  • This study modified and applied the ecological network(Indicator 2) from the City Biodiversity Index(CBI) to be tailored to Korea. It is calculated by utilizing a biotope map and a land cover map. The ecological network of Gyeryong-Si was 13,713,703(33.8%) with the biotope map and 17,686,966(37.9%) with the land cover map. The result of the biotope map was lower than the land cover map. The ecological network of Goyang-Si was 4,961,922(4.9%) with the biotope map and 4,383,207(3.7%) with the land cover map. The result of the land cover map was lower than the biotope map. As a main result of the research, an error was discovered in which, when calculating the ecological network, the types of the military unit facilities were distinguished into a special area on the biotope map and into an urbanization promotion area and a forest area on the land cover map. In the case of a middle-classified, land cover map, the land use in the surroundings of the forest area was not subdivided. An error in the development area expressed as a forest green was discovered. When selecting the natural elements, too, regarding the types of artificially-created rivers, artificial ponds, and artificial grasslands, etc. on a biotope map, the exclusions were necessary. Regarding the natural, bare ground on a land cover map, there was a need to calculate by including the natural elements. It was judged that, in the future, the ecological network in the unit of the entire nation can be analyzed roughly by utilizing a land cover map. It was judged that, in a city having a biotope map, the calculation of the ecological network utilizing a map of the present situation of the urban ecology will be a more accurate diagnosis of the present situation.

  • This work was designed for the Green Fund Aid 2004 of Korea Forest Service. It won the prize and has been constructed. We can have an opportunity to play a leading role in improving partnership with participation of local communities, promoting environmental education, and enhancing the environmental quality by constructing biotops in urban areas where energy flow in the ecosystem is not balanced. This design includes 'citizen participation process' and 'local community partnership' that is expected to promote local community participation in the process of design. This work suggests that biotope construction with citizen involvement and community partnership plays an important role not only in design items but also in the revitalization of local community. This sort of design process could not be fully achieved without cooperation with stakeholders - environmental specialists, local authorities, relevant societies, schools, teachers, parents of students.

  • In Suwon, the overall hygiene of the city is threatened by the emergence of the rook(Corvus fugilegus) in the city. Rooks began to appear in November of 2016 and has continued to appear from November to March every year. In order to eradicate or to prepare an alternative habitat for rooks, this study aimed to identify the preferred habitat and specific environmental variables. Therefore, in this work, we aim to understand the predicted distribution of rooks in Suwon City with citizen science and through MaxENT, the most widely utilized habitat modeling using citizen science to analyze the preferred habitat of harmful tides appearing in urban areas. In this study, seven environmental variables were chosen: biotope group complex, building floor, vegetation, euclidean distance from farmland, euclidean distance from streetlamp, and euclidean distance from pole and DEM. Among the estimated models, after the time period of sunrise (08:00~18:00) the contribution percentage were as following: euclidean distance from arable land(39.2%), DEM(25.5%), euclidean distance from streetlamp(22.3%), euclidean distance from pole(7.1%), biotope group complex(4.9%), building floor(1%), vegetation(0%). In the time period after sunset(18:00~08:00) the contribution percentage were as following: biotope group complex(437.4%), euclidean distance from pole(26.8%), DEM(13.4%), euclidean distance from streetlamp(11.8%), euclidean distance from farmland(7.9%), building floor(1.4%), vegetation(1.3%).

  • Assessment institution of urban ecosystem is divided into ‘Urban Planning Act’and ‘Environmental Management Act’in Korea. The assessment institution of urban planning is divided into ‘Standard of land development approval’and ‘Environmental assessment of urban planning’. The institution of environmental management is divided into ‘Environmental impact assessment’and ‘Advance environmental assessment’. Assessment institution of urban ecosystem is progressed very slowly, because of development oriented policy. And so there are many problems that objective assessment method is not invented except ‘Degree of growing tree number per unit area’and ‘Degree of human disturbance of vegetation’, and insufficiency of conservation measures or post evaluation, etc. Activation of assessment institution of urban ecosystem is necessary followed countermeasures in Korea. (1) Development of objective assessment method for urban ecosystem as biotope map, (2) Appointment of censer-vation zone or consideration of damage for high value in conservation, (3) Parallel establishment of development and ecosystem conservation plan, and enforcing post evaluation

  • This study was carried out to investigate the current urban forest network and future plan of forest framework using nearest features program where stepping stones within 5km from the core forest were selected in the program. We found several conclusions as follows: First, we found that cities in inland area including Daegu, Dajeon and Gwangju have quite different types of forest network with comparing to the cities nearby coastline including Busan, Incheon and Ulsan. The cities in inland area have large mountain patch around each city. However they have small and lower number of island forests within their urban area. Otherwise, cities nearby coastline have more forest patches than in the cities in inland area, and Busan and Incheon especially have strong forest network using various size of forest patches. Second, Daegu and Daejeon have much smaller forest patches distributed in each urban area. So additional forest patches should be added to have highly strong forest network within urban area. Third, Ulsan and Gwangju have most stepping-stone forests close to the large mountain patches in suburban area, which are not able to connect to the forest patches in the central area of each city So additional forest patches are needed to be added in the central area of each city for reinforcing the effect of stepping stone in the central area. Though there should be an addition approach except for forest size and its isolation to construct the ecological network in an urban area, this indices can be a good method to check an environmental and ecological status in an urban area.

  • The purpose of this study is to verify the effectiveness of the biotope model in applying and developing Korean urban forests. We found that there are 17 biotope assessment indicators, including forest layer structure, site conditions, ratio of broad-leaved trees, species richness, etc. In terms of correlation analysis between indicators, the stand ages and the period of space formation have the highest relativity(coefficient 0.684). On the other hand, indicators that have negative relativity are layer structure and risk, with a coefficient of -0.412. Ten models were developed for the multiple regression analysis. 10 variables(site conditions(X2), ratio of broad-leaved trees(X3) and so forth except layer structure(X1), species richness(X4)) were found to have a 95% significance level The results from comparing the regression model and adding-up estimation matrix, the most accurate one was Model 3, which has a 91.7% out of the 10 models. However more monitoring will be needed to improve the accuracy of models for the Korean urban forests in future.

  • The purpose of this case study is to provide the basic knowledge and the rationale for establishing the professional personnel position of Landscape Architecture(LA) in local Government of Korea o the basis of the characteristics and adoption system of professional personnel organization in comparison with the cases of Japan, the United States of America, and Germany. I have analyzed the case of Chonju City, Chollabuk-Do, recruited professional personnel of LA by using informal career position, to justify the needs and the division of professional Landscaping works of the city and to figure out drawbacks of the current adoption system of professional personnel in South Korea. In have found the following results that 1) City Mayor in Korean local Governments do not have the proper authorizing rights of recruiting the special personnels for performing urban policy, which is under controls of the Official Appointment Regulations, 2) because of no official position status for specialist in the fields of LA, the Chonju City had been recruited them as Urban Planner status through an informal process, 3) the section of Park and Urban Forestry was established under the control of Department of Culture and multimedia Industry, 4) the fields of specialized works of LA are defined as the work of ecopolis design and planning, biotope networking, ecological bridge and ecological restorations, and 5) the professional positions for LA should be established in Official Appointment Regulation for the urgent needs of local Government sin South Korea.
