Accessibility of urban green space, as an important index of evaluating the service level of urban green space, not only shows the resident's access to green space, but also reflects the environment quality of urban living. Since the quantity, area and space distribution of the patches in urban green space directly affect the function of urban green space and the quality of urban environment, the research on the accessibility of urban green space holds great significance to improve the service of urban green space and the living environment quality. Based on GIS software, this research uses the road network and the population distribution data of Nanjing's city proper to conduct quantitative analysis of the accessibility of park green space and the convenience for residents to travel under different forms of transportation. After the case analysis, the author tests the application of road network in studying the accessibility of urban park green space and proposes a GIS-based method to study the accessibility and the rational layout of urban green space.

Urban park and green space provide various functions. Among the functions, human benefit and increase of biodiversity are known to be important. Therefore, it is important to consider human and biotic aspect in the process of selecting suitable site for park and green space. However, there is insufficient research on both aspects. In this study, we used green network to analyze human and biotic aspect to select suitable site for park and green space in Seongnam City in Korea. To analyze the green network, we used accessibility for human aspect and used dispersal distance and habitat size for biotic aspect. We conducted least-cost path modelling using movement cost. In case of biotic aspect, GFS (generic focal species) is used to estimate habitat size and dispersal distance. To find out suitable site for park and green space, we used an overlay analysis method. As the result, old residential areas are shown have insufficient green network which needs park and green space. Furthermore, the green network for biotic aspect is insufficient in old residential areas comapred to green network for human aspect. The result of this study could contribute in planning of park and green space to maximize their functions.

본 연구는 공원녹지체계를 광의의 개념으로서 오픈스페이스적으로 접근하는 것이라고 설정하고, 그 방법론을 모색하고 실증적으로 대전광역시 도심지역에 적용하였으며, 그 적용 결과에 기초하여 대전광역시 오픈스페이스 네트워크 구축방안을 제시하였다. 연구방법으로 첫째, 대전광역시 구도심을 대상으로 오픈스페이스 네트워크의 적용 가능성을 검토하며, 둘째, 사례지역의 결과를 토대로 대전광역시의 오픈스페이스 유형별 네트워크를 분석하고, 이를 종합함으로써 대전광역시 오픈스페이스네트워크를 구상토록 하였다. 연구결과로서, 활동오픈스페이스 요소인 관공서 및 업무시설들은 자체적으로 또는 건물 전면부에 공개공지가 조성되어 있고, 이들 전면부 공개공지는 보행로(그레이 오픈스페이스)와 연결되어 있으며, 이들 보행로는 결과적으로 대규모 공원이나 하천(그린 및 블루 오픈스페이스)으로 연결되어, 통합하여 하나의 공간체계를 형성한다고 할 수 있다. 따라서 도시 중심부에는 그동안 공원녹지체계의 기본적 요소라고 할 수 있는 공원과 녹지가 상대적으로 적기 때문에, 공원녹지의 추가적 확보가 이루어져야 공원녹지체계의 개선이 진행된다고 볼 수 있다. 도심부에 새로운 공원녹지의 신규조성은 매우 어렵다는 전제하에 도심부에 마치 실핏줄처럼 분포하고 있는 오픈스페이스 네트워크체계로 접근할 경우, 도심부에 보다 건강한 휴식공간체계가 형성될 것이다.

Nowadays the parks in Shanghai tend to develop towards two directions. Small and medimn parks are being gradually transformed from closed management to open management, while large ones emphasize their nature of theme and nature of functions. Simultaneously, the number of large and open public green spaces has been significantly increased. Although the public green space does not adopt the management pattern for parks, there is almost no difference between public green space and ordinary parks so far as the functions and scales are concerned. Due to the fact that there is no obvious boundary between a public park and a public green space, this paper raises a suggestion to coordinate continuously their management and functions so that the distribution of and the connection between the urban green spaces can be more rational and more definite and a sound green network can be formed. Starting from the viewpoint of emphasizing accessibility to green spaces and enhancing the angle of linking green spaces, we aim at transforming a park system to a multifunctional green system, extending the effects and service radius of large green spaces, and strengthening the internal connections with the surrounding areas so that a high-quality green space can be formed with the connection of the green space network.

Present green space planning of Korea pay little attention to biodiversity conservation in urban areas. The quality of urban wildlife habitat has been deteriorated severely due to fragmentation and isolation of urban open spaces. The application of ecological corridors to urban green space planning and management can greatly enhance the bird habitat of Seoul. The objectives of this study were to evaluate bird habitat potential of existing urban parks of Seoul, and to investigate methods to develop ecological corridors for wild birds. This study consists of three parts. The first part is to construct bird species/habitat relationship model. The second part is to evaluate 207 urban parks of Seoul with the model. Based on the relative potential for bird habitat, urban parks of Seoul can be classified into cores, nodes, and points of the network. Outcomes of this part can also be used to enhance the quality of bird habitats by identifying limits or weakness of existing green spaces for bird habitat. The final part is to develop three green network plans; north-south network, the Han river network, and a district network for Kangnam-Gu.

The rapid urbanization in developing countries is accelerating both the depletion and fragmentation of urban green space, despite the known positive effects of green spaces on the environmental conditions in cities and the quality of life of residents. Consequently, there is a need for practical tools that can support the development of networks of urban green spaces. This article presents a study that used a GIS-based least cost path (LCP) analysis to identify the best alternative for developing an urban green space network in the coastal city of Jakarta, Indonesia, which was based on the evaluation of topography and land use characteristics. Pair-wise analysis was used to reduce the sensitivity in the LCP model. The results showed that the coastal wetlands in the northern part of Jakarta and the agricultural fields in the suburban areas of Jakarta play an important role in connecting the green space network. On the other hand, some green spaces in the central part of Jakarta could not be connected by the LCP model. The method used in this study can serve as a tool to support the identification of networks of potential urban green spaces. It can also provide useful information for sustainable urban landscape planning and management in urban ecosystems. However, the inclusion of socio-economic criteria would further improve the model.

본 연구는 1975년부터 2006년까지 서울시 녹지 연결망의 시계열 변화를 그래프 이론을 적용하여 공간의 다중규모(multi-scale)에서 정량적으로 분석하였다. 분석대상 시기 동안, 서울시 녹지 연결망의 변화가 크게 나타난 공간 규모는 녹지 간 1,000 ~ 1,600 m 거리였다. 1990년 이후 난개발로 단편화되고 훼손되었던 녹지들과 연결망이 점차 복원되고 있음을 확인할 수 있었다. 2006년 개별 녹지의 연결망 분석을 통해, 핵심 녹지와 징검다리 녹지의 두 가지 유형의 녹지 연결망 분포를 확인하였다. 서울시 녹지 분포는 연결성 중요도 지수와 상관관계가 높아서, 남쪽과 북쪽의 가장자리에 핵심 녹지가 분포하고 동쪽, 서쪽, 중앙에 매개 중심성이 높은 징검다리 녹지가 분포함을 정량적으로 표현할 수 있었다. 따라서 서울시 녹지 연결망은 그래프 이론을 적용하여 연결 중심성, 매개 중심성, 연결 중요도 지수 등으로 정량적으로 표현될 수 있다.

The purpose of this paper is to classify zones disrupting green spaces in city and to evaluate of their grades. The results are as follows; L There were 158 green spaces in Dalsu-gu. The 158 green spaces were classified 4 patterns and minutely classified into 9 types. The area of the 'nature park' type was turned out to be $70.1\%$ of the total area of green spaces in Dalsu-gu, then the type was considered as a important part of the green-network in Dalsu-gu. The 9 types such as 'nature park', 'river', 'neighborhood park' and so on were analysed with ecological indexes. 2. Based on the ecological indexes of 'ratio of the green space', 'features of the surrounding matrix' and 'travel distance of the wildlives' , zones disrupting green spaces were ranging widely and re-divided to 236 sectors. 3. The analysis results for classifying the grades were that grade I appeared over industrial complex and housing complex widely. On the other side, grade II and III appeared around or between nature park and neighboring park Consequently, it was necessary to consider the grade and make zones disrupting green spaces into green space for improving green network.

The purpose of this study is to classify urban green space, to assess an imbalance by an administrative district (Dong), and to establish the management zone of urban green spaces for the construction of an environmental city in Changwon. The spatial data of 1:5,000 digital maps, park data in Changwon, land cover by the Ministry of Environment, and IKONOS satellite images from 2003 were used for this analysis. The assessment of the imbalance of urban green spaces was analyzed with the Lorenz curve and Gini's coefficient. The establishment of the management zone was performed by network analysis of GIS. The results of this study are as follows: the urban green spaces were classified as a park green space, a natural green space, and a riparian green space. According to the results of assessment of the imbalance of green spaces, Gini's coefficient was analyzed at higher than 0.4. Thus, the spatial imbalance of urban green spaces in Changwon was evident. The management zones to solve the imbalance were established: "rich zone", "fair zone", "poor zone" and "broken zone". Therefore, the rich and fair zones which have rich green spaces must maintain the good conditions through analysis of the green network and a survey of civic attitudes. The poor and broken zones which have poor green spaces must improve quality and quantity through creation of additional green spaces, construction of an eco-industrial park, and utilization of children's parks and pocket parks.
