Having the Seorak mountain National Park as an object of study, this research grasps the problems of the present environmental observatories through the awareness investigations of visitors towards the function of environmental observatories made by the evironmental education. In order to achieve this, a questionaire has been conducted for 26 days, starting from the 25th October 2002, directed towards 100 visitors to the Seorak mountain National Park about the maps and degree of satisfaction of the usage ofthe environment observatory and explanation program. The results of the analysis show that general satisfaction on the environmental observatories are valued very negatively. This informs us that the present environmental observatories under the environment education are not fullfilling entirely their functions. Supporting itself upon the basis of the visitors' questionaire, this research has attempted the resolution of the present problems having as an object of study the scenery and cultural resources present in the Seorak mountain National Park, and proposing an entertaining environmental education of the environment observatory's constitution.

실험지역으로 선정된 거제도와 남해도에 대해 Yamada(1999)의 산치차수구분을 시도해 보았으며, 그 결과를 바탕으로 산지차수구분을 남한 전 지역에 확대·적용하였다. 남한 지역의 최고 산지차수는 5차수였는데, 설악·태백산지, 지리·덕유산지, 영남알프스산지 모두 3곳으로 확인되었다. 4차수 산지는 10곳, 3차수 산지는 87곳에 나타난다. 5차수 산지는 대략 한반도의 융기축과 관련이 있는 것으로 판단되며, 4차수와 3차수 산지의 분포는 2차산맥과 같은 북동-남서의 방향성을 지니고 있다. 한편 하천차수법칙과 마찬가지로 차수별 산지 개수, 면적, 비고의 로그함수 값이 차수에 대해 선형관계를 이루고 있다. 차수별로 구분된 산지 중에서 기존의 산맥체계에서 고려하지 않은 산체들을 확인할 수 있었는데, 이들은 한반도의 지체구조를 보다 자세하게 이해하는 근거로 활용될 수 있다. 국립공원 및 도립공원은 대부분 5, 4, 3차수 산지에 분포하고 있다. 특히 속리산국립공원이 남한 지역의 대표적인 두 산체인 지리·덕유산지와 설악·태백산지를 연결하는 생태축의 중요한 연결고리 역할을 하고 있음을 확인할 수 있었다. 이는 산치차수구분법이 지니고 있는 지형학적 의미뿐만 아니라 실용적 가치를 시사해준다.

Background: This study was conducted to assess the physicochemical water quality and the altitudinal distribution of low-temperature and mountain epilithic diatom (LTMD) community in Buk and Hangae streams that are located in Seorak Mountain with the height of 1708 m in Korea. And the community characteristics of LTMD found in the Buk and Hangae streams were compared to that of LTMD from the Han River system. Results: The physicochemical water qualities of Buk and Hangae streams were determined to be very clean. As a result of analyzing the community composition, 135 taxa of epilithic diatoms were determined, and 22 taxa appeared including Hannaea arcus var. subarcus which are known to have low-temperature and mountain ecological characteristics in the literatures. The relative frequencies of LTMD were 37.0~0.9% range from the upper to lower regions. Although Diatoma tenuis, Eunotia minor, and Gomphonema affine are known to be ubiquitous in streams and lakes, in this research, the three taxa were added into low-temperature and mountain epilithic diatom, since D. tenuis and E. minor appeared only in altitudes above 600 m, and G. affine had the highest relative frequency during spring and fall in altitudes above 700 m, when water temperature was around $10^{\circ}C$. Conclusions: Among the 24 taxa of low-temperature and mountain epilithic diatom (LTMD) (including the 3 taxa added in this study), 14 taxa (Diatoma hyemalis, D. mesodon, D. tenuis, Hannaea arcus, H. arcus var. subarcus, Ulnaria inaequalis, Eunotia bilunaris, E. implicata, E. minor, E. muscicola, E. silvahercynia, E. septena, Delicata delicatula, and Gomphonema affine) represented the characteristics of LTMD very well; they grow best in water temperatures below $15^{\circ}C$ in Buk and Hangae streams and Han River system.

Hyangro-bong is located on the northern side of the civilian access control line and therefore has gone through natural ecological succession without human interference. Currently, it forms a distinctive natural ecosystem in which rare wild animals and plants are various. It is located in the Baekdudaegan mountain system and plays an ecologically important role as a bridge that connects the Geumgang mountain and Seorak mountain. This study investigated the flora of the eastern parts, Forest Genetic Resources Reserve Area, of Hyangro-bong. A total of 363 vascular plants that belonged to 77 families, 206 genera, 310 species, 3 subspecies, and 47 varieties were found in the study area. Rare and endangered plants identified in this study included the critically endangered Swertia wilfordii and endangered Irisuniflora var. caricina. Furthermore, 4 vulnerable species, Hanabusaya asiatica, Codonopsis pilosula, Leontopodium japonicum, and Taxus cuspidata, were found. A total of 7 families and 14 taxa including Aconitum pseudolaeve and Clematis fusca var. coreana were confirmed as endemic plants. Naturalized plants belonging to 4 families, 11 genera, and 13 species were distributed along the Hyangro-bong forest roads.

The statistical analysis for the springtime windstorm in Korea shows that Yeongdong region has the highest occurrence frequency during recent 10 years. The objective of this study is to find possible mechanisms for the downslope windstorm formation in the Yeongdong region by using a mesoscale numerical model, WRF. Dynamical process, wave breaking (hereafter WB), is qualitatively investigated as the candidate mechanism for a windstorm event occurred in 5 April, 2005. WB is developed in upper troposphere downstream, since stable air is lifted by the Taebaek mountain. This process can cause and maintain the severe downslope windstorm by drawing the upper flow down to the surface. And the intensified downslope wind leads the hydraulic jump (hereafter HJ) in downstream region. Froude numbers at Chuncheon (upslope side), Seorak Mountain (crest), Yangyang (lee side), and the East Sea (distant downstream position) are estimated by about 0.4, 1.0, 1.6, and 0.6, respectively. This result implies that the accelerated and supercritical (Fr>1) flow adjusts to the ambient subcritical (Fr<1) conditions in the turbulent HJ. In addition, we find the formation of upstream inversion near top level of the mountain cause the intensification of HJ. Experiments to examine the orographic effect on the mechanisms suggest that the magnitudes of WB and HJ are larger in the experiment of higher topography, but there is no significant difference of windstorm magnitude among the experiments. Another important result from these sensitivity experiments is that the intensity of downslope windstorm strongly depends on the magnitude of upper (2~4 km) wind in upstream side.

This study examined the habitat status of wild birds at closed-trails and the control group of opened-trails in the national park of the Baekdudaegan mountains. After evaluating each area based on this, it's aimed at being utilized as basic data for future national park management and opening of trails. Upon field investigations and analyzing existing literary materials, it was found that there were a total of 76 bird species living around the trails. Among them, it was confirmed that 60 species can breeding and 10 species are protected by law. Upon assessing the scores of each area according to the evaluation standards of this study, Area I had 7 scores, area II had 13 scores, area III had 5 scores, and area IV had 16 scores, showing that the control group open-trail area IV between Jeongryeongchi and Seongsamjae had the highest score, and that area III of Wolyeongdae~Chotdaebong~Daeyasan~Miljae~Wolyeongdae had the lowest score. Evaluation of closed-trail according to wild bird species (Avifauna) was attempted in this study, but there were more bird species living in open-trails, while also having higher evaluation scores. Therefore, if opening trail is needed in the future due to excessive desires of visitors or inevitable social demands, it is judged that various environmental factors including mammals highly affected by people should be evaluated to open up the sector with the lowest score. Also, it is judged that through methods such as reservation systems, the number of visitors should be controlled or night-time hikes should be prohibited so that nocturnal wildlife can freely use the trails.
