  • 국립공원의 뛰어난 경승지와 생태적으로 보존가치가 높은 지역은 다음 세대에게 물려줄 국가의 귀중한 자원으로서 잘 보존되고 관리되어야 하나 한국의 국립공원에서는 공원의 자연환경을 해치는 개발행위가 이뤄졌거나 제안되고 있다. 이러한 개발행위를 효과적으로 평가하기 위해서는 관련 환경자원의 활용이 필요하고 특히 토지이용변화의 파악이 요구되나 한국의 국립공원은 적절한 토지이용도가 결여되어 있다. 그러므로, 본 연구의 목표는 토지이용변화도를 제작하여 향후 국립공원에서 제안되는 개발행위가 해당국립공원의 토지이용변화에 미친 영향을 파악함으로써 국립공원의 환경 및 경관 관리에 기여하는 데에 있다. 본 연구는 계룡산국립공원을 대상으로 1988년도부터 1998년까지의 토지이용변화를 파악하기 위해 원격탐사 자료를 이용하여 2개년도의 Landsat TM 영상을 기하보정하여 토지피복분류를 추출하였다. 이를 바탕으로 항공사진과 현지조사를 통해 확인하여 작성한 토지이용현황도와 토지이용변화도를 GIS에 입력하였으며 GIS의 분석기능을 이용하여 10년간의 토지이용변화에 대해 파악하였다. 토지이용변화 파악 결과, 농지와 나대지가 계룡산국림공원 전체에서 43.7ha, 102.2ha 각각 감소하였고 산림과 개발지는 121.Oha, 24.8ha. 각각 증가하였다. 산림의 증가는 1988년 영상분류당시 산림의 가장자리 유령림이 농경지로 분류되었던 것이 10년 뒤 영상에서는 산림으로 분류된 결과로 파악되며 개발지의 증가는 계룡산국립공원 동학사 제2집단시설지구의 개발로 기존 농경지가 감소, 전용되었고 나대지는 개발로 인해 감소되었다. 개발지의 증가는 취락지구와 집단시설지구에서 두드러졌으며 이들 두 지구에서 산림, 농경지, 나대지 모두 감소하고 대신 개발지가 증가하였다. 본 연구를 수행한 결과 계룡산 국립공원의 가장 큰 토지이용변화는 건물 신축이었으며 이는 집단시설지구의 신설에 기인하고 있다. 취락지구도 개발 행위가 증가하고 있어 집단시설지구와 취락지구의 이용후 평가가 이뤄져야 한다고 생각한다. 본 연구에서 작성한 토지이용변화도는 향후 국립공원의 경관 변화를 파악하는 데에 효과적으로 이용될 수 있다고 판단된다.

  • Forest type map is a main forest thematic map which shows forest type, age class, diameter class and density. This map has been used as a base data in various fields such as forest policy decision-making, land suitability assessment and eco map production etc. But the existing map had many kinds of errors and no metadata because there was no standard for digital map production. On this study, we developed standard for digital forest type map production consisting of 33 unit processes including DB schema design, mapping process, quality control and metadata input process. Based on this standard, country-wide digital forest type map can be produced with consistent quality and standard metadata.

  • This study was aimed to identify determinants of users' satisfaction and behavioral intention in Jirisan trail of Korea and provide effective trail building and management strategy. The result of survey by 645 trail users showed that four dimensions were derived from 14 satisfaction items, which were experiential resources, cost resources, information, amenities. Of these dimensions, experiential resources along trails including natural environment, the level of trail development, trail condition, cultural & tourist resources, kindness of residents had the greatest effect on overall satisfaction and behavioral intention, which included revisit intention, recommendation intention and continuance intention. According to analysis by detailed variables, natural environment, road signs, kindness of residents and related information significantly affected overall satisfaction and behavioral intention.

  • This study considered Forest Specialists, who are nurtured by the legal system through the analysis of laws and regulations under the jurisdiction of the Korea Forest Service. In particular, the transition process of forest-related laws and laws to train forest specialists were identified. In addition, changes and characteristics regarding the cultivation of professional forestry talents according to forestry policy were investigated. As a result, it was found that Forest Specialist on policy dealt with forestry success for forestry promotion, and forestry engineers dealt with technical skills for forestry industry development. In addition, according to the revision of the laws for the sustainable use of timber, wood-structural engineers, timber grade evaluators, and timber education specialists are trained separately. Forest Specialists concerned with forest welfare policies were found to train forest experts and complete specialized training courses to provide various services for forest cultural and recreation facilities, healing forests, and forest leisure sports facilities. There is an instructor for forest leisure sports. Forest welfare experts are divided into forest education experts and forest healing instructors; forest education specialists are further divided into forest interpreters, forest guides for children, and forest trekking guides. Forest Specialists on forest protection policy were found to train arboretum and garden experts for the efficient management and exhibition of arboretums. Gardens and tree doctors and tree treatment technicians for arboretums wer also trained. A tree doctor and a tree treatment technician were found to have the necessary qualifications to run a tree hospital business, diagnosing and treating tree damage. Therefore, it is thought that the Korea Forest Service is nurturing Forest Specialists with technical capabilities for forestry promotion, forest industry development, and tree treatment; and the Forest Specialists can provide education and welfare services at culture, recreation, treatment, and conservation sites in forests.

  • This study tried to find out whether there is a change over time in the functional classification of forests in relation to human demand for forests. The level in which the concept of ecosystem services has been considered in national forest management plans was also examined. A total of 98 current and previous national forest management plans were available for this study. The composition ratios of the six functions of forests in both the current and previous national forest management plans were surveyed. We used a parametric t-test when the mean values of two (current and previous) groups were normally distributed and used nonparametric Wilcoxon code rank test when the assumption of normality was not met. Timber production forests were shown to follow a normal distribution, while five others, including water regeneration forests, disaster prevention forests, natural environment conservation forests, recreation forests, and living environment conservation forests were not shown to follow a normal distribution. Timber production forests and natural environment forests showed significant changes in the proportion of forest area between previous and current forest management plans. The concept of 'ecosystem services' began to actively appear in the 6th Basic Forest Plan, which started in 2018. However, the level of frequency of the ecosystem services mentioned varied by Regional Forest Services.

  • Predicting forest productivity is essential to evaluate sustainable forest management or to enhance forest ecosystem services. Ordinary least squares (OLS) and partial least squares (PLS) regression models were used to develop predictive models for forest productivity (site index) from the site characteristics and soil profile, along with soil physical and chemical properties, of 112 Quercus mongolica stands. The adjusted coefficients of determination (adjusted R2) in the regression models were higher for the site characteristics and soil profile of B horizon (R2=0.32) and of A horizon (R2=0.29) than for the soil physical and chemical properties of B horizon (R2=0.21) and A horizon (R2=0.09). The PLS models (R2=0.20-0.32) were better predictors of site index than the OLS models (R2=0.09-0.31). These results suggest that the regression models for Q. mongolica can be applied to predict the forest productivity, but new variables may need to be developed to enhance the explanatory power of regression models.
