지리산국립공원의 탐방객 수는 성삼재 접근도로가 개설되기 전인 1987년에 비하여 1996년에는 3.2배 1999년에는 약 2.3배 증가에 그쳤다 지리산국립공원 남부지역과 북부지역 탐방객중 성삼재를 경유하여 노고단으로의 등반비율은 10.6-52.8% 중산리 매표소를 통과해 천왕봉 정상을 향한 등반비율은 70.4-93.5% 수준이었다 피크시 능선부의 주요 지점별 탐방객 수는 대체적으로 노고단 천왕봉 장터목 세석평전 순으로 많았다 계절별 탐방패턴을 보면 남부지역은 가을철에 북부지역과 동부지역은 여름철에 탐방객이 집중하였고 요일별 차이를 나타내었다.

지리산국립공원 동부지역의 해발고와 사면에 따른 식물군집구조를 파악하기 위하여 1999년 7월에 49개의 조사구(20m$\times$15m)를 설치하여 조사하였다 해발고가 올라감에 따라 북사면에 위치한 조사구에서는 구상나무와 신갈나무의 평균상대우점치가 증가하였고 천왕봉 해발 1,700m이상 지역에서는 가문비나무가 우점종이었으며 해발고가 올라갈수록 상대우점치는 증가하였다 반면 남사면에 위치한 조사구에서는 해발고가 올라감에 따라 신갈나무의 평균상대우점치는 감소하였고 구상나무의 평균상대우점치는 증가하였다 해발고에 따른 북사면과 남사면의 종수와 개체수는 북사면에서보다 남사면에서 많았고 입지환경과 종간상관관계에서는 가문비나무 신갈나무, 잣나무가 해발고와 정의 상관관계를 나타냈으며 서어나무는 부의 상관관계를 나타내었다 동일 해발고에서도 사면상 위치에 따라 식물군집구조 및 종구성의 차이를 나타내었다.

Herpetofauna of Kojedo was surveyed in both May 3, 1998~May 5, 1998 and Nov. 7, 1998~Nov. 8, 1998. 9 species of 6 families in Amphibia and 9 species of 3 families in Reptile were observed by survey and heard the evidence in this study. It was observed relatively rich biota to the Kayasan, Sokrisan, Soraksan and Chirisan National Park in Korea. There were Specific Endangered Animal assigned by Minister of Environment such as Hynobius leechii, Bufo bufo gargarizans, Rana dybowskii, Elaphe rufodorsata, Zamenis spinalis, Dinodon rufo-zonatum rufozonatum, Agkistrodon blomhoffii bevicaudus and Agkistrodon saxatilis. Especially Rana catesbeiana which was originated from North America was very abundantly distributed at one pond. So Rana catesbeiana should be controlled for stable environmental condition of endemic Amphibia distribution.

This study was conducted to investigate seasonal avifauna and to suggest a proper way how to manage and protect wild birds in Chirisan National Park. The survey was carried over 3 main trail districts by line transect method to figure out influence factor of inhabitation of wild birds from February to November in 1991. The study results are as follows : The observed birds were belong to 6 orders 24 families 49 species and 981 individuals and Falco tinnunculus(Natural monument No. 323). These birds also classified into 24 species for residents, 12 species for summer visitor. 9 species for winter visitor, 4 species for passage migrant, respectively. The observed average frequeney of birds was 2.09e.a./ha, and main dominant species were Parus varius, Parus major, Emberiza elegans, Garrolus glandarius, Sitta europaea, Hypsipetes amaurotis, Parus palustris in order. Cheoneun-sa trail route showed relatively decreasing trend of wild birds during spring and fall season because of the highest trail use of visitors. Maximum frequency of species and individuals appeared at Hwaum-sa route in spring and at Piagol route in fall. respectively. Those regions well explained the advantageous inhabitation area of birds in both regions. The diversity index of birds in winter showed little difference of similarity index due to balanced use of trails. Seasonal low similarity index in those 3 main trail district indicate a dissimilarity of environmental factors. Trail use restriction as a provision of proper management and protection of wild birds have to be made at Hwaum-sa route where propagation of birds actively occurred in spring and at Piagol route where birds wintering were observed will contribute to enhance species diversity in the future.

Ecological approach to conservation of Korea's National Parks (KNP) was reviewed. Four hundred twenty five reports on 15 national parks for 80 years (1915~1994) were analyzed in consideration of phytocoenotic information such as flora, plant community and landscape. Total species was recorded as 157 familles, 752 genera, and 2,369 species (64.3% of Korean flora), in which is included only 75 species of the protected plant species designated by the Ministry of EnvironMent. Occurrence patterns of plant species in national parks were quite similar to one another, but those of plant community were rather unique. Seventy-four of 97 plant communities were reported in only one of 15 national parks, which might be regarded as an endemic or local vegetetation type. These facts are far different from actual status of the KNP＇s ecosystem, which indicate that not only original data in previous reports are less informative, but also tools of investigation and description are too subjective, and thus these can never afford to monitor the ecosystem. From the correlation analysis between 10 ecological characteristics, the following results were obtained: (1) the species richness was positively associated with the area of national park, (2) the number of visitors was related to landscape diversity, (3) occurrence of the designated species was closely related to the vegetation diversity. Numerical analysis (cluster analysis and ordination) using dissimilarity ratio by ecological characteristics divided 15 national parks into 4 groups. The first group, composed of national parks of Chirisan, $S\v{o}laksan$, Sokrisan, Hallasan, $T\v{o}kyusan$, Odaesan, and Sobaeksan, is recognized as the best national parks in terms of ecological conservation values. Nevertheless, they have been faced with the threat of visitor stress. This study will contribute to the establishment of strategy for appropriate conservation and sustainable use of KNP.

Users' norms, expectations and recreation motives are major influential factors on perceived conflict in recreation settings. This study was conducted to examine how information affects users' norms and expectations, and subsequently, the extent of perceived conflict. Data was collected at the Second Campground in Chirisan National Park in 1994. Of two hundred eighty on-site survey questionnaires distributed, 253(90.4%) were used for analysis. According to the result of the study, information changed users' normative standards in accord with the content of information and increased the extent of norm convergence. However, it did not change users' expectations and didn't reduce the degree of perceived canflict. The possible reasons were discussed. Some directions for more effective use of information to reduce perceived conflict were also suggested.

To investigate edge vegetation structure and species in the Chrisan National Park, filed survey was excuted from August to October, 1991 and the results were as follows. Importance values of species in lower layer were changed according to the distance from edge to forest interior at the northeastern slope of a highland. Change of vegetation structure was observed from edge up to 30m of forest interior and edge depth was estimated as 15~20m. The dominance and frequency of edge species seemed to be affected by the factors of altitude, aspect and topographic location. Especially, edge vegetation showed severe difference according to topographic location between a ridge and a foot of a mountain, and according to aspect between southern and northern slope above midslope region of a mountain. Comparing vegetation structure of lower layer for southern and northern slope, more no. of individuals and crown coverage were observed at northern slope, while more no. of species, species diversity and coverage of Sasa purpurascen at southern slope.

A natural mixed forest of Pinus densiflora and Quercus variabilis in Mt. Mohu area was studied to investigate patterns of species competition and productivity. Ten $10m{\times}10m$ plots were set up and eight sample trees of each Pinus densiflora and Quercus variabilis were harvested for dimension analysis. Mean tree age of Pinus densiflora was 33 years and that of Quercus variabilis was 26 years. DBH and height of Quercus variabilis were larger than those of Pinus densiflora untill tree age 15. After tree age 15, height of Quercus variabilis was higher than height of Pines densiflora while DBH of Quercus variabilis was smaller than DBH of Pines densiflora. For a tree of a given DBH, there was little difference in leaf dry weight between Pines densiflora and Quercus variabilis. For a tree of a given DBH, dry weights of stem wood, stem bark and branches of Quercus variabilis weighed more than those of Pinus densiflora, and the differences between the dry weights of the two species became greater as DBH increased. Net assimilation ratio of Quercus variabilis was higher than that of Pinus densiflora, and biomass accumulation ratio of Quercus variabilis was lower than that of Pinus densiflora. It may be given as a conclusion that Quercus variabilis was superior to Pinus densiflora in species competition owing to faster height growth, higher net assimilation ratio, and lower biomass accumulation ratio. Aboveground stand biomass was 87.7t/ha and aboveground stand net production was 8.3t/ha/yr.
