This study was conducted to investigate the distributional characteristics of ground beetles and to provide basis information for biodiversity management including the ground beetles in the Naejangsan National Park area. Pitfall traps were installed throughout 20 sites within Naejangsan National Park during 2008 to 2011 to collect ground beetles. A total of 2,409 collected ground beetles were identified with 35 species belonging to 19 genera of 8 subfamilies. Coptolabrus jankowskii jankowskii, Eucarabus sternbergi sternbergi, and Pterosticus audax were dominant at the core area, while Pheropsophus jessoensis, Synuchus nitidus, Synuchus cycloderus, and Chlaenius naeviger were dominant at the border of the National Park and adjacent to the road or grassland. These differences of dominant species also affected to the similarity of species composition between core and border area, and caused increasing dissimilarities between sites with cluster analysis. Although the result of the present study was a case study using ground beetles, it will be helpful to develop a management strategy of biodiversity conservation in Naejangsan National Park and its surroundings.

The purpose of this study was to provide basic data for developing the practical park management. For this, satisfaction degree, satisfaction factors and estimated model by satisfaction variables of visitors analyzed through a questionnaire survey in Naejangsan National Park, Korea. In the evaluation of the satisfaction, variables of 'Lack of public facility'. 'Lack of use program', 'Lack of facility to stay' 'Charge of user fee, parking fee' and 'Exorbitant pay' at Naejangsan park office and 'Charge of user fee, parking fee', 'Lack of use program' and 'Lack of facility to stay' at Baekam park office was more unsatisfied than any other variable. Satisfaction factors by Factor Analysis were loaded with 'Facility management' at Naejangsan park office(34.3%) and 'user management' at Baekam park office(45.6%) by the highest contribution degree. In estimated model of satisfaction by Multiple Regression Analysis showed in order of 'damage of trail', 'Lack of commercial facility', and 'Littering problem' at Naejangsan park office and 'damage of cultural and historic resource', 'Lack of commercial facility', 'Touting' at Baekam park office. So, Naejangsan National Park needed intensive management policy and institutional apparatus for facility management and user education.

This study analyzed the distribution and structure of the vegetation landscape in Naejangsan National Park. The plant distribution was investigated using a field survey. There were 72 sites sampled using the clumpled sampling method. The data derived from the investigation was analyzed using the quantitative analysis of Bray-Curtis method. The analysis was performed by the classification of TWINSPAN. The ordination of DCA and RA was used for the species composition and successional trends. The results are as follows; 1. Quercus. serrata-Q. variabilis community as 21.76(16.49$\textrm{km}^2$), was the largest community in the actual vegetation of the Naejangsan National Park. The degree of green naturality index 8 area covered 64.8% of the study area and the index 6 area did 16%. 2. Classified by the ordination of DCA and environmental variables, such as the plant community was divided into seven groups according to the altitude and forming groups; Chamaecy Paris. pisifera-P.densiflora community, P.densiflora community, Q.variailis community, T.nuciofera-A.palmatum community. 3. Ther species diversity and evenness indices of C.pisifera-P.densiflora community, P.densiflora community appeared low but C.laxiflora communitywhich was the most stable community in the study area. 4. The similarity indices between Q.variabilis community and Q.serrata-Q.variabilis community were calculated 58.84%, but those between other communities were comparatively low level. 5. The successional trends of DBH class seem to be from C. pisifera-P.densiflora community, P.densiflora community to Quercus species community and from Q.variabilis community, Q.serrata-Q.variabilis community to Carpinus species community. 6. Results suggested that the successional trends in Naejangsan National Park; P.densiflora community\longrightarrowQ.variablilis community, Q.serrata-Q.variabilis community\longrightarrowC.laxiflora community in sequence.

The purpose of this study is to prove the factors affecting the fluctuation of daily visitors in five mountainous national park(Kayasan, kyeryongsan, Naejangsan, Soraksan, Songnisan), and to analyze the relationship between these factors and daily visitors in Korea. "Three Factors and Nine Categories"(Aoki, K. & Aoki, Y. : 1974, 1979) has been applied to this study, and statistical analysis method was carried out by computer program SAS and SPSS. The number of daily visitors is calculated based on the data of "Daily entrance ticket sale report" by administration office in each national park. The scope of time period is during the last 5years(1982∼1986: 1825days) and the results were as follows: 1) There were significant differences in the number of daily visitors of each national park among months, days of a week and weather-the same as the previous study of urban park case. But it wold be better for their category classification to be adjusted according to the fluctuation pattern of each national park. 2) The peak of monthly visitors comes in May(Kayasan, Soraksan, Songnisan) or October(Kyeryongsan, Naejangsan). These months are specified as group tour season. On the basis of monthly fluctuation pattern, Each national park were classified into seasonal type, that is, kayasan, Soraksan were proved to be three-season type(Spring, Summer, Autumn), Songnisan to be two-season type(Spring, Autumn), and Naejangsan to be one-season type(Autumn). 3) The weekly pattern differs from three category (weekday, weekend, holiday: Eom, Choi 1986) in the case of urban park study. And there is no significant difference in daily fluctuation pattern by weather (fine, cloudy and rainy day), but significant difference between snowy and the others. This result is due to the characteristics of visitors, which is, the major visits of national park are planned in a advance of the tour, therefore it is difficult to change the plan by the weather. 4) the result of correlation analysis showed that the most influential factor on national park use in Kayasan, Naejangsan, Soraksan and Songnisan is ′Monthly characters (M)′, on the contrary ′Day of week(D)′ in Kyeryongsan only. From the result, The more parks are resource-based, the more ′Monthly characters′-factor is supposed to affect the number of daily visitors rather than ′Day of the week′-factor. This means that kayasan, naejangsan, Sorakson and Songnisan are classified into resource-based type, but on the other hand Kyeryongsan should be classified into intermediate type.

We collected and identified 5,721 ectomycorrhizal fruiting bodies (EcM) from Naejangsan National Park from June 2004 to 2013, belonging to 1 phylum, 1 class, 6 orders, 19 families, 40 genera, and 196 species. Of these, 2,249 individuals were identified as 89 species belonging to 11 genera in 7 families in the Agaricales; 1,511 were identified as 43 species belonging to 2 genera in 1 family in the Russulales; 1,132 were identified as 50 species belonging to 21 genera in 6 families in the Boletales; 793 were identified as 8 species belonging to 3 genera in 2 families in the Cantharellales; 29 were identified as 3 species belonging to 2 genera in 2 families in the Thelephorales; and 7 were identified as 3 species belonging to 1 genus in 1 family in the Gomphales. Thus, most of the EcMs identified belonged to the following 3 orders: Agaricales, Russulales, and Boletales. Russulaceae were most common (43 species), followed by Boletaceae (39 species), and Amanitaceae (27 species); most individuals were Russulaceae (1,511), followed by Hydnagiaceae (1,071) and Boletaceae (804). The monthly distribution showed that the greatest number of individuals and species of EcM, including the dominant ones, occur around July~September at an elevation of 200~299 m, diminishing markedly above 600 m. The greatest number of individuals and species, including the dominant ones, were collected in the period with average temperatures $25.0{\sim}26.9^{\circ}C$, lows of $21.0{\sim}22.9^{\circ}C$, and highs of $30.0{\sim}31.9^{\circ}C$, relative humidity > 76%, and rainfall > 400 mm.
