  • 최근 대규모 산림재해로 인한 산림환경 훼손 및 산림 농가의 피해는 물론 산림생태계에도 나쁜 영향을 미치고 있으며 이는 사회적으로 매우 민감한 환경문제로서 국민의 주요 관심사가 되고 있다. 본 연구에서는 울진군 전체를 대상으로 GIS 및 RS 기법을 이용하여 다양한 산사태 관련 인자들을 추출 하여 이를 기반으로 GIS 중첩 및 가중치 분석을 통하여 울진군의 산사태 발생 가능 위험지역의 분포도를 작성하고자 한다.

  • For the purpose of evaluating the restoration effect of vegetation, in this study, the areas where vegetation was restored had been monitored for 6 years, from 2008 to 2013. The areas were restored through some techniques by utilizing forest resources and nearby forest resources: biotope restoration method, forest topsoil paving method and small diameter trees planting method. Biotope restoration method is indicated the most similar properties to the existing natural forest just after they were restored because the forest likely to be deteriorated was transplanted. Forest topsoil paving method is expected that long-time will be taken for plants to grow to form the tree layer. However, the method is expected to acquire high restore the places of empty lands such as cutting areas. Community planting method is coverage can be increased for short time, relying on the sizes of planted trees, and the tree layer can be formed. Consequently, this method is expected to create high effect if the sizes of trees are considered after the right judgement of candidate site for restoration. This study is meaningful in that each type of restoration is monitored to observe the change of triggered by the succession process to forest. The study results can play as the reference data which can be utilized and applied to the area requiring vegetation restoration or to the area facing the damage of forest resources.

  • This study was carried out to evaluate the weight loss rates, carbon and nitrogen dynamics of wood stakes following soil amendment treatments (CLB: compound fertilizer + lime + biochar; LB: lime + biochar) in a post-fire restoration area, Ulsan Metropolitan city, southern Korea. Soil amendments in the fire-disturbed area were applied to two-times (Mar. and Jun. 2015, 2016) during the study period. Wood stakes on Mar. 2015 were buried at a top 15cm of mineral soil in two soil amendment and control treatments of Liriodendron tulipifera, Prunus yedoensis, Quercus acutissima, Pinus thunbergii plantations and an unplanted area in the post-fire restoration area. Wood stakes were collected at Oct. 2015, Mar. 2016 and Oct. 2016 to measure weight loss rates, organic carbon and nitrogen concentrations. Weight loss rates of wood stakes were not significantly affected by soil amendment treatments. However, remaining carbon of wood stakes were lowest in the control treatment (43.7%), followed by the CLB (71.3%) and the LB (71.6%) treatments. Remaining nitrogen of wood stakes was less in the control treatment (29.7%) compared with the LB treatment (52.6%). The results indicate that carbon and nitrogen mineralization of wood stakes in post-fire restoration area were delayed by soil amendment treatments.

  • This study was conducted to evaluate how the special protection area designations of degraded trails effect on the soil and vegetation recovery of degraded trails. The study areas were established on an opened trail and a 16-year closed trail, which was prohibited to enter after the designation as a special protection area for recovery, at Bukhansan National Park. Soil core sampling and measurements of vegetation cover were performed to compare soil and vegetation properties of the trails. Soil bulk density increased and soil water total nitrogen decreased on the opened trail, while no significant differences were found on bulk density, soil water, total nitrogen, acidity, and organic matter on the closed trail. On the opened trail, vegetation cover was seemed to be degraded, because vegetation litter cover ratio was low and barren rock cover ratio was high. On the closed trail, litter rock barren cover ratio of the closed trail was recovered, but only limited recovery was found on vegetation cover by applying environmental damage condition rating class. In conclusion, the closed trail was recovered by designation of special protection area, while difference in recovery progress of soil and vegetation was found. Therefore, designation of special protection area of degraded area should be based on scientific basis of recovery characteristics of the area. In order to improve the effectiveness of special protection area system, further specific standards for special protection area designation and management would be needed, considering ecological and social importance of target areas.

A Study on the Equity of the Charges Established to be Imposed on Damaging Activities of Natural Resources -A Comparative Study of Ecosystem Conservation Cooperation Charge and Replacement Charge for Forest Resources Creation- (자연환경 훼손에 관한 부담금의 형평성 제고방안 -생태계보전협력금과 대체산림자원조성비의 비교를 중심으로-)

  • These days, environmental policies have changed from being command and control systems toward economic incentive systems, with various incentives having been established by OECD countries. In Korea, many environmental charges have been established in order to diminish activities which damage natural resources. Among them, the Ecosystem Conservation Cooperation Charge and the Replacement Charge for Forest Resources Creation are considered to be representative environmental charges. These charges, along with a few others, were designed to encourage efforts to protect natural resources. The charges include a number of different features, utilize varying methods, and altered ranges of jurisdiction. However, the charges may pose serious inequity problems in terms of their estimated values and their conditions of reduction and exemption. For instance, although the Ecosystem Conservation Cooperation Charge is a primary charge applied to natural resource damage, the charge does not fully secure its original objectives due to its low levy and limited range of provisions. Moreover, the Replacement Charge for Forest Resources Creation has been criticized because of similar reduction and exemption provisions. Therefore, this study analyzes the inequity problems associated with the charges and proposes solutions. First of all, the Ecosystem Conservation Cooperation Charge should be redesigned in such a way that it reflects the substantial value of natural resource damage through either abrogate or increased maximum limits of the charge. With regard to the Replacement Charge for Forest Resources Creation, the cases and ranges of reduction and exemption provisions should be narrowed. Finally, the charges collected should be expended in conformity with their original objectives, and their expenditure should be restricted to either restoration activities or activities directly related to compensation and mitigation of damaged natural resources.
