the geoecology of the alpine and subalpine belts of the Korean Peninsula, its component plant group, its environmental history, and climatic amplitudes of the arctic-alpine and alpine plants has reviewed and discussed. The present-day alpine and subalpine landscapes are likely to have been formed during the post-glacial warming phase. The disjunctive distribution of many alpine and subalpine plants, however, suggests a former continuous distribution of these both locally and on a broader, and the subsequent breakdown of a former continuous range into fragments as the climate ameliorated during the post-glacial warming phase. The presences of numerous arctic-alpine and alpine plants on the alpine and subalpine belts of the Korean Peninsula, are mainly their relative degree of sensitivity to high summer temperatures. The continued survivals of alpine species and landscape in Korea is in danger if global warming associated the greenhouse effect takes place.

Reconstruction of the past vegetational changes of Korea in connection with climate changes enables to understand the impacts of past and future global warming on alpine vegetation. Despite the early appearance of the cold-tolerant vegetation since the Mesozoic Era. the occurrence of warmth-tolerant vegetation during the Oligocene and Miocene implies that most of alpine and subalpine vegetations have been confined to the alpine and subalpine belts of northern Korean Peninsula. The presence of cold-episodes during the Pleistocene. however. might have caused a general southward and downslope expansions of cold-tolerant alpine and subalpine vegetation. But the climatic warming trend during the Holocene or post-glacial period eventually has isolated cold-tolerant alpine and subalpine vegetation mainly in the northern Korea. but also on scattered high mountains in the southern Korea. The presence of numerous arctic-alpine and alpine plants on the alpine and subalpine belts is mainly due to their relative degree of sensitivity to high summer temperatures. Global warming would cause important changes in species composition and altitudinal distributional pattern. The altitudinal migration of temperate vegetation upward caused by climatic warming would eventually devastate alpine plants.

Cold environments, including polar and alpine regions, are colonized by a wide diversity of micro-organisms able to thrive at low temperatures. There is evidence of a wide range of metabolic activities in alpine cold ecosystems. Like polar microorganisms, alpine microorganisms playa key ecological role in their natural habitats for nutrient cycling, litter degradation, and many other processes. A number of studies have demonstrated the capacity of alpine microorganisms to degrade efficiently a wide range of hydrocarbons, including phenol, phenol-related compounds and petroleum hydrocarbons, and the feasibility of low-temperature bioremediation of European alpine soils by stimulating the degradation capacity of indigenous microorganisms has also been shown.

Ninety six plant species recorded at the alpine tundra zone on the Paektusan (Zhu and Rowe, 1987) were examined on the floras of alpine and subalpine zones in Korea. Among the 96 species, 59(61%), 47(49%) and 51(53%) species in the alpine zone of Kwanmobong, Turyusan and Puksubaeksan were recognized respectively, and 24(25%), 21(22%), 11(11%) and 16(17%) species in the subalpine zone of Myohyangsan, Kumgangsan, Soraksan, Chirisan and Hallasan respectively. The similarities between the alpine tundra zone of Paektusan and the alpine zones of other mountains in Korea showed high values than the values compared with subalpine zones.

The island alpine biogeography of Mt. Halla (Hallasan), Jeju Island (Jejudo), Korea is discussed. The presence of numerous species of alpine flora on Mt. Halla, the southernmost distributional limit for certain species, may primarily be attributed to palaeo-environmental factors, since it can not be wholly explained by reference to current environmental conditions. The alpine flora on the peak of Mt. Halla, mainly above 1,500m a.s.l, is evidently descended from immigrants from NE Asia via the Korean Peninsula during the epochs of the Ice Age. These plants, which are very intolerant of competition with temperate vegetation, have been able to persist in alpine belts thanks to their harsh climatic conditions, sterile soil, rugged topography and cryoturbation. The alpine plants on Hallasan are in a stage or process of retreat toward the mountaintop, most likely due to recent climatic amelioration. The lower limit of some species seems to coincide with maximum summer isotherms. The continued survival of arctic-alpine and alpine plants on the summit of Hallasan, Jejudo, the Korean Peninsula, however, is in danger, if global warming associated with the greenhouse effect continues.

본 연구는 한반도 내에서 한지를 선호하는 것으로 알려진 극지-고산식물과 고산식물의 분포를 고환경과 관련시켜 고찰하여, 이러한 식물들의 기원, 이동 그리고 도피과정을 밝히고, 아울러 한반도의 식생변천사를 파악함을 목표로 한다. 현재 한반도에는 75종의 극지-고산식물과 239종의 고산식물 그리고 105종의 한국 특산 고산식물등 약 419종의 한지선호식물이 생육하고 있는 것으로 알려졌다. 이러한 식물들은 주로 고산을 중심으로 격리 분포하고 있는데 그 이유는 첫째, 플라이스토세에 빙기가 다가오면서 극지와 그 주위에서 살던 식물들이 혹독한 추위와 건조를 피해 보다 양호한 생육 적지를 찾아 하산하거나 남하하여 이동하던 중, 한반도가 이들에게 일차 도피처가 되었던 것으로 본다. 그 후 빙기가 끝나고 간빙기나 후빙기에 들어서면서 기후가 온난해져 이러한 식물들은 기온 상승에 따라 발생되는 생육환경변화와 난지선호식물들에 밀려 고산이나 북방으로 이동하여 현재 격리되어 분포하는 곳에 이차 도피처를 마련한 것으로 간주된다 : 둘째, 특히 후빙기에 들어서 기후 온난화에 의한 저지와 산록지의 삼림발달은 빙기중에는 넓은 지역에 걸쳐 광분포하던 한지선호식물들을 격리시킨 것으로 사료된다 : 세째, 후빙기에 기후가 온난해지면서 사라지거나 축소된 한지선호식물 서식처도 이들이 격리되어 분포하는데 작용한 것으로 본다. 아울러 한반도 북부지방에 국한해서 139종의 고산식물이 출현하는 요인은 첫째, 이 지역과 동아시아 지역 사이에 고산식물의 교류가 용이했고 : 둘째, 북부지방에 산재하는 고산이 후빙기에 한지선호식물들이 도피해 생존할 장소를 제공해 주었으며 ; 세째, 산지들이 서로 연결되어 있어 필요할 때 식물들이 이동할 수 있는 통로가 될 수 있었으며 ; 네째, 북부 산지에 다양한 환경과 서식처가 마련되었기 때문으로 본다. 그러나 현재와 같은 기온 온난화 추세가 계속되면 한반도를 전세계적으로 혹은 동아시아에서 분포상 남한계로 삼는 많은 식물들이 멸종할 위기를 맞게될 것으로 사료되어 보존을 위한 대책이 요구되고 있다.

This study's objects are to predict distribution and to assess vulnerability of sub-alpine vegetations in the Korean peninsula for climate change using various climate models. This study validates relationship between sub-alpine vegetations and environmental factors using Pearson correlation analysis. Then, the future distribution of sub-alpine vegetations are predicted by a logistic regression. The major findings in this study are; First, spring mean temperature (March-May), total precipitation, elevation and warmth index are highly influencing factors to the distribution of sub-alpine vegetations. Second, the sub-alpine vegetations will be disappeared in South Korea and concentrated around Baekdu Mountain in North Korea. North Korea is predicted to have serious impact of climate change because temperature will be increased higher than in South Korea. The study findings concluded that the assessment of the future vulnerability of sub-alpine vegetations to climate change are significant.
