  • The purpose of this study was to compare and apply quantitative indices for analyzing the total green space in an urban area, targeting Guro-Gu, Seoul. The indices were classified in terms of plane, solid and urban planning. The park area per person as an index of the park green's total volume was $2.34m^2$. This clearly shows the deficiency of park area. However, it did not reflect actual green space, since undesignated forests, rivers and green spaces in the city were excluded. Green coverage area per person in terms of plane was $18.85m^2$ and was useful as an index of actual urban planting, focusing on expansion of the green space. However, the conception of total volume of park green had limitation to be recognized as a unit of area. The number of trees and green area volume per person in terms of solid was 4.1 trees and $35.8m^2$, respectively. This enabled reflection on qualitative improvement plans such as increasing the volume of trees for the high density of developed areas.

  • This study investigated Chinese Laws on the kind of urban green spaces and the legal requirements for the green spaces of urban habitat and analyzed the specificities of them intending to provide basic data to suggest bringing in or not the relevant Chinese Laws to Korea. This study can be summarized as follows: First, the concept of Chinese urban green spaces(g.s.) classified by 5 kinds(park g.s., production g.s., protection g.s., attachment g.s., the others g.s.) placed the park and green spaces in the same category unlike the Korean urban green spaces that only distinguishes between park and green spaces. The Chinese Urban Park is classified by 4 kinds(composite park, community park, special park, linear park) at the 'Standard for urban green spaces classification' which is below in rank of the legal system. Second, in case of calculation for green spaces ratio of urban green spaces in China, the green rooftop landscaping area should not be included as a green spaces area except the rooftop of a basement or semi basement building to which residents have easy access. The green spaces requirements and compulsory secure ratio by 3 habitat kinds(habitat, small habit, minimum habitat) of when to act as a residential plan is regulated. Third, the green spaces system is obligated to establish at habitat green spaces plan and is specified to conserve and improve existing trees and green spaces. The green spaces ratio on reconstruction for old habitat is relaxed to be lower than for new habitat and a gradient of green spaces is peculiarly clarified. The details and requirements for establishment and the minimum area intending for each classes of the central green spaces(habitat park, children park, minimum habitat's green spaces) are regulated. Especially at a garden style of minimum habitat's green spaces, intervals between the south and north houses and a compulsory security for green spaces area classifying into two groups(closing type green spaces and open type green spaces) by a middle-rise or high-rise building are clarified. System of calculation for green spaces area is presented at a special regulation. Fourth, a general index(area/person) of public green spaces within habitat to achieve by 3 habitat kinds is determined, in this case, the index on reconstruction for a deterioration zone can be relaxed to be lower to the extent of a specified quantity. A location and scale, minimum width and minimum area per place of public green spaces are regulated. A space plot principle including adjacent to a road, greening area ratio against total area, security of open space and the shadow line boundary of sunshine are also regulated to intend for public green spaces. Fifth, the minimum horizontal distance between the underground cables and the surrounding greening trees are regulated as the considerable items for green spaces when setting up the underground cables. The principle to establish green spaces within public service facilities is regulated according to the kind of service contents. It shall be examined in order to import or not the special regulations that only exist in Chinese Laws but not in Korean Laws. The result of this study will contribute to gain the domestic landscape architect's' sympathy of the research related to Chinese urban green spaces laws requiring immediate attention and will be a good chance to advance into the internationalization of Korean Landscape Architectural Laws.

  • This study was carried out to investigate the effect of green area in apartment complexes to variation of temperature. The inside temperature of each site was estimated by analyzing Landsat ETM+ image data. The factors on variation of temperature were landcover type, building density, and Normalised Difference Vegetation Index(NDVI). The results of correlation between inside temperature of apartment complex and land cover type showed that the green area ratio had negative(-) correlation and impermeable pavement ratio had positive(+) correlation. Building-to-land ratio was not significant with inside temperature. A coefficient of correlation between the temperature value and the value of permeable pavement ratio added up green area ratio was higher than a coefficient of correlation between the temperature value and the value of permeable pavement ratio added up impermeable pavement ratio. Thus we may define that permeable pavement area decrease urban temperature with green area in apartment complex. Floor area ratio had no significant correlation with inside temperature. Inside temperature was decreased as the NDVI was increased. To establish the temperature distribution model in a development apartment complex, As the result of regression analysis between inside temperature as dependent variable and permeable pave ratio+green area ratio, green area ratio, building-to-land ratio and NDIT as independent variables, only permeable pavement ratio added up green area ratio of the independent variables was accepted fur regression equation in both two seasons and adjusted coefficient of determination was 41.4 on September, 2000 and 40.4 on June,2001.

  • One of the major factors which increase urban temperature is roads. This paper is aimed to investigate the effect of urban roadside vegetation on the road surface temperature. For this, surface temperature was measured at 18 spots using the thermal imaging camera in terms of road components including use of roadside land use, roadway, sidewalk, roadside vegetation and vegetation median barrier. The size of the roadside vegetation and related urban road characteristics were also measured. In terms of the effect of roadside vegetation on a decrease in road surface temperature, the roadside land use as a green area or open space was the highest, followed by the size of vegetation median barrier and the size of roadside vegetation. Besides road surroundings, an increase in the green zone such as roadside vegetation and median strip vegetation has a significant impact on lowering road surface temperature. Therefore, a good solution for reducing urban heat island effects would be to increase the area of roadside vegetation and green areas along roads.

  • This study analyzed urban greenspace area and vegetation structure by land use types for Kangnam-gu and Junglang-gu in Seoul different in income and building construction date. The study districts had a similar areal distribution of land use types. Residential lands accounted for about 32~37% of total area, natural lands, 19~22%, commercial and industrial lands(including transportation), 13~18%, and institutional lands, 13~17%. Greenspace covered only 20~30% of urban residential and commercial area in which human activities of living concentrate. Canopy stocking level in urban lands (all land uses except natural and agrecultural lands) was about 39% for Kangnam-gu and 50% for Junglang-gu, showing tree planting potential slightly higher in Kangnam-gu than in Junglang-gu. Woody plant cover was approximately 13%, and tree density was 3 trees/100m$^{2}$ forurban lands in both districts. The tree-age structure was largely characterized by young, growing tree population, and species diversity within a diameter class decreases as the diameter classes get larger. Urban lands of both districts had quite a similar species composition of woody plants (similarity indez of 0.70). Income and bulding construction date did not result in significant diference between the two districts in vegetation structure for urban lands. Some strategies were ezplored to solve problems found in the present greenspace structures. They included increase of biomass and greenspace area through minimization of unnecessary impervious surfaces, creation of multilayered and multiaged vegetation structures, and avoidance of intensive tree pruning and relocation of above ground utility lines.

  • The purpose of this study was to propose the change of green area and green structure according to the change of the Floor Area Ratio(FAR) of apartment complex. The survey site was selected two each of apartment complex after due consider three type that is, the FAR below 100%, the FAR below 250% and the FAR over 250%. Green rate is 40.23~44.23%, green width is 3~15m, green volume is 1.06~1.71㎥/$m^2$, planting density of cannopy layer is 0.04~0.06tree/$m^2$, planting density of understory layer is 0.06~0.20tree/$m^2$ in case of Hwagok 2nd Jugong apartment(FAR 99%) and Gaepo Jugong apartment(FAR 73%) constructed in the 1970~1980. Green rate is 24.16~26.16%, green width is 3~7m, green volume is 0.84~1.54㎥/$m^2$, planting density of cannopy layer is 0.18~0.31tree/$m^2$, planting density of understory layer is 0.15~0.35tree/$m^2$ in case of Deungchon Jugong aparment(FAR 226%) and Gaehwa apartment(FAR240%) construsted in the mid-1990's. Green rate is 23.47~25.53%, green width is 2~6m, green volume is 1.06~2.12㎥/$m^2$, planting density of cannopy layer is 0.25tree/$m^2$, planting density of understory layer is 0.22~0.37tree/$m^2$ in case of Hanbo Guam apartment(FAR 269%) and Donga 3rd apartment(FAR 376%) constructed in the last-1990's. As the results of analysis of green structure according to changes of the Floor Area Ratio(FAR), the greater the FAR, the higher the rate of green area. The green volume and planted density is low without the change of the FAR and planted structure was simple-layer structure composed of alien woody species.

  • This study aims to analyze the spatial accessibilities to urban greens considering the catchment areas of urban parks to improve those areas with lower spatial accessibility in the neighborhood units. Nam-gu in Daegu was selected as the study area. In the results of the analysis of 16 existing parks, Daemyung6-dong and Daemyung5-dong had high ratios of green service area to administrative district, with values of 94.4% and 92.3%, respectively. Low ratios of green service area(vulnerable area of green service) were recorded in Icheondong(1.6%) and Daemyung10-dong(24.1%). However, the ratio of Icheondong may increase by 88.6%, when the 12 unexecuted urban parks are established. The ratio of Daemyung10-dong can also increase up to 40.1% by establishing green spaces in public institutions such as government offices and schools. This study suggests possibilities to improve the spatial accessibilities to urban parks and indicates the policies required for enhancing the even distribution of green spaces.

  • Urban parks play the role of providing leisure spaces for people in their everyday life along with serving ecological functions in the city. Although urban parks aim to satisfy the needs of users visiting the park, most urban parks are currently uniformly created and maintained without considering the environmental characteristics based on the needs of users. This study thus analyzed parks that underwent modifications in line with the revised Park Act in 2005. There were 45 parks whose types were legally changed, of which 21 were changed from children's parks to small parks, and 19 were changed to utilize and highlight the themes such as cultural parks and historical parks. Among the parks whose types have changed, the ratio of amenities in cultural and historic parks has increased, while the facility area in small parks has decreased and the green area has increased in its place. As a result of analyzing the changes to the park facility area, it was confirmed that increasing park amenities has a positive effect in pursuing revitalization of use through park maintenance, but has a negative consequence of significantly decreasing green area. It is necessary to reorganize the park type classification system to reflect the park environment and prepare guidelines for a new installation standard by park type to expand the net function of parks in cities and maintain the sustainable ecological environment. Through in-depth discussions on the facilities of park types, it is anticipated that innovative and multilateral research could be conducted to prepare improvement measures tailored to the guidelines of urban park types in years to come.
