  • 산림 내 시설은 산불 발생 시 접근성의 제한과 인접된 환경의 위험성으로 인해 큰 피해가 예상되는 시설이다. 또한 이러한 시설은 문화적 가치가 높은 문화재이거나, 사회적 파급효과가 큰 사회 간접 시설이 많아 이에 대한 효율적인 관리 방법의 제시가 필요하다. 본 연구에서는 이러한 산림내 시설의 정의와 위험성 구분을 위해, GIS를 이용하여 산림 내 시설의 지형적 환경을 분석하였다. 따라서, 수치 지형도에 의해 335개소의 산지 전용 가능 시설물을 추출한 뒤, 이를 통해 고도, 경사, 능선상의 위치를 분석하였다. 분석 결과, 문화재와 광산시설, 장례시설이 산불로부터 취약할 것으로 예상되며, 시설물의 분류 시설물 중 30%가 산림 내 시설물로 분석되었다. 보다 향후 추가적인 연구와 사례 검증을 통한 연구를 통한 지속적인 보강이 필요할 것으로 사료된다.

  • 개발계획이나 환경계획 수립시에 절대적인 해발고도를 기준으로 지형적 특성을 분석한다면 절대표고가 낮은 지역은 대부분 개발가능지로 구분된다. 따라서 지역적 특성을 반영하는 상대표고를 적용하여야 하나 산의 경계구획,능선설정 등의 어려움으로 아직 전국단위의 구체적인 연구는 미흡한 실정이다. 이에 본 연구에서는 최근 Weiss 가 제안한 지형위치지수 ( Topogr aph i c Position Index, TPI) 를 적용하여 전국 단위의 상대표고 분석 가능성을 검토하였다. TPI 모델 도출 결과와 기존 환경부 국토환경성 평가에 사용한 Gaia EZeye 모델 결과를 중첩 비교한 결과 정확도가 높은 것으로 나타났다.

  • The objectives of this study were to classify quantitatively vegetational types of P. densiflora for. erecta forest. The results were summarized as follows. 1) According to the canonical correspondence analysis(CCA), variables such as topography, altitude, available P/sub 2/O/sub 5/, and Mg/sup 2+/were highly correlated on three axes. Based on the correlations between vegetation units and environmental factors, Rhododendron micranthum community tended to be more distributed in the such situations of high altitude, upper topography, high C/N ratio, low level of Mg/sup 2+/and Ca/sup 2+/. Vaccinium koreanum community tended to be more distributed in the such conditions of high altitude, upper topography, high level of Ca/sup 2+/and Ma/sup 2+/. 2) According to the results of importance value analysis, Tree layer and Subtree layer in study areas showed high Ⅳ along with P. densiflora for. erecta, Quercus mongonlica, Q. variabilis, Q. serrata, Fraxinus rhychophylla and shrub layer indicated that Ⅳ of P. densiflora for, erecta in Sokwang-ri area was higher than those of the other areas. Therefore, it was considered that P. densiflora for. erecta forest of Sokwang-ri area could be naturally regenerated. 3) According to results of species diversity, the species diversity of Uljin region showed the least low value as 0.6622, other regions appeared about 0.7. In the diversity by vegetation types, Acer pseudosieboldianum community showed high value. 4) According to the analysis of community similarity, Sokwang-Ri region was lowly correlated with Uljin region, while the index among the other areas appeared above 0.6. 5) According to the analysis of interspecific association, it was divided into 2 groups. The species of first group were mainly involved in character species, and the species of second group were involved in differential species groups.

  • The status of eco-environments of Goryeong is evaluated from the results of National Ecosystem Survey. The areas, designated by the 1st class, are only 0.16% of total areas of Goryeong. Most of them are the regions which vegetation preservation status is well. Location of the 1st class region is mostly distributed around the summit and ridges of high mountains. The naturalness of Goryeong region is excellent, thus the status of eco-environments of Goryeong will be rapidly improved.

  • Based on the community structural attributes, such as species composition, diameter and height distribution, topographic position, and species diversity in the natural deciduous forest of Mt. Gari area, this study suggested desirable species and composition ratio to achieve ecological management of forests so as to maintain forest stability and enhance economical values. The results are as follows : 1. Twenty-five tree species were growing in the study forest. Of these Quercus mongolica, Pinus densiflora, Juglans mandshurica, Quercus serrata, Cornus controversa, Acer mono, Fraxinus rhynchophylla, and Tilia mandshurica were selected for desirable species through the evaluation of dominant and dominant potential. Kalopanax pictus, considered to be highly valuable species, was also included. 2. Taking account of different species composition pattern by topographic positions, we select as desirable species of J. mandshurica, C. controversa, Q. mongolica, A. mono, T. mandshurica, and F. rhynchophylla in the valley area, Q. mongolica, Q. serrata, A. mono, T. mandshurica, F. rhynchophylla, and K. pictus in the mid-slope area, and Q. mongolica, P. densiflora, Q. serrata, and Fraxinus rhynchophylla in the ridge area. 3. Based on the estimation of species diversity index for the overstory components, the reasonable forest stability levels of the indices were estimated at 1.96, 1.68, 1.94, and 1.27 for whole forest, valley, midslope, and ridge, respectively. 4. The recommended species composition ratios in the study forest were suggested Q. mongolica to be 30%, A. mono, F. rhynchophylla, Q. serrata, and T. mandshurica to be 10%~15%, J. mandshurica, P. densiflora, and C. controversa to be 5%~10%, and K. pictus to be 5%.

  • Saussurea chabyoungsanica was recorded in new species by Lim Hyoung Tak in 1997. In order to understand the entity of new species, we investigated the new distribution sites, vegetation structure and soil environmental factors. Additionally discovered distribution sites of S. chabyoungsanica were Manduckbong, Mt. Sukbyoung, Mt. Duckhang, and Sukgaejae, which were located on ridge of the Taebaek Mountains. Those sites are typical limestone zones of Korea and among them Sukgaejae belongs to lower great limestone area and Manduckbong, Mt. Sukbyoung and Mt. Duckhang belong to upper great limestone area. According to the result of phytosociological study, plant communities of S. chabyoungsanica were classified by 1 Community group, 4 Communities and 2 Subcommunities; Carex humilis var. nana-Saussurea chabyoungsanica Community group in wide sense Quercus mongolica Community group, Lespedeza maximowiczii-Saussurea chabyounsanica Community, Galium kinuta-Saussurea chabyoungsanica Community, Salvia chanryonica-Saussurea chabyoungsanica Community, Zabelia coreana-Saussurea chabyoungsanica Community. Environmental factor analysis of habitat showed that the distribution site of S. chabyoungsanica was ridge of North aspect and displayed pH $7{\sim}8$ typical of limestone. Soil moisture content was high, whereas organic matter content was low. Considering its high occurrence in sites of $1{\sim}10cm$ in soil depth, and of $30{\sim}45%$ in relative light intensity, major distribution sites were outcrops and boundaries between shrubland and forest. After community division by vegetation structure in habitat of S. chabyoungsanica, we investigated characters of soil environment by community. As a result of PCA analysis of soil sample by community, it was possible to divide community by characters of soil environmental factor. The cumulative value of contribution rate represented in second dimension space was 73% and the major factors for that value were soil texture, organic matter content and field capacity.
