) managed as an urban natural park. Citizens have usually used the park for fitness purposes, as a place for outdoor exercise early mornings on weekdays and holidays. The result of a questionnaire survey showed that the users knew about the eco-forest, and they wanted to participate in the nature education programs. The flora and actual vegetation were weak about conservation of native species on the site. The framework of the plan consisted of development of the ecological forest and forest restoration, and allowed for recreation and the experience of nature, according to the concepts of the urban eco-forest. The landscape was divided into the experience zone of biodiversity, the experience zone of a valley ecosystem, the forest restoration zone, and the recreation and experience zone in nature. Based on this framework, detailed programs and theme areas were planned, as were forest restoration models and planting plans.
