Tree species-specific estimates with spacebome high-resolution imagery improve estimation of forest biomass which is needed to predict the long term planning for the sustainable forest management(SFM). This paper is a contribution to develop crown distinguishing coniferous species, Pinus densiflora and Pinus koraiensis, from QuickBird imagery. The proposed feature analysis derived from shape parameters and first and second-order statistical texture features of the same test area were compared for the two species separation and delineation. As expected, initial studies have shown that both formfactor and compactness shape parameters provided the successful differentiating method between the pine species within the compartment for single crown identification from spaceborne high resolution imagery. Another result revealed that the selected texture parameters - the mean, variance, angular second moment(ASM) - in the infrared band image could produce good subset combination of texture features for representing detailed tree crown outline.

Purpose: The aim of this study was to analyze health promotion programs utilizing forests by reviewing regional healthcare program plans in Korea. Methods: We analyzed 227 regional healthcare program plans from 2011 to 2014; seven health promotion programs of the 16 major healthcare programs were prescribed by public health law. Results: Our analysis revealed that only 35 health promotion programs from 29 sites were utilizing forests. Furthermore, of 21 known categories of health promotion programs, only nine incorporated the use of forests. Atopy-asthma healthcare programs were the most common forest health promotion programs, which also included specialized disease management programs (e.g., for atopy prevention and healing, patients with metabolic syndrome or cancer) and specialized mental health management programs (e.g., for addiction or dementia prevention). Others included programs on the development of forest roads or industrial development using forest products. Conclusion: Health programs using forests in Korea are still very limited and primarily comprise atopy-asthma prevention/management, health behavioral change, and mental health programs. This study provided useful information for developing health policies and forest health promotion programs further in Korea.

It is the purpose of this study to address how to manage the urban vegitation using the concept of Urban Forestry which is relatively new to Korea. When we consider the Urban Forestry as a science, We should understand it interdisciplinary subject which includes Forestry, Horticulture, Urban Planning, Landscape Design, Landuse Planning, Business and Humanities. It may say that people and tree are the fundermental components of Urban Forestry. So there are two ways of Urban Forestry Applications-How people care for trees and How trees care for People-. For the application, this study places the focus on the monetary valuation, tree inventory system and traditional forestry application to urban forest management. Pubic Relation, Communication, Ordinances and Budget are also mentioned as a part of Urban Forestry Policy. Monetary valuation of trees and forests is very important for the proper cognition of their real value. So that, they may be equated and weighed against conflicting uses which would cause to be removed or severely mutilated. A tree inventory system which is the essential part of urban tree management can provide the pertinent information about the present condition of urban tree resource. It may aid in reducing the subjectivity of tree management decisions and stimulate them to be made rapidly and can help reduce potential municipal liability by identifying serious problems in time for corrective maintenance practices to be applied for the maximize community benefits and minimimize public nuisances or hazards. Managers can derive the information from the inventory and use it for the various management plan. When we see the structure of tree inventory system as one of the data base management system, Computer is the best equipment for the efficient management plan. Public relation and communication is also important factors to care the people for urban vegetation management. Volunteer management system is a good example for the public relation and communication. Those skills are need to develop for using the priceless, valuable human resources. Budget holds the key to the execution of Urban Forestry. Good inventory can provide for efficient budgeting stratiges through it's scientific analysis for the way of maximum benefits and minimum costs. Forest can be play a vital role for the aesthetic improvement and recreation in the city. This study suggests that the traditional sivicultural application not only improve the quality of scenic beauty and recreation but also the products of timber. So it is more needed to study for strong and scientific application to urban forest management.

This study selected Nakdong River basin zone in Daegu as an example area to conduct landscapetope classification and aesthetic value assessment of landscape according to the classified landscapetope. The main result of this research can be summed up as following. First, the result of landscapetope type classification showed 28 types of landscapetope including complex residential area (AA), natural stream type with copious vegetation (BA), forest type centered on mixed forest of soft and hardwood (EB) along with 129 types of imputed specific landscapetope. The result of the total first assessment using B-VAT showed the first grade 10 types, II grade 4 types, III grade6 types, IV grade 3 types, 5 types for V grade with the lowest value. The second assessment conducted toward the landscapetope types with the grade higher than the average (including III grade) in the result of the first assessment showed that there are 66 spaces for the sites (1a, 1b) with special meaning for aesthetic landscape evaluation. And also, there were 69 spaces for those (2a, 2b, 2c) with meaning for aesthetic landscape evaluation. The design model of this research is largely divided into improvement goal and specific execution plan. First, the improvement goal is divided into 6 categories including conservation area, complementary area, and restoration area, and the specific execution plan is divided into 14 categories including special landscape management area, general landscape management area, conservation of hill areas with optically good condition. A comprehensive master plan was suggested by directly applying the set landscape planning model to the subject place of this research.

The objective of this study was to introduce the current status and development strategy for the environmental restoration of stream side in Japan, and to consider the methodology which could be effectively applied to the environmental restoration of stream side in Korea. 1. We should establish a new paradigm of forest conservation and erosion control which can emphasize the restoration of the stream side ecosystem and reduce soil movement in the areas. Also, in the past, the objective of forest conservation and erosion control was to fix soil by constructing permanent structures. The direction of future forest conservation and erosion control needs to be new forest conservation and erosion control technology to prevent large scale soil movement but allow small scale soil movement to conserve sound ecosystem and biotic habitats. 2. In the past, the goal of forest conservation and erosion control planning was to fix the amount of soil movement by constructing permanent facilities. Forest conservation and erosion control planning in the future needs to change the techniques which could prevent soil movement from large scale of soil disasters, but allow soil movement effectively to a small and middle scale's soil movement. Also, it is considered to change erosion control dams from non passing type to passing type. 3. In the point of ecological conservation aspects, we should evaluate the effects of new forest conservation and erosion control methods which are emphasized on the restoration of the stream side ecosystem. Also, forest conservation and erosion control construction projects for restoring stream and river ecosystem should be planned for perfectly restorating their ecosystems by the way of sustainable maintenance and management. 4. The restoration direction of stream and river ecosystems needs to be restoring the diversity of small geographies such as waterway, shoal and puddles rather than flattening stream bed. And the restoration of the stream side ecosystem should provide continuity of the stream side environment which allows desirable biological habitats, and environmentally sound facilities to harmonize with the environment.

The purpose of this study is to review foreign scenic inventory map for the systematic management of natural scenic resources. Several foreign cases were surveyed and analyzed to apply the scenery inventory map in domestic, such as Visual Resource Management(VRM) from United States Bureau of Land Management, Scenery Management System(SMS) from USDA Forest Service and Visual Landscape Inventory(VLI) from British Columbia Ministry of Forest's, that were already established scenery inventory maps. The results are as follows. First, the characteristic of Korean landscape is quite a different from those of north american's, which is much smaller and more complex in topography and land use. So, it would be difficult to apply foreign system directly and we need more researches to our own system. The multi-stepped landscape unit system is highly recommended. Second, scenic quality could be estimated by the pre-built database, such as land forms, vegetation, hydrology and land uses. Historical and cultural attributes should be complemented. Third, existing scenic integrity could be grasped by scenic damage, landscape alteration caused by human activities and land exfoliation. Also, subjective evaluation method should be supplemented by objective criteria through further detailed studies. Finally, about landscape view conditions, landscape control points should be surveyed and established in advance, and viewing distance, viewing frequency, amount of observers and public interests should be considered.

본 연구에서는 GIS기반의 공간분석과 시뮬레이션기법을 활용하여 산림스카이라인 및 자연경관 훼손을 사전에 검증할 수 있는 친환경적 건축물 높이 예측 프로그램을 개발하고 현지적정성을 검토하였다. 건축물의 높이 예측과 같은 경관평가에 조망점의 위치 등의 선정방법이 큰 영향을 미치는 요인이므로 GIS의 지형분석과 가시권분석을 이용하여 자동조망점을 선정하고, 기존의 조망점 선정방법과의 차이를 통계적으로 검증하였다. One-way ANOVA를 이용하여 분석한 결과 모든 사례지역에서 조망점 선정방법에 따른 평균값의 차이가 없는 것으로 평가되었다. 이에 따라 자동조망점 선정방법으로 프로그램을 개발하고, 필요에 따라 추가 조망점을 선정할 수 있도록 설계하였다. 개발된 프로그램을 이용하여 5개 사례지역에 시뮬레이션을 적용한 결과, 산림경관 및 주변 환경과 조화로운 것으로 나타났다. 다만, 등고선을 기준으로 건축물 높이를 예측하였기 때문에 건축물 값이 다소 낮게 나온 경향이 있으므로 향후연구에서는 나무의 높이와 같은 산림요소에 대한 고려가 필요하다.

국유림은 사유림에 비해 높은 수준의 자본과 기술, 노동력을 투입할 수 있고 상대적으로 집약적인 관리가 가능하다. 따라서 국유림은 장기적인 목재 수요에 대비한 산림자원의 비축기지로서의 역할뿐만 아니라, 사회가 필요로 하는 산림의 다양한 기능을 안정적으로 발휘할 수 있어야 한다. 하지만 현재 국유림은 4영급 이상인 임분이 대부분으로, 영급이 불균형한 상태에서 목재수확기에 도달하고 있다. 따라서 체계적인 경영계획에 의한 목재수확이 이루어지지 않으면 국유림의 다양한 기능의 지속성을 보장하기 어렵다. 본 연구는 국유림의 영급구조를 개선하면서도 경제적·공익적 기능을 지속가능하게 유지하기 위한 국유림의 적정 목재생산량을 추정하는 것을 목표로 하였다. 이를 위해 먼저 국유림 내에서 목재생산에 적합한 지역을 분석하고, 다목적 선형기법을 적용하여 경제적 기능과 공익적 기능을 동시에 고려할 수 있는 산림경영계획모델을 개발하였다. 분석 결과, 국유림 내 목재생산 적합 지역의 면적은 약 488천ha로, 이를 중심으로 목재수확을 적절하게 관리하면 영급분포가 개선되고 공익적 기능도 지속가능하게 유지되는 것으로 나타났다. 향후 100년 동안 국유림에서 생산 가능한 목재량은 연평균 약 200만m³으로, 이는 연간 국산목재 공급량의 44% 수준을 차지하는 것으로 나타났다.
