  • Studies on landscape ecology have focused on conceptual aspects, while empirical focus for spatial planning has been rarely conducted. This study conducted an empirical analysis to enhance landscape ecological performance of urban developments using landscape ecology. To do so, concrete criteria and standards to analyze structural, functional and variational mechanisms of urban landscape ecology were developed. An integrated landscape ecology assessment model that can be applied to urban development planning was established by combining the criteria. Next, Landscape Ecological Management System (LEMS) was developed to implement an integrated assessment using GIS. To verify the effectiveness of the system, a case study was conducted using LEMS on Byulnae City in the Seoul Metropolitan Area. The LEMS can be useful for urban planners and policy makers in their selection of desirable planning alternatives. Moreover, the LEMS developed in this study can be a useful tool for academia in terms of the implementation of further related studies, and for planning professionals in their environmental impact assessment tasks.

  • Roof greening recently emerged to be an important issue of environmental policies in a city. To cover roofs of buildings with green vegetation gives chances not only to improve urban environmental function but also provides the opportunities of environmental learning and convenience for users in the building. This study aimed to give directions for roof greening plan to designers by acknowledging the relationships between ecological and utilizational effectiveness. 10 sites and 15 variables were adopted to measure the relationships. As a result, no positive correlations was found between them. One of the results in correlation analysis among variables, however, showed that the roof gardens have high utilizational effectiveness only when a green roof was made by focusing on ecological functions in addition to the concepts that will guarantee user's convenience such as accessibility, entrance and exit, facilities for convenience and learning. The results implies that a green roof has to be designed considering multi-functional effects. Correlation between species of vegetation and the number of daily users, average staying hours, and attending level for environment educational programs were not significant. These findings imply that when a green roof has to be take high utilizational effectiveness, both plentiful vegetation species and design concepts for users' convenience are should be considered.

  • Recent landscape changes from human activities, such as agricultural development and urbanisation frequently result in the loss of habitats, the reduction in habitat patch size and an increasing isolation of habitat patches. However, there is little information on woodland changes in agricultural landscapes. Therefore, the aim of this research was to assess spatial characteristics and changes of woodland in an agricultural landscape and how these may have had an impact on ecological process for 33 years. One of the agricultural landscape character units was analysed based on aerial photographs from 1976, 1983, 1994, 2002 and 2009 in Gwangju city. The results indicated that landscape ecological metrics clearly showed that they could be used to monitor changes of woodland ecological conditions during the past 33 years. The results imply that particularly human activities have been leading to the decrease of the mean size of woodland patches and finally result in woodland isolation. These changes may have a negative impact on woodland bird species in the study area. This woodland information can be used to identify the potential and specific needs for setting priorities for conservation planning.

  • This study was conducted to investigate the plant community and to propose ecological planning methods for urban environmental forest on Gaepo neighborhood park, Gangnamgu in Seoul. Thirty-six plots that the size of each plot was 10$\times$10m(100\ulcorner) were set up and the vegetation analysis was carried out. Field survey was executed Apirl, 1994. The actual vegetation was consisted of Poplulus$\times$albaglandulosa community(73.03%), Robinia pseudoacacia community(8.30%) P. $\times$ albaglandulosa-R.pseudoacacia community(1.81%) and environmental forest (15.22%) in the survey site. According to mean importance values of each plot, survey area were divided into ten forest communities. As for the analysis of plant community structure which was classified into ten forest communities, the importance values, ecological diversity, number of species, number of individuals, basal area and crown coverage of urban environmental forest were relatively lower than those of the native community. In urban environmental forest of Gaepo neighborhood park, it showed problems for the planting method. So urban environmental forest should be constructed considering ecological characteristics based on above results.

  • This article statistically analyzed contributive levels of district image based on an effect and a similarity index through the evaluation of citizens and suggested the efficient management system of a city image according to the results. For this study, Busan City was selected as a case city by the preceding literature and was investigated concerning district image and city image through a questionnaire. The new evaluation method for analysis of a city image was presented in this process. The results of this research are as follows: 1. Busan City has a substantial positive and culturally unique image, and each of its districts have other image characteristics. for example, the CBD district has a positive image, and the sea shore district has a busy and prosperous image, but the backward sea shore district has an image of stagnancy. 2. The image of Yeonje-gu has the largest effect on the image of Busan. Next in influence are Jung-gu, Saha-gu, Suyoung-gu, respectively. The effect index is closely connected with the variance of evaluative adjectives. 3. Busanjin-gu and Haeundae-gu have similar images to Busan City. Next in similarity are Nam-gu, Jung-gu, Youngdo-gu, Suyoung-gu, respectively. The similarity index is closely connected with the correlation of evaluative adjectives. Busan City and its districts can establish their image strategies with the above analyzed results. This study is meaningful in that a statistical evaluative method was proposed. With continued follow-up research, this study may serve as a systematic and logical model to improve the urban landscape and image.

  • This research focused on the improved alternatives of the ordinance which practically control the open space in-situ, public open space and landscape construction related to city landscape for the healthy physical and mental life of the city dwellers. The contents of the study are as follows: 1. The special law of Landscape Architecture should be legislated. 2. The portion of landscaping should be changed by up-grading in the Ordinance of Landscape area and planting and the terms of landscape Facilities should include the ecological aspects in it's contents in the law. 3. The administration of local governments should actively lead and support the dwellers to make the roof gardens and the window gardens in the building area of cities or commercial districts which have relatively low rate of green space. 4. Any new construction and restoration of the buildings with preservation of the natural environment and creation of public open space should be given incentive and Set-back space in aesthetic area should have appropriate planting area and facilities in it. 5. Organizing professional landscape evaluation committee and composing evaluation standards are very important because of the contemporary proposition of the establishment of the establishment of ecological space and conservation of urban natural space. Because of the characteristics of Landscape Architecture, the Provisions of landscape Architecture Design and landscape architecture supervision of the specialist should be legislated and the Landscape Architectural Organization should be established within the Government.

  • Purpose: The purpose of this study is to propose a methodology for the urban regeneration by constructing contemporary publicness. Beginning with researching on the theoretical fundamentals about publicness and urban regeneration, it introduces the examples to analyze the spatial characteristics of publicness in the contemporary urban architecture, and finally simulates a model for the formation of space through a real work. Method: The study is partially based on the Executive Urban Project, 'Masterplan to make New Taekrigi : Gosan', which was planned in 2013 to suggest a strategic settlement layout for urban regeneration. Making architectural ideas permeated into the model of urban planing, throughout the design process of initially pursued concepts to the design development stage, we could encounter a new type of formation of urban space, coinciding with the historical, cultural ecological contexts. Result: The expected result of the study intends to enhance the relationship between the formation of public space and urban structure, also ultimately to produce a urban system as 'space generator' to fulfill the social needs and its requirements.
