  • This examination of vegetation is conducted from June to Oct. 1999 through on the spot survey, centering on the habitat of Abies koreana around Imgeolryeong, Jangteomok, and Jeseokbong in Mt Jiri and Yeongsil path and Seongpanak path in Mt. Halla. Species composition tables of the Abies koreana community by altitude and slope in Mt. Jiri and Mt. Halla are made based on the community composition tables examined in quadrat. The Abies koreana-Saso quelpaertensis community in a west slope of Mt. Halla is found that Abies koreana of 4-6m in height forms subtree layer and that of 8-9m in height the tree layer and it reflects a difference between community structure by slope and main composition species. While the tree layer of Abies koreana community is 12-14 in height around the area of 1,290-1,560m above the sea of Imgeolryong and path from Baekmudong to Jangteomok, it is 8-12m in height in the area of 1,680-1,780m above the sea of path from Jangteomok to Jeseokbong. It means that community structure depends on area and attitude. This study finds out that commonly appearing composition species similar to coverage and presence are Lepisorus thunberianus, Quercus mongolica, Solidago virga-aurea var. asiatica, Ligularia fischeri, Carex lanceolata, Clintonia udensis, Magnolia sieboldii, Betula ermani, Acer pseudo-sieboldianum. As soil environment of surveyed area, pH of surveyed spots is similar in Mt. Jiri and Mt. Halla, electrical conductivity is higher in Mt Jiri, and contents of organic matter is relatively higher in a west slope of Mt. Jiri and Mt. Halla and lower in their south and west slopes. Contents of organic matter and total nitrogen show that the area of 1,550m above the sea in a west slope of Mt. Halla is some higher. For pH and contents of total nitrogen and organic matter, Mt. Halla is higher than Mt. Jiri but for electrical conductivity, Mt. Jiri is relatively higher than Mt. Halla.

  • This study was carried out to analysis change of distribution and habitat location environment of Korean Fir which is typically vulnerable species by the climate change in Mt. Jiri and Halla. Korean Fir was decreased 18% during 27 year since year 1981, Mt. Halla was 34% during 15 years since year 1988. In the same periods, Temperature change was increased from 8.56 to $9.36^{\circ}C$, from 11.2 to $12.1^{\circ}C$. Distribution changes by the elevation showed higher change ratio 1,400~1,600m in Mt. Jiri and 1,200~1,900m in Mt. Halla. Changes of Korean Fir each slope aspects was high $180{\sim}360^{\circ}$ in Mt. Jiri, $45^{\circ}$ in Mt. Halla. In slope was $30^{\circ}$ in Mt. Jiri and $20^{\circ}$ in Mt. Halla. Changes by reliefs was 12 in Mt. Jiri, 0 or 15 in Mt. Halla, and Sites of Korean Fir was convex slopes both of two areas. Changes by soils was in the good drainage textures.

  • 본 연구는 우리나라의 남부 지방인 전남 광양의 백운산 지역(해발 800 m)에서 자라는 60~70년생 신갈나무림과 제주 한라산 지역(해발 1,000 m)에서 자라는 60년생 신갈나무림의 바이오매스와 에너지 고정량을 추정하기 위해 각 지역별로 5~9 본씩 총 25 본의 표본목을 조사하였다. 광양 백운산 지역 북사면 신갈나무림의 바이오매스 현존량은 288.4 ton/ha, 남사면은 241.9 ton/ha이었으며, 제주 한라산 지역 북사면은 368.4 ton/ha, 남사면은 364.3 ton/ha로 나타났다. 또한 연간 순생산량은 백운산 지역 북사면 20.7 ton/ha/yr, 남사면 17.7 ton/ha/yr이었다. 한라산 지역 북사면은 19.0 ton/ha/yr, 남사면 21.2 ton/ha/yr로서 바이오매스 현존량과 연간 순생산량 모두 한라산 지역이 백운산 지역보다 더 높게 나타났다. 그러나 잎의 생산 효율인 순동화율(NAR)은 백운산 지역(4.1~5.1)이 한라산 지역(3.7~4.6)보다 더 높게 나타났다. 한편, 광양 백운산 지역에서 북사면 신갈나무림의 에너지 현존량은 5,666 GJ/ha, 남사면은 4,793 GJ/ha이었으며, 제주 한라산 지역에서 북사면은 6,550 GJ/ha, 남사면은 6,435 GJ/ha로 나타났다. 연간 에너지 고정량은 백운산 지역 북사면 365 GJ/ha/yr, 남사면 360 GJ/ha/yr, 한라산 지역 북사면 351 GJ/ha/yr, 남사면 347 GJ/ha/yr로서 백운산 지역이 한라산 지역보다 더 높은 것으로 나타났다.

  • 정상 등반만 지향하는 한라산에서의 탐방 문화를 개선하고, 한라산의 자연 보존과 탐방객의 질적 만족도 향상을 위하여 한반도 산지와는 구별되는 한라산의 지형 특성을 활용한 자연해설 탐방 프로그램을 개발하였다. 윗세오름 대피소부터 장구목오름 사이의 1.5km 구간에서 진행되는 아고산대 탐방 프로그램은 아고산 생태계에 관한 전문 지식의 습득뿐 아니라 아고산 생태계의 취약성을 이해시킴으로써 소중한 자연 자원으로서 한라산 아고산대의 보존 필요성을 인식시키는 교육적 효과를 올릴 수 있다. 관음사 탐방로 입구부터 구린굴 상류 협곡 지대 사이의 1.5km 구간에서 탐방로를 따라 흐르는 병문천에서 진행되는 산지하천 탐방 프로그램은 병문천의 지형 및 수문학적 특성을 바탕으로 한반도 하천과는 상이한 제주도 하천의 지역성을 효과적으로 소개할 수 있다. 두 자연해설 탐방 프로그램에서 다루고 있는 한라산의 아고산 초지대와 건천은 한반도에서는 체험하기 어려운 탐방 장소로서, 탐방 활동을 통하여 한라산 더 나아가 제주도 고유의 지역성을 탐방객에게 알리는 계기가 될 수 있다.

  • Dictyostelid cellular slime molds isolated quantitatibly from the oils of evergreen broad-leaved forest and moist grassland of mt. halla in korea. nineteen species were found, including four undescribed species. species underscribed in korea are dictyostelium aureum var. aureum, d. crassicaule, d. monochasioides, and polysphondylium tenuissimum. Among these isolates, d. crassicaule and d. monochasioides were found only in evergreen broad-leaved forest, and p.tenuissimum was commonly found in moist grassland and meadow. in warn temperate regions investigated, d. mucoroides occurred rarely. It was noticeadle that d. sphaerocephalum, d. aureum var. aureum and d. purpureum were much more commonly found in warm temperate region. Species diversity in evergreen broad-leaved forest was the highest among the forests investigated until now in korea. Many isolates in mt. halla distributed differently in relation to the vegetations and altitudes. distritution patterns of isolates from mt. halla were discussed.

  • The production and decomposition of litters and nutrient cycling of forests were studied at the pine forests such as Pinus densiflora, Pinus koraiensis, Pinus rigida, Pinus thunbergii, Abies holophylla and Larix kaempfer. The annual litter production of the P. densiflora forest was the most on Mt. Mudeung which was 620.75g/$m^2$ and the least on Mt. Halla which was 155.00g/$m^2$. The decay rate of litters was the highest at the P. densiflora forest on Mt. Mudeung which was k=0.256 and the lowest at the P. densiflora forest on Mt. Halla and A. holophylla on Mt. Jiri which were k=0.099. The half time of decomposition of litters was shortest at the P. densiflora forest on Mt. Mudeung and the longest at the P. densiflora on Mt. Halla and A. holophylla forests on Mt. Jiri. The average decay rate of the L. kaempferi forests which was k=0.204 was the highest and that of the A. holophylla forests which was k=0.122 was the lowest. The decay rate tended to decrease against increasing the altitude. The annual production of litterr, the contents of mineral nutrients and the amounts of mineral nutrients inputted into the forest soil tended to increase in proportion to the decay rate, k.

  • Roe Deer has been preserved for 25 years by the local government and the residents in Jejudo. However, the damage and harm of crops of the residents by Roe Deer are increasing as well. So, some experts worry about the unstability of ecosystem in Mt. Halla where Roe Deer live. This paper discuss the suitable number of Roe Deer population in Jejudo to protect the ecosystem in Mt. Halla and minimize the damage of residents in Jejudo. With system dynamics modeling and simulation, the population of Roe Deer at present is estimated about 2,300. However, the population of Roe Deer stays 'unstable balance'. So, a little change such as poaching and the increase of wild dogs may make the balance of ecosystem broken. According to the result of policy test simulation, we should keep on watching the poaching and maintain the number of wild dogs at about 100, so that the ecosystem in Jejudo can be stable. To reduce the moving of Roe Deer to low region, moreover, we should protect the Mt. Halla which is Roe Deer's habitat. If we are indifferent about these efforts, the ecosystem of Roe Deer in Mt. Halla will be ruined.
