  • A forest watershed management project was introduced in 2004 to develop ecologically sound forest watersheds. It includes landslide prevention and erosion control, water resource management, landscape development, and forest resource management. However, it has been managed fragmentarily and inefficiently, far from the original intents. This study investigated current status, problems, and improvement measures of the project. Literature reviews were conducted on forest watershed management in Korea and other countries, and surveys were conducted on 201 erosion control experts. When introduced, the forest watershed management project was well planned and implemented as intended. It later turned to focus only on disaster prevention such as erosion control dams and stream conservation measures. The survey results showed that a majority (89% and 86%) of surveyees wanted increases in the project period and budget. They also responded that conflicts with local residents (51%) and determining project locations (32%) were the most difficult tasks when implementing the projects, and only 36% kept project records. To plan and implement the projects as intended, the following suggestions should be considered: (1) establishment of a solid legal foundation and improvement of the erosion control practices law; (2) increase in the project period (from 1 to 2 - 3 years) and budget; (3) development of a manual for project site selection and guidelines; (4) monitoring and systematic information management; and (5) development of spatial analysis tools for watershed analysis and management.

  • 본 연구는 100년 전 제작된 1918년 제주도 정밀 고지도를 바탕으로 당시 제주도의 노거수에 대한 기록정보를 확인하고 복원하여 기초정보를 구축하는데 목적이 있다. 고지도 분석을 위해 ArcGIS를 활용하여 대표지점 선정을 통한 좌표계 및 배율 일치작업을 수행하였다. 고지도에서 표기한 독립수 좌표정보를 점 추출법을 활용하여 디지타이징하였으며, 지도에서의 범례 형태 및 상대적 크기를 바탕으로 속성정보를 추출하였다. 100년 전의 고지도를 바탕으로 제주에 분포했던 노거수 현황을 파악하였으며, 당시 노거수의 특성을 분석하였다. 또한 현재 보호되고 있는 노거수 정보를 바탕으로 과거와 현재 노거수의 특성 및 제주 경관과 식생에서의 노거수 기여 가능성을 분석하였다. 연구결과 100년 전 제주도에는 1,013개체의 노거수가 섬 전역에 분포하고 있었다. 목재이용에 집약적이었던 당시 시대적 상황에도 불구하고 마을과 인접한 저지대에서도 노거수는 보호의 대상이 되었으며, 제주 고유 경관의 대표적인 구성요소로 존재해 왔다. 현재 잔존하고 있는 노거수는 총 159그루로 파악되었다. 과거와 마찬가지로 저지대 인가 주변에서 분포가 확인되고 있으며, 개체수의 감소는 섬 전역에서 확인된다. 개체 감소의 주요 요인으로는 제한수명 도달, 자연적 교란(태풍, 병해충, 건조 등)과 함께 인위적 교란(대규모 개발 사업, 목재이용 등)이 주도적으로 영향을 미친 것으로 판단된다. 그러나 405개체에 이르는 많은 수의 개체는 제주 식생의 복원과정에서 중요 종급원으로 기여하여 현재의 숲을 형성하는데 주도적인 역할을 감당한 것으로 판단된다.

  • A large scale of riverside rearrangement has been recently done in the major rivers in Korea. So inundation possibility in agricultural area closed by these rivers has been higher than the possibility a few years ago. However, land use in this area has not been adjusted to a change of this situation near the rivers. Therefore, when typhoon or heavy rain is happened on this area, it can cause a large damage in agricultural area. This study analyzed inundation potentiality in agricultural area at Ibang-myeon, Changnyeong-gun, Kyeongnam-province, Korea by using the logistic regression model and the piecewise regression model. The first thing we did was to transfer the inundation area per elevation to the accumulated inundation area per elevation. This accumulated inundation area per elevation as an distribution function could be described by the logistic regression model(LRM), and piecewise regression model(PRM) could make it much more accurate to analyze the inundation area per elevation. As a result, the regression models derived from LRM and PRM showed $R^2$ over 0.950. The models derived from LRM and PRM in Ibang-myeon noted that frequently inundated area(FIA) was shown up to 12.12m in elevation, and potentially inundated area(PIA) was shown up to 14.60m in elevation. In FIA, regular agricultural activity would be impossible. And It would be not easy to continue the regular agricultural activity in PIA. So, this land should be rearranged to be used for a buffer zone for ecosystem protection, landscape conservation and things like that in riverside.

  • The purpose of the present study was to compare the long-term management objectives, policy objectives, implementation plans, and detailed plans of four provincial parks established in 2013 using various analysis frameworks. Through this, the study aimed to identify the characteristics of the management plan and extract the implementation plan important to each park by analyzing the priorities in the detailed plan. The long-term management objectives of most parks were to maintain recreational functions by utilizing all the resources of the park, rather than merely preserving the ecosystem. From an ecological perspective, information on major plants and legal protection species are included for most parks, and geological and topographic features considered a major resource. For sustainable forests, it is important to induce the dispersion of concentrated use space. Efficient management systems are distinctively differentiated among the parks. For regional revitalization, the management of programs to link provincial parks and their surrounding areas has become most important. From an ecological perspective, priorities differed for the parks according to their ecological characteristics. For sustainable forests, Moaksan Provincial Park prioritized the visitor reservation system related to the overall park, while the other three parks prioritized alleviating the concentrated use of specific areas. From an efficient management perspective, Daedunsan Provincial Park prioritized aspects related to the cableway. Maisan Provincial Park prioritized inducing the linkage between the use of natural and cultural resources, and Seonunsan Provincial Park prioritized establishing an ecological and cultural commentary operating system. For the base-type leisure activity space, Moaksan Provincial Park prioritized the systematic management and operation of the pilgrimage route, Maisan Provincial Park the connection between the Maisan geography and residents' income, and Seonunsan Provincial Park providing a space for ecological education.

  • 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.

  • Rural amenity is regarded as a breakthrough that can revitalize the rural communities. The demand for rural amenity development is also increasing since the urban people have growing incomes and leisure time. This study was implemented to survey the needs and application directions of rural amenity database. The survey questionnaires were collected from various related groups including industry, universities, administration and research institute. Two kinds of analysis of variance (ANOVA) were carried out in order to prioritize the building rural amenity resource map among four user groups and ten rural amenity resources. The result of survey showed that most of respondents had been aware of amenity resources and the industry group had the highest level of utilization in making decisions for rural development. Although the significant difference among groups was not shown in the priority, the priority in the construction of information map was shown the significant difference among 10 kinds of amenity resources. Landscape's map and traditional resource map were relatively higher priority than the other resource map.

  • The purpose of this study was to evaluate the urban park and the green spaces within the public service framework. It was investigated by identifying the priority elements as defined by the residents and to figure out the differences of residents' satisfaction for the parks in new and old downtown. This study surveyed 455 residents from 80 dong (neighborhoods) of 5 Gu(districts) in Daejon. In this study, satisfaction on the urban parks and the green spaces in the old downtown was compared with the new town area. The results were as follows: Those who lived in the new downtown areas showed higher satisfaction than those in the old downtown for the urban parks and the green spaces, as well as in all 8 other evaluation sections. Both new and old downtown residents scored high on the 'city landscape and the natural environment' and 'green spaces and facilitats' items, but scored low on 'citizen's respect' and 'acceptance of resident opinions'. The old downtown residents highly valued on easy access to the parks, while the new downtown residents focused on various activities and programs, as well as resident participation, as the parks. The variables affected the resident's satisfaction on the urban parks in old downtown areas consisted of 'information', 'diversity', 'supply decision'. Among these variables, 'diversity' had the most significant influence on the satisfaction level.
