  • This study analyzed the relationship between NDVI(Normalized Difference Vegetation Index) and urban heat island in three cities: Daegu, Kyungju, and Pohang for understanding the degree of nature conservation concentrating in the transition zone of them. Daegu city is the third city in Korea which has a dense population. Kyungju is a traditional city which has good nature. Pohang is an industrial city which has those of characters of Daegu and Kyungju. Landsat 1M data in May 17, 1997 were used for the analysis of heat island. There were about four theoretical models to estimate the surface temperature from TM data: Two-point linear model, Linear regression model, Quadratic regression model, and Cubic regression model. In this study, Linear regression model had been utilized to analyze the urban heat island. On the resultant images, the transition zone of Daegu was urbanized more extremely than those of other two cities. It is thought that the analysis of relationship between NDVI and surface temperature, used in this study, is regarded as one of effective methodologies for urban-environmental detection from satellite imageries.

  • This study was carried out to investigate the degree of impact from road construction and forest fragmentation after urbanization. And this study was also conducted to compare the urban forest fragmentations of four cities, Taegu, Pohang, Kyungju, and Kumi, in Kyungpook, Korea, with referring the Landsat TM remotely sensed data. Taegu metropolitan city has the largest forest volume of our surveying sites, comparing with three other cities-Kyungju Pohang Kumi city in kyungpook, Korea. The forest has been fragmented during urbanization, the number of forest patch has been increased, therefore, the patch size has been smaller. The forest in Pohang and Kyungju city represented the intermediate aspect between Taegu Metropolitan city and Kumi city, it means forest of the region has been stable condition. Road construction brings to increasing edge habitat area. However, as the core area was decreased, the habitats have been unstable. This result can be a basis on the management of the forest which is the origin of biodiversity. Hereafter, if the research, based on the multi-temporal remote sensing data, is proceeded continuously, the forest fragmentation will be able to be reduced. We will be able to settle urban forest management more practically.

  • This study summarizes the use of satellite data to detect the change of southwestern coastal wetlands in Korea. The images used for this study were two Landsat Thematic Mapper(TM) images (June 12, 1984 & June 2, 1992). TM images were used to classify such different types of wetlands as aquatic bed, nonaquatic bed and other land use in the region. Then it, was possible to a) determine the status of wetlands using image classification products, and b) detect the changes of various types of wetlands influenced by both human and nature. The results from spatiotemporal analysis showed that approximately 120 lad of coastal wetlands were lost from the year of 1984 to 1992. 71 % of the lost wetlands were converted to the reclaimed land. This loss of wetlands has been causing the profound environmental impacts. It has been successfully proved that satellite data are very effective for spatiatemporal change analysis, especially for that of coastal wetlands.

  • We examined a current status of damage in biodiversity and its causing factors in Hasidong Anin coastal dune, Gangneung-si, Gangwon province which is designated as ecological and landscape conservation area. In this study, we found that ecosystem and biodiversity have been primarily damaged by anthropogenic factors such as the construction of surrounding area, military facilities illegally dumped garbage and the expansion of windbreak forest. These factors occur to damage the landscape, ecosystem and biodiversity etc. There is a significant lack of basic data needed for preservation and restoration due to the lack of prior research and value assessment. In order to establish solutions for preservation and restoration, it is critical to collect fundamental data and implement value assessments. Therefore, further studies such as ecosystem services assessment, increasing biodiversity, spatial analysis and monitoring of various items related to coastal dunes are needed.

  • Plants are the basis for sustainable green growth, and the value of existence and importance of trees including landscape Plants can't be emphasized enough. Therefore, they are precious living things thriving in all sorts of public services, and continuous civil complaints for justifiable compensation of landscape Plants are filed. First, the standard formula of planting intervals according to production target specifications is calculated using root-collar caliper and diameter at breast height, and apply (1) standard medium sized trees which have not yet reached commercialization [deciduous tree production goal (R(B) less than 6cm]= (target standard)= [target standard $R(cm){\times}15{\times}0.7$]. (2) In case of commercialization(R6~R10)= [target standard $R(cm){\times}15{\pm}5%$], (3) In case of more than R12= [target standard $R(cm){\times}15{\times}130%$] shall be applied. In case of using diameter at breast height (4) In case of commercialization(B6~B10)= [target standard $B(cm){\times}20{\times}15{\pm}5%$], (5) In case of more than B12= [target standard $B(cm){\times}20{\times}130%$] shall be applied. Second, appraisal methods based on tree classification of compensation for loss are classified according to planted locations. (1) landscape trees within a house=[price of arrival at the site+planting cost], (2) landscape trees in places such as arboretum=[management technology of tress + relocation expenses considering scarcity of the trees (3) landscape trees in a place of loads= [landscape tree production cost + work out added price. In case of producted landscape threes (4) landscape trees ready to be commercialized as sales loss.

  • 우리나라는 국토의 63.7%가 산림으로 국민의 생활지역과 이동 경로 상에서 산림경관으로의 조망기회를 늘 접하는 특성을 가지고 있다. 본 연구는 산림경관관리가 필요한 구역을 세부적으로 구획함으로써 구역별 경관관리 방향을 제시할 목적으로 진행되었다. 산림경관 관리를 필요로 하는 정도를 관리요구도 분석을 통해 파악하고 인위적 경관관리로 생성되는 경관변화의 시각적 영향을 흡수하는 능력을 분석하여 경관관리를 위한 관리구역 구획 과정과 방법을 제시하였다. 산림경관을 우선 관리할 지역을 선별하기 위해 주요 조망점, 통행빈도, 주요 산림경관자원, 도보 및 차량 이동수요가 있는 지역들을 기준으로 하여 산림경관관리 요구도를 분석하였다. 인위적 경관관리가 가능한 지역을 구획하기 위해 대상지의 물리적 경관변화에 대한 수용력인 시각적 흡수능을 분석하였다. 그 결과로 경관관리 요구도 상, 중, 하, 그리고 시각적 흡수능 상, 중, 하 구역을 산림경관 관리지역의 공간상에 표현하였다. 경관관리요구도가 상이고 시각적 흡수능이 상이라면 적극적이고 인위적 경관관리를 할 수 있으며, 일정 수준의 물리적 경관변화를 수용할 수 있는 구역임을 의미한다. 이러한 구획방법을 적용함으로써 산림경관자원과 그 주변의 경관디자인 및 관리를 위한 적절한 수단을 제공할 수 있다는 결과를 얻을 수 있었다.

  • A Visual landscape planning and management system has been introduced and implemented by each ministry so as to solve the problems of visual landscape destruction due to recognition on the value of natural landscape of beautiful territory and various development projects. At present, this system emphasizes the importance of the visual and perceptual aspect of the landscape however, there is a lack of techniques required for comprehensively predicting, evaluating, and managing it. Furthermore, sustainable landscape management after the completion of development projects has been inadequately carried out, as the focus has been only on consultation in the planning process of the development project in institutional performance. To this end, we presented objective and standardized criteria to predict and judge the effects of development projects on landscapes before project implementation. During the implementation of the development project, the influence of the visual landscape becomes accumulated in the construction progress stage. There is a need to identify the main viewpoints and to examine the continuous changes in the landscape-influencing factors, owing to the remarkable influences on the landscape, such as the change in the topography and the change caused by the artificial structure. During the stage of managing the influence on the visual landscape after the completion of the project, the influence on landscape should be monitored by measuring the change in the continuous landscape-influencing factors and determining the extent to which the actual reduction plan has been implemented. These processes should be performed continuously to maintain the quality of the visual landscape. The change in the landscape caused by the development project is shown to cause relatively greater visual damage than other factors composing the landscape owing to the influence of the artificial factors including the structure or the building. This shows that not only detailed examination of the visual impact before the development project but also continuous management is required during and after the development project. For this purpose, we derived eight landscape-influencing factors including form/shape, line, color, texture, scale/volume, height, skyline, and landscape control point. The proposed considering to be of high utilization in that it has a clear target of the landscape influencing factors.

  • The interest on rural ecological landscape has recently grown on the part of policy makers for rural development. While considerable efforts and resources have been invested to preserve and utilize rural landscape, we still lack a systematic means to quantify and evaluate ecosystem service value of the rural landscape and management status. So this study suggests rural ecological landscape management indicator considering ecosystem service value. It consists of 28 criteria and 107 subcategories, which can be applied to rural village. And We have applied ecosystem service value assessment and resident's management status on three villages, Moondang village, Yonggye village, and Sesim village.

  • 본 연구의 목적은 도시경관계획의 효율적 실행수단 확보 차원에서 도시경관 유형화를 위한 기초자료를 구축하는데 있다. 이를 위해 국내 주요 학술지 논문과 경관계획 보고서 중 경관유형과 분류기준을 구체적으로 제시한 기존 연구를 분석하고, 이를 토대로 현행 도시계획의 근간이 되는 용도지역지구제에서 활용 가능한 도시경관 유형화 분류기준을 제시하였다. 연구결과는 다음과 같다. 첫째, 분석과 평가 관점의 경관유형화 방식은 생태학적 접근과 형식미학적 접근에 기반하여 경관요소들의 특성을 분석하며 이를 토대로 경관을 유형화하는 것이 큰 특징이라고 할 수 있다. 둘째, 우리나라 경관계획에서 보여지는 경관유형은 분석을 위한 경관유형과 계획을 위한 경관유형의 혼용에 의해 논리적인 경관유형 분류체계가 확립되지 않았으며, 이로 인해 경관관리대상에 대한 명확한 규정이 없다는 것이다. 이는 결국 경관관리를 위한 경관제어요소와 관리방안에 대한 구체적인 지침 부족으로 연결되고 있다. 본 연구에서는 경관계획 과정상의 효용성을 고려하여 활용 가능한 경관유형 분류기준을 크게 경관구성의 1차적 기준과 2차적 기준으로 제시하였다. 1차적 기준은 지형과 용도지역지구, 경관자원의 성격, 경관요소가 있고 2차적 기준은 경관계획 대상지 외부에서 경관을 구성하는 조망점, 조망점과 경관대상과의 거리, 도시공간의 형태적 특성 등으로 구분할 수 있다. 이를 이용한 도시경관 유형화는 도시 전반에 대한 경관관리가 가능하게 할 것이며, 향후 도시경관유형을 토대로 한 용도지역지구의 운용에 있어 기초자료로 활용될 수 있으리라 판단된다.
