Post-fire restoration can affect breeding bird communities and species compositions over a long-term period by determining pot-fire succession, and a long-term monitoring is therefore required to understand its impacts on forest birds. This study aimed to document the effects of post-fire restoration methods on breeding bird communities in three areas: unburned and two burned (nonintervention and intervention with clear-cut logging and planting) stands 13 years after the stand-replacing Samcheok forest fire at Mt. Geombong in Samcheok, South Korea. According to 108 point counts during the breeding season from April to June 2013, we found that the number of individuals, observed bird species, and species diversity index in intervention stands with clear-cut logging and planting were lower than that in nonintervention and unburned control stands. Foraging and nesting guild analysis also showed a lower abundance of foliage searchers, timber drillers, primary cavity nesters and secondary cavity nesters in intervention stands than in the other stands, while no significant difference was detected between the nonintervention and unburned stands. These results imply that an interventional restoration method may deter the recovery of avian breeding communities after forest fires, and also suggest that non-interventional restoration methods may be an effective way to benefit the species diversity and density of breeding bird communities.

This study was conducted to clarity the differences in density and body weight of rodents among unburned and two burned areas (silvicultured and natural restored areas) after forest fire from July to September 2004 in coniferous forest of Samcheok, Korea. The density of rodents was the least in the silvicultured area. There was no differences in density between the unburned and natural restored areas. Also, mean body weight of rodents in the natural restored area was higher than in the silvicultured area. Shrubs, seedlings, snags and CWD (coarse woody debris) would be good for inhabitation of the rodents in forest fired area. Therefore, coverage of understory layer should be maintained in forest fired area.

For the zoning of natural ecosystem, Vegetation Index is calculated from the vegetation data surveyed on Baekdudaegan (Pijae-Doraegijae). Five factors -biodiversity, conservation value of the stand, environmental quality, longevity of the stand, site productivity- are considered in the calculation of Vegetation Index. Vegetation Index might be a useful zoning tool for management of Baekdudaegan. For Vegetation Index I, 59 sample plots 52.2% of total 113 sample plots are belong to core area, 34 sample plots 30.l% and 20 sample plots 17.7% are belong to buffer zone and transition area, respectively. For Vegetation Index II, 49 sample plots 43.4% of total 113 sample plots are belong to core area, 38 sample plots 33.6% and 26 sample plots 23.0％ are belong to buffer zone and transition area, respectively.

As data basic to policy in nature conservation, the Degree of Green Naturality (DGN) survey was usually carried out. This also explains the impact of human interference to natural environment. Gongju gun and Yeongi gun were surveyed in the summer of 1983 to determine the DGN of these districts. Then, the surveyed DGN was compared to the existing standard. The results obtained appeared that the average DGN of these districts ranged about 5.1 to 5.9 and especially the ratio of DGN 7-graded area was high. Because of difficulties in applying the existing standard directly to middle part of Korea, further improvement on the existing standard for ranking or surveying the DGN should be reconsidered.

The present study was carried out to investigate both the actual vegetation and the degree of green naturality in the Chiaksan National Park. The results obtained are in the follows; The actual vegetation in the Chiaksan National Park were classified into 11 communities, including with the farmland and afforestation areas. According to the results, the Pinus community, as 36.83%. were the most largest community, and the Quercus mongolica, 22.35%. Quercus mongolica-Pinus densiflora community, which is mixed forest, 7.37%, and Pinus densiflora-Quercus mongolica community were 6.63%. The pure and mixed forest with these two species of Pinus densiflora and Quercus mongolica were the dominant species in the comunities of the area. The Degree of Green Naturality 9 was the widest area as 35.9% in the total area, the second was the Degree of Green Naturality 8 at 28.5 %.

본 연구는 1975년에서 1985년에 걸쳐 노년인구의 전체인구에 대한 상대적 비율 및 그 변화를 시도 단위의 지역적 차이에 역점을 맞추어 고찰한다. 노년인구의 비율에 변화를 준 사망, 출산 및 인구 이동의 인구 과정을 65세 이상의 노년인구와 65세 미만의 비노년인구의 순인구이동과 자연증가 개념으로 통합하여 분석한다. 1975-1980년, 1980-1985년 두 기간동안 서울 부산 및 경기도는 다른 지역에 비해 노년인구의 비율이 상대적으로 낮았으며 모든 지역이 동 기간동안 노년인구비율의 증가를 경험했지만 이러한 변화에 관련된 인구 과정의 영향은 노년인구의 비율을 지속적으로 증가시키는데 반해, 노년인구의 자연증가 영향은 1980년을 기점으로 커다란 대조를 이루어 1980년 이후에만 노년인구화를 증가시킨다. 특히, 1980-1985년 동안 비노년인구의 인구이동이 서울,부산 및 경기도의 노년비율은 감소시키고 타 지역의 비율은 증가시켜 모든 지역에서 노년인구비율의 변화를 결정하는 주요 요인으로 작용하였다. 비 노년인구인구의 이ㄷ오과는 다른 대상을 나타내는 노년인구의 인구 이동 역시 지역의 노년인구비율에 다양한 영향을 주었다. 끝으로 노년인구의 인구이동 및 노년인구의 집중현상에 수반되는 사회적 결과를 논의한다.

기후변화와 기후변동으로 인해 태풍과 홍수 등의 자연재난 발생빈도가 증가하고 있으며, 이로 인해 심각한 인적 경제적 피해가 발생하고 있다. 피해 정도와 규모는 각 지역의 사회 경제적 요소에 따라 큰 차이를 보이고 있지만, 일반적으로 특정 지역에서 발생한 피해는 연속적으로 타 지역에 영향을 미치고 궁극적으로 국가 경제에 심각한 타격을 주는 경향이 있다. 따라서 본 연구에서는 산업연관모형을 이용하여 태풍 '차바'로 인해 울산지역에 발생한 피해가 국가 경제에 미치는 영향을 평가하였다. 본 연구결과는 특정 지역에서 발생한 피해가 타지역 및 국가 경제에 어떤 영향을 미치는지 정량적으로 평가하였고, 효율적인 재난관리의 기초자료로 사용될 수 있을 것으로 기대된다.

This study aims to analyze the current status of government-designated cultural heritage that are protected as sacred natural sites, focused on natural monuments and scenic sites, and provide basic research for these cultural heritage to be included in the protected area category. First, among natural cultural heritage that are designated and protected by Cultural heritage Protection Law, there are 40 scenic sites and 126 natural monuments that have been selected as sacred nature sites. Second, the study showed that sacred nature sites are sacred places that have been long associated with happiness and misfortune of the villagers, including Dangsan Forest, Seunghwanglim(Forest), and, as physical environment and combination of cultural value, rules, and attitude and belief system toward the land that protect the people. The unique folk beliefs of the region provide strong protection of the place. Third, although the natural monuments of old and large trees are not included in the protected area as they are recognized sparsely, but can be designated as world protected area as protected areas are set around sacred nature sites. Fourth, in order to be included in IUCN category, sacred natural sites of scenic sites will need to be managed by specific categories of each area according to the interior status of the designated areas and maintain the sustainability of the natural heritage by protecting both physical and spiritual elements.

자연환경의 보전이란 현재 기존하고 있는 자연환경을 앞으로의 오염과 파괴에서 보호할 뿐 아니라 이미 파손된 것이라 하더라도 과거의 원형대로 복구시키는 노력이 포함되고 있는 것이다. 다시 말해서 경제개발이나 생산개발에 의하여 여태까지의 자연환경이 점차 파괴 또는 오염되어 가고 있음이 사실이나 이들은 곳에 따라 그 정도에 차이가 있는 것이다. 어떻게 말하면 급속적인 지역개발에 의하여 자연이 오염 또는 파괴되어 가고 있는 것이 현실이라 하겠다. 그러나 이것은 보다 나은 인간생활의 현상을 위하여 자연을 개조하거나 극복한다고 할 수 있으므로 이로 인한 환경파괴때문에 지구개발을 기피하여서는 아니 될 일인 것이다.(중략)
