  • There are many factors to influence the amount of terpene at the forest. However, it is poorly understood whether the amount is altered by meteorological factors. In order to study correlation analysis between terpene amount and meteorological(i.e., temperature, humidity, wind speed, solar radiation) and environmental factors(i.e., oxygen, carbonb dioxide) at the artificial coniferous forest of Chamaecyparis obtusa (site 1) and Cryptomeria japonica (site 2) nearby the $1^{st}$ reservoir at Mt. Moodeung, the research was executed during April to November in 2011. Forest density at site 1 was 1,692 trees/ha, being occupied with 87.2% of Chamaecyparis obtusa, higher than 925 trees/ha at site 2. Carbon dioxide at site 1 was in the range of 385~410 ppm in June, similar to at Anmyundo(395 ppm in 2010). Solar radiation has positive correlation with ambient temperature and inversely negative with relative humidity. Main species of terpene released were ${\alpha}$-pinene, camphene, ${\beta}$-pinene, cymene, ${\delta}$-limonene and camphor at two sites and terpene was more effluent at spring and summer than at fall. The large amount of terpene was emitted in the afternoon than in the morning under the influence of the wind speed and the topographical property. The terpene amount has positive correlation with relative humidity and oxygen, and negative with wind speed and soil temperature. Because correlations of ${\alpha}$-pinene and other terpene materials showed statistically significant within p=0.01. ${\alpha}$-pinene could be suggested as the basic material in explaining the amount of other terpene materials.

  • This work aims to establish the landscape ecological countermeasures to improve the sustainability of urban mountain forest and to enrich the biodiversity in twenty mountains of the Seoul Metropolitan City. Landscape ecological analysis was conducted based upon various criteria, such as area and elevation of mountains, flora, naturalized plants, vegetation, forest types, mountain trails, and public facilities. Various measures were suggested for the better maintenances of floristic diversity, introduced plants, vegetation and forest types of urban mountain forests. Sustainable recommendations for land use adminstration were developed for the preparations of a climate change-adapted urban mountain forests, as well as rational managements of ecosystem, walking trails, and public facilities within mountain forest. Rich and diverse natural vegetation as well as high floristic diversity were reported at mountains with higher elevations, larger area size, and rich landscape diversity. Mountains with low elevation, small size with easy public access, however, might require an urgent action to decrease the burdens by anthropogenic disturbances and urban development.

  • The purpose of this paper is to examine the differences of user´s satisfaction of development elements of natural recreation forest(NFR) developed by public and private bodies in order to answer the research question: What is the differences of user´s satisfaction of development elements of NFR\ulcorner After reviewing the literature, mechanism of outdoor recreation, and development elements in NRF, we constructed the conceptual framework and have formulated the hypothesis of this research. We had obtained data through a questionnaire, which surveyed 584 visitors at 10 of the 72 natural recreation forests in Korea in 1999. We have analyzed the data using he descriptive statistical method, the mean difference test, and logistic regression method. We have found that 1) all the development elements have turned out to be significantly different from the mean difference test, 2) the two elements of atmosphere and activity have turned out to be statistically significant in determining the difference of NFR developed by public and private body in logistic regression analysis while user´s satisfaction in recreational resources, facilities and service make no differences between public and private NRF, 3) the higher the degree of user´s satisfaction in atmosphere and activity at NFR, the more the NFR developed by private body, and 4) their relative contribution of atmosphere and activities on whether the NFR is developed by public or private body have been turned out to have 0.258 and 0.242 respectively, which have a similar importance. The research results suggest that a guideline for the creation of marketable NFR by public and private developer, and development of use-programs and recreational atmosphere be recommended in the planning and development process of NRF. The approach and anlaysis method adopted by this research is highly useful for an evaluation of NRF developed by the tow bodies and development of devices for increasing user´s satisfaction and marketing positioning of NRF by the tow developers. It is recommended that more empirical study on individual development elements affecting user´s satisfaction be performed in the future.

  • This study was carried out to quantify degree of contribution of harvested wood product (HWP) on mitigation of climate change by valuation of public benefits, environmentally and economically. The potential carbon dioxide emission reduction of HWP was estimated by accounting carbon storage effect and substitution effect. Based on 2014 statistics of Korea Forest Service, domestic HWPs were sorted by two categories, such as wood products produced domestically from domestic and imported roundwood. The wood products were divided into seven items; sawnwood, plywood, particle board, fiberboard (MDF), paper (including pulp), biomass (wood pellet) and other products. The carbon stock of wood products and substitution effects during manufacturing process was evaluated by items. Based on the relevant carbon emission factor and life cycle analysis, the amount of carbon dioxide emission per unit volume on HWP was quantified. The amounts of carbon stock of HWP produced from domestic and from imported roundwood were 3.8 million $tCO_{2eq}$., and 2.6 million $tCO_{2eq}$., respectively. Also, each reduction of carbon emission by substitution effect of HWP produced from domestic and imported roundwood was 3.1 million $tCO_{2eq}$. and 2.1 million $tCO_{2eq}$., respectively. The results of this study, the amount of carbon emission reduction of HWP, can be effectively used as a basic data for promotion of wood utilization to revise and establish new wood utilization promotion policy such as 'forest carbon offset scheme', and 'carbon storage labeling system of HWP'.

  • This study was conducted in the spring of 2005 through personal interviews to examine the opinions of forest products manufacturers and consumers about the perspective of forest certification in South Korea and to characterize those consumers who expect the activation of a forest certification system in South Korea. Study results indicated that consumers showed more positive aspect for the activation of forest certification than forest products manufacturers. Respondents who had a negative view for establishing a forest certification system in South Korea pointed out a lack of customers' demand for certified wood products as the most important reason. Results also showed that, even when a forest certification system would be introduced as a possible policy for helping to attain sustainable forest management, it would take at least 5 to 10 years to establish a forest certification system in South Korea. To facilitate the establishment of the system, many respondents suggested that an increased public awareness of forest certification systems was the most required precedent condition, and government for manufacturers and forest management association for consumers had to certify forest management practices as a competent organization. A profile of consumers who expected the activation of a forest certification system would describe in relative terms as the highly educated female who interviewed in the city of Seoul and of the 20 age bracket. Although there were an increased public awareness and positive prospective of forest certification by consumers and forest products manufacturers, it is required to arouse much more interest of consumers about the system.

  • This study was conducted to grasp users' preferences and behavior of forest paths and to provide basic data for forest path construction in the future. Among forest path users, males and females over 20 years old were surveyed on forest path preferences, motives for visiting, using time and distance, companions, and sources for obtaining information on forest paths. A total of 587 people participated in the questionnaire, and cross-analysis was conducted simultaneously using the SPSS statistical program. In analyzing the preference of forest paths, it was found that male and the general public preferred trekking path for activities while female and foresters preferred forest path for relaxation and healing (p<0.05). As for the motives for visiting forest paths, the response that they visited for a walk/rest was the highest in gender, occupation, and age group. As for the number of annual visits, less than 5 was the highest in overall, and foresters tended to visit forest path more often than the general public, and the number of visits to the forest paths increased with age (p<0.01). The most common route to acquire information about forest paths is the Internet, while the Internet use is relatively low in those over 60s (p<0.05). The response ratio of accompanying their family in visiting forest paths were the highest, while the response in their 20s and 60s was the most in accompanying their friends (p<0.05).
