The purpose of this study is to provide a basic datd for establishing a basic park management plan for Bulamsan Urban Nature Park. This research surveys very closely about the present condition of the natural ecosystem based on the examination and analysis of the present condition. This research suggests development and management methods for environment-friendly park by understanding damages on the ecosystem due to overuse, as well as park facilities and their effects on the surrounding environment, using quantative analysis. The three steps: researching the present condition research, ecosystem evaluation, and park management plan were taken in order. The present condition research is based on the general condition, natural environment, and natural ecosystem data. In the ecosystem evaluation, wildlife habitats evaluation, landscape evaluation, and biotope type research which is a materialized form of the plant ecosystem were excuted based on the present condition research data. In the park management plan step, 1) classified ecosystem and landscae preservation zone, ecosystem protection zone and ecosystem restoration zone as ecosystem and landscape preservation plan, 2) plannings for ecosystem, fine landscape preservation, damaged area restoration and recovery plan were established in order to suggest environment-friendly plan,

The purpose of this study was to carry out a comprehensive assessment of Donjibong Park in Daegu and establish a master plan for green space considering the functional characteristics of the park. For this purpose, green space in the park was assessed based on 13 indicators using three functions. A comprehensive green master plan was then proposed. Green spaces with high scores for the natural-ecological and environmental-control functions were found in the central area of the park, whereas green spaces with low scores were found near the park boundary and paved areas. Green spaces in the southeast were found to have a high score for usage functions due to their proximity to a residential area. In the master plan based on the comprehensive assessment, the plan space was divided into a conservation area, restoration area, buffer area, environmental monitoring area, observatory/trail/facility area, and waterside green space area. Also, concrete plan directions were proposed based on each plan space. These results can be utilized for establishing objective plans in the future construction of new parks.

This study was carried out to understand the variation of bird community by eco-park development of urban stream, Yangjae stream, Seoul, from Jan. 1996 to Dec. 2001. After the development, slight change in the bird community happened; for example, the number of species increased(r²=0.729, p<0.05), but there was not any variation in the total number of birds(r²=0.050, p>0.05). Especially, the number of individuals in herons and ducks rose. We suggest that the change as caused by restoration of low revetment vegetation and artificial pond vegetation in flood plain. However, the number of sandpipers, plovers and wagtails inhabiting on the sands and gravels in stream fell down. It seems that it would be caused by construction of bicycle path on the flood plain. The number of songbirds was tended to go down to 2000, but increased in 2001. The decrease of songbirds might be attributed to irregular removals of bush. We suggested that riparian vegetation restoration and artificial ponds positively affected birds inhabitation, but bicycle path and irregular elimination of a bush negatively affected.

The urban park has important functions as a habitat for wildlife as well as open space of rest and community for people. This study was carried out to find what factors of structure and vegetation of urban parks could affect forest bird species diversity in Cheonan city. The study surveyed bird and vegetation species in 26 urban parks, Cheonan city. A correlation analysis and multiple linear regressions were performed to test whether habitat structure and vegetation were the major correlate with species diversity. The results showed the Dujeong park was the most high bird species diversity (H' = 2.13), and the Dujeong-8 park (H' = 2.02) and the Cheongsa park (H' = 1.73) were considerably higher than the other urban parks. The variables that were strongly correlated with bird species diversity were park area, number of subtree species, canopy of shrub, number of shrub species, shape index, canopy of subtree, canopy of tree, and impervious surface ratio. The regression of bird species diversity against the environmental variables showed that 3 variables of park area, canopy of subtree, and canopy of tree were included in the best model. Model variable selection was broadly similar for the 5 optimal models. It means park area and multi-layer vegetation were the most consistent and significant predictor of bird species diversity, because urban parks were isolated by built-up areas. Especially the subtree coverage that provides shelter and food for forest birds was an important variable. Therefore, to make parks circular-shaped and abundant multi-layer vegetation, which could be a buffer to external disturbances and improve the quality of habitats, may be used to enhance species diversity in creation and management of urban parks.

Urban Green Area has ecologically deteriorated along with quantitative loss, being developed as a dot itself rather than connected to forests and green networks around the park. The present study aims to propose a connected plan on Urban Ecological Network establishment through 'assessment of the connectivity of the entire urban parks' in accordance with distance of forest and river and 'assessment of trends in connection fragmentation of urban parks' in accordance with the past change of forest and river. According to the result of this study, criteria based on previous research was "directly linked type is less than 300m, conceptually linked type is between 300m to 1km, the isolated type is greater than 1km". And the result of 'assessment of the connectivity of the entire urban parks' is analyzed as the rate of park and green network, 41.7% in Suwon, 80.0% in Seongnam, 88.9% in Namyangju on the basis of office and field investigation. Also, according to the result of 'assessment of trends in connection fragmentation of urban parks', consideration for connection to the original forest is insufficient.

Urban parks are important bird habitat in cities. Various studies have evaluated the habitat function of urban parks focused on field surveys. In this study, we performed applicability of NDVI obtained from Landsat 8 OLI image as a factor for spatial planning considered bird diversity. This study was classified with green boundary into three groups using NDVI's value. Environmental variables were calculated by the green area ratio of the surrounding area from 100m to 500m at each groups. The 20 environmental variables such as park area, park shape index, canopy of tree, etc. were derived, the regression analysis was performed as a dependent variable for the bird diversity of urban parks. As a result, the park area and the green area ratio of Group 3, classified high NDVI, within the 100m buffer were adopted as the variables in the regression model. In other words, it was confirmed that as the park becomes larger, the distribution of key green areas within a radius of 100m of the parks becomes higher, the diversity of bird species has increased. It was appropriate to use satellite image, NDVI to analyze species diversity in urban area.

According to the Ministry of Land, Infrastructure, and Transport, the total area of unexecuted urban planning facilities in Korea is about $1,257km^2$, of which 47% is the unexecuted urban green space and forests. In the case of Seoul, the total area of unexecuted urban planning facilities is about $66km^2$, which is 5.24% of the total unexecuted area in the entire country. In Seoul, approximately 88% of the total unexecuted area is urban green space and forests, which is higher than the national rate. About 92% of the unexecuted urban planning facilities are long-term unexecuted urban planning facilities that are more than 10 years old. This study assessed the economic value of potential ecosystem services, focusing on the regulation service, supporting service, and cultural service, for urban green space and forests of unexecuted urban planning facilities in Seoul by using meta-regression analysis. As a result, the value of the regulation service provided by the urban green space and forests in Seoul was about 16.39 billion KRW, the value of the supporting service was about 5.8 billion KRW, and the cultural service value was about 7.78 billion KRW. The total value of ecosystem services is about 33.93 billion KRW. The values of regulation service and cultural service were the highest, and that was attributed to the characteristics of the downtown area. The significance of this study is to evaluate the value of ecosystem services for unexecuted urban planning facilities in Seoul. The results of this study can be used not only in the process of urban planning or policymaking but also land compensation methods applying the concept of an ecosystem service payment system.

In Incheon metropolitan city, the urban open space areas are deficient and it is nearly impossible to obtain newly the land for parks by reason of the risk of the land value, the budgetary deficit and so forth. Therefore, it seems to be urgent to consider how to manage the established urban natural park efficiently to enhance the quality of recreational experiences of the public. The organization for the urban natural parks management is to be completely put in good order, for the objects to manage is changeable as well as diverse and what users need should be full satisfied. The purpose of this study is to investigate the differences of urban natural park's management suggest the improvement and development directions in urban natural park by group(professionals and Users). To do this, data were collected in the typical regions by urban natural park for this study, using the questionnaires. In these urban natural park, the on-site survey was carried out the users of these urban natural park during October in 2004. Also The analysis was done with the valid questionnaires of user's 644 and professional's 146. The questionnaires contained three of categories : openspace types' satisfaction and urban natural park's satisfaction, and management, and park user's socioeconomic characteristics and behaviors. Data collected from respondents were analysized by descriptive statistics, T-test, factor analysis and regression analysis. The results of this study can be summarized as follows; The evaluation of urban natural park management is predicted the operation management. So, one can draw a conclusion that user's needs is likely to be increased correspondingly as urban natural park planning and design, management which meets the overall satisfaction. Using the results of this study, we can make a guideline for a park management program, market positioning, standards and provisions of urban natural park by group.

The purpose of this study is to compare the satisfaction of the urban parks and to classify and assess the environmentally-friendly behaviors in the urban parks. For this purpose, the park user's behaviors and satisfactions were surveyed in 10 parks in Seoul and its suburb area. Parks are divided into 2 types, the walking-distance parks and the metropolitan parks, by time to reach, visit frequency and visit purpose. The park users are generally satisfied with the facilities, but not satisfied with some specific items, such as cultural facilities, accommodations for the handicapped, safety facilities and sports facilities. The environmentally-friendly behaviors are positively assessed in general, but the behavior of the natural experience was negatively assessed. The environmentally-friendly behaviors in the urban parks are classified into 2 factors; the experience factor and the activity factor. The parks are categorized into 3 types by these factors. For type I parks, the experience factor is dominant, but the activity factor is relatively low. For type II parks, the both factors are low and the parks are necessary to improve. And type III parks are positively assessed in the aspect of the environmentally-friendly behaviors, even though some park are necessary to complement.
