  • This study aims to examine the distinctions in evaluation index items between overseas and domestic ecological area-related systems, derive analytical indicators, and assess recently completed apartment complexes before and after the implementation of overall ecological area ratios. The objective is to analyse variances in the application of ecological area characteristics, categorizing them into ecological area analysis indicators and presenting their implications. The spatial scope covers completed apartment complexes in both metropolitan and non-metropolitan areas. Thirty-six completed apartment complexes were selected for analysis, and basic ecological area data were compiled. Subsequently, the data was utilized to categorize three analysis indicators-ecological area ratio, ecological area diversity, and ecological area connectivity-by metropolitan and non-metropolitan areas, as well as by type of apartment complex (sale housing versus rental housing) and size (large-scale, medium-scale, and small-scale). Results of the analysis indicate higher ecological area ratios and greater diversity in ecological area spatial types in metropolitan areas compared to non-metropolitan areas, and in pre-sale housing complexes compared to rental housing complexes. Mediumand large-scale apartment complexes exhibit higher ecological area ratios, with ecological area diversity being more pronounced. Ecological area connectivity reveals more numerous and varied connection points and types in metropolitan areas than in non-metropolitan areas. Implications of this study suggest that large-scale development should prioritize securing ecological area ratios and diversity in apartment complexes. Enhancing biodiversity necessitates establishing connections within and beyond the ecological area network of the complex. Future research should focus on linking the ecological area network within the complex.

  • The purpose of this study is to improve Biotope Area Ratio(BAR) systems used in the various fields. Recently, there has been increasing demand in urban agriculture as well as more residents cultivating farms on a small scale. However, there are few measures in terms of architecture and urban planning to respond to this trend. In this sense, this research is effective as it can respond to these demands by using BAR systems. Yet, the environmental indexes are not enough since BAR systems only take account of vegetation. Therefore, this study proposes an alternative way that includes the capacity factor of the plant growth by expanding the existing BAR systems. Thus, the study analyzes the complementary possibility of BAR systems, including elements of daylight, planting interval, area and soil depth with existing BAR elements.

  • The purpose of the study is to analyze the regional effectiveness of wall-plantings by applying a biotope area ratio when wall-plantings are constructed in high density areas. For this, this study required a sample of the wall-planting's regional plan. Therefore, types of wall-planting were determined and applied to a sample site. Four types of wall-plantings were developed by formative features and functional features. Type "A" had simple and functional features, Type "B" had both mixed and functional features, Type "C" had both simple and landscape features and Type "D" had mixed and landscape features. Jung-gu District in Seoul was chosen as the sample site. Total investigations were performed three times for three months from June to August, 2011. Total green-able walls were located in 498 places with a total length of 8,449m and gross vertical area of $23,754.90m^2$. The classification results of total green-able walls by the four types were Type "A" at $1,936.65m^2$, Type "B" at $5,875.30m^2$, Type "C" at $12,487.85m^2$ and Type "D" at $3,455.10m^2$. This study analyzed how all facade areas of the green-able walls impacted the biotope area ratio at the site. First, the biotope area ratio regarding all the zones in Jung-gu District was defined as the gross biotope area ratio while the biotope area ratio regarding all of the artificial zones was defined as the net biotope area ratio. In the case of the gross biotope area ratio, 17.97% is current ration with a projected increase to 0.10% after wall-planting. In the case of the net biotope area ratio, 4.73% is the current ration with a projected increase to 0.11% after wall-planting. This 0.11% is about 2.28% of 4.73%. This study looks at all wall-plantings that have been constructed throughout a high density area to observe their impact on the improvement of ecological function therein. With consideration of the landscape value of the facade, the regional effectiveness of wall-planting is expected to increase even more.

  • North Korea has been in ecologically deficit state since 1966, despite of lack of energy and food resources. Trends of the Biocapacity (BC), the Ecological Footprint (EF), and the Ecological Deficit (ED) of North Korea were shown and five factors influencing on the Overshoot Rate (OSR) which is the ratio of the BC and the EF in North Korea was analyzed in this study. The five factors consist of two factors affecting to the EF and three factors affecting to the BC in North Korea. Two of the five factors are affecting to the EF those are population, the EF per capita (EFPC) which indicates the individual environmental consumption intensity, and three are affecting to the BC those are the land area, the yield factor, and the value multiplying the equivalence factor and the intertemporal yield factor. The EF has contributed more than the BC to the OSR. From 1966 to mid-1990s, the EFPC was the most contributing factor at about 60%, and after mid-1990s, population at about 40~60%. Contribution ratio of land area and the yield factor have increased after mid-1990s up to 15% and 18%, respectively. The BC of cropland which has decreased due to a decrease in productivity. In order to reduce the ED of North Korea, improvement of productivity of cropland and restoration of forest. Forest area has decreased significantly since 1990 in NK. And ways to solve the food shortage problem which influences on decrease of both productivity of cropland and forest area.

  • 잎의 생태 계절학적 변화는 지상의 탄소/질소 순환에 큰 영향을 미칠 뿐 아니라 토양 수분, 증발산과 같은 물 순환에 중요한 인자로 작용한다. 이를 모의하기 위하여 많은 지면-생태 생태모형들이 개발되어져 왔지만, 자연현상을 충분히 이해하지 못함으로 인하여 모델 결과값과 실제 관측 값에 차이가 발생된다. 이러한 한계점을 해결하기 위하여 실제 모형과 관측되어진 자료를 실시간으로 융합하는 자료동화 기법이 개발되어져 모델들의 오차를 줄여주거나, 실제 모델의 파라미터들을 보정하는데 사용되어지고 있다. 본 연구에서는 지상기후모형인 Community Land Model(CLM)을 기반으로 하여 2003년부터 2010년까지 동아시아지역을 대상으로 연구를 진행하였다. 지면-대기-해양 모델로부터 발생되어진 40개의 앙상블 기상자료를 이용하여 도출된 잎면적 지수와 Moderate Resolution Imaging Spectroradiometer(MODIS) 잎면적 지수를 실시간으로 융합하는 앙상블 칼만 필터기법을 이용하여 잎면적지수 자료동화가 생태 생태 수문에 미치는 영향을 알아보았다. 특히 잎면적 지수 자료동화가 동아시아 지역의 가뭄에 미치는 영향을 평가하기 위하여 1~3 m 의 토양수분의 변화를 이용하여 가뭄을 정의하였다. 이러한 토양수분 가뭄을 시 공간적으로 나타내어 동아시아지역의 가뭄의 기간, 심도 와 같은 가뭄을 특성을 이해하여 보고자 하였으며, 잎면적 지수 자료동화가 가뭄에 미치는 영향을 알아보았다.

  • This study focused on improving the Biotope Area Ratio, which has existing availability as a legal and institutional method for the architectural and urban fields to respond rapidly to recently growing demands for urban agriculture. The existing Biotope Area Ratio indicators only considers the depth and permeability of soil among a range of conditions for plant growth; they can be used for landscaping plants management but have difficulties in dealing with plants that are the major factors in urban agriculture. This study aimed to verify this hypothesis and suggest a direction of improvement in the Biotope Area Ratio. The study discovered that the management of plant growth only using the Biotope Area Ratio indicators has limitations.
