채종원관리를 효율적으로 관리하기 위하여 시설되는 저 규격도로는 대부분 비포장상태로 이용되는 경우 많다. 이는 강우에 의한 침식붕괴로 하류의 산림식생환경 및 수질환경 오염으로 연결될 위험성이 내포되어 있어 적절한 방법으로 사전에 방지할 필요가 있다. 본 연구에서는 환경과 친화적인 재료를 최대한 이용하여 개발된 목배수로를 내구성 강화를 검토하였던바 섬유질 포의 조절과 고무질의 성능 조절에 의한 검토로 현장에의 적용이 가능하였다.

산림은 목재와 산채의 생산과 같은 물질생산의 기능이 있는 동시에 탄소를 고정하고 산소를 배출하는 광합성작용을 통하여 대기를 정화하며 지표토양의 침식을 방지한다. 또한 산림은 여러가지 동식물의 서식처로서 생물다양성을 보존하는 데 대단히 중요한 역할을 하는 동시에 도시민에게 휴식처를 제공하기도 한다. 이러한 산림의 다양한 기능 가운데 그 가치가 공식적으로 인정이 되고 있는 것은 목재나 약재와 같이 시장에서 유통되는 임산물의 생산기능에 제한되고 있어 산림자원의 효율적인 이용과 관리를 어렵게 하고 있다. 이러한 문제를 해결하기 위하여서는 산림이 지니고 있는 환경보전기능에 대한 평가가 이루어져야 한다. 이 논문에서는 최근 서구 제국에서 진행되고 있는 산림의 환경보전적 가치의 평가에 관한 연구 추이를 살펴보고 이러한 산림의 환경보전적기능의 평가를 뒷받침할 수 있는 이론적 체계를 정립하고자 하였다. 환경자원평가 방법을 산림의 환경보전가치 평가에 적용할 수 있는가를 검토하였으며, 적용장의 문제점을 살펴보았다. 산림의 환경보전적 가치를 평가하고자 할 경우에는 대부분의 경우에 있어서 생산함수법을 우선적으로 사용하고, 이 방법의 적용이 불가능할 경우 가계생산함수법과 실험시장법은 보완적으로 사용하는 것이 바람직하다고 생각된다.

This study was carried out to analyze water cycle characteristics and evaluate water retention function in Jeju Gotjawal forest from 2013 to 2017. The average ratio of throughfall, stemflow, interception loss in Seonhul Gotjawal (SH) and Cheongsu Gotjawal (CS) was 43.1%, 15.8%, and 41.1%, respectively. Rainfall-throughfall, rainfall-stemflow, and rainfall-interception loss were expressed as linear regression equation (p<0.001). The comparison results showed that SH was higher than CS (p<0.05), indicating that the canopy area had an important effect on the difference in stand structure. The average water resources retention rate of the Gotjawal region was 41.9%, which is similar to the total water resources retention rate (40.6%) of Jeju Special Self-Governing Province (JSSGP). Currently, the development of Gotjawal is in progress in JSSGP. The development of Gotjawal will lead to a decrease in the water resources retention rate due to changes in the surface environment such as an increase in impervious areas, which will affect the total groundwater content of JSSGP. Therefore, the conservation of the Gotjawal area is judged to be very important from the point of view of water conservation.

This study was conducted to find out the psychological or physiological healing effects of real natural forests and virtual forest experiences using virtual reality (VR) in an artificially-controlled digital environment. To find out this, 81 healthy undergraduate students from C University were experimented on visual forest stimulation effects in the digital environment from September 5 to December 9 in 2022. The experiment evaluated the psychological and physiological healing effects of visual forest stimulation in the digital forest environment (2D, 3D). The SRI (stress response inventory) experiment for analyzing psychological effect showed statistically significant differences among groups. As for the SRI experiment for measuring psychological stress, except Control group, 2D group in the digital environment showed little difference before and after the experiment. But 3D group showed less stress than before. As a result, it was proved that visual forest stimulation in a forest-based digital environment (2D, 3D) reduces psychological stress significantly. And when analyzing how visual forest stimulation changes EEG (electroencephalogram) in the digital environment, alpha waves (RA), which are activated during relaxation or stabilization, were more active than beta waves (RB), which are activated during tension or awakening. This study is expected to be used to create a psychological and physiological healing environment for those who cannot go to a natural forest due to mobility difficulties by providing them visual forest stimulation experiences in a digital environment. It is also expected that the results will be the basis for forest healing in the digital environment and virtual reality programs will help forest healing activities.

To improve on the efficient management of forest resources, it is necessary to create a forest soil map, which represents a comprehensive database of forest lands. Although a 1:25,000 scale forest site map has been used in Korea, the need for a large-scale forest soil map with high precision and information on forest lands that is specialized for individual purposes has been identified. Moreover, to keep pace with the advancement in forest management and transition to a digital society, it is essential to develop a method for constructing new forest soil maps that can diversify its use. Therefore, this paper presented a developmental process and used a 1:5,000 scale forest soil map to propose future directions. National maps showing the soil type, depth, and texture were produced based on the survey and analysis of forest soils, followed by the Forest Land Soil Map (1:5,000) Production Standard Manual. Alternatively, forest soil map data were the basis on which various other maps that can be used to prevent and predict forest disasters and evaluate environmental capacities were developed. Accordingly, ways to provide appropriate information to achieve the national forest plan, secure forestry big data, and accomplish sustainable forest management that corresponds to the national development plan are proposed based on results from the current study.
