        In order to investigate distribution of vascular plants along elevational gradient in the Nodong valley of Gyebangsan, vascular plants of eight sections with 100-meter-high were surveyed from the Auto-camping site (800 m) to the top of a mountain (1,577 m). There were a total of 382 taxa: 89 families, 234 genera, 339 species, 7 subspecies, 34 varieties, and 2 forms. As a result of analyzing the pattern of species richness, it showed a reversed hump-shaped with minimum richness at mid-high elevation. As a result of analyzing habitat affinity types, the proportion of forest species increased with increasing elevation. But, the ruderal species decreased with increasing elevation, and then increased at the top of a mountain. As for the proportion of life forms, the annual herbs gradually decreased with increasing elevation, but it did not appear between 1,300 m and 1,500 m and then increased at the top of a mountain. The trees gradually increased with elevation and decreased from 1,300~1,400 m. The vascular plants divided into four groups by using DCA. The arrangement of each stands was arranged in order from right to left on the Ⅰ axis according to the elevation. The distribution of vascular plants is determined by their own optimal ranges of vegetation. Also, rise in temperature due to climate change affects the distribution of vascular plants, composition, and diversity. Therefore, continuous monitoring is necessary to confirm ecological and environmental characteristics of vegetation, distribution ranges, changes of habitat. Furthermore, plans for conservation and management based on these data should be prepared according to climate change.

        치악산국립공원 성남지구의 고도별 온도변화에 따른 관속식물의 수직분포 및 분포변화를 파악하기 위 해 성남공원지킴터(450m)에서 남대봉(1,181m)까지 해발 100m단위로 등분하여 8개 구간에 대한 식물목 록을 작성하였다. 총 4회에 걸쳐 현지조사를 실시한 결과 관속식물은 99과 275속 419종 6아종 39변종 5 품종 1교잡종의 총 470분류군으로 조사되었다. 해발 600m(WI=78.2℃·month)를 경계로 관속식물의 출 현종 수가 급격히 감소하였다. 귀화식물은 저지대(해발 600m 이하)에서 높은 비율로 출현하였다. DCA기 법을 이용하여 출현종의 고도별 분포변화를 분석한 결과, 해발 600m와 900m를 경계로 3개의 그룹으로 구분되었다. 구간별 관속식물 분포의 유사성 및 상이성을 확인함으로써, 고도에 따른 온도변화가 그 식 물분포의 양상에 영향을 미칠 수 있음을 확인할 수 있었다. 호적범위는 식물종의 분포를 결정하기 때문 에 기후변화에 의한 기온상승은 현재 생물종의 분포와 그 다양성에 영향을 미칠 것으로 판단된다. 따라 서 식물의 생태․환경적 특징과 분포역, 생육지의 변화를 파악하기 위한 지속적인 모니터링이 필수적이다. 나아가 이러한 자료를 토대로 기후변화에 따른 식물자원의 보전 및 관리방안을 마련해야 할 것이다.

        This study was carried out to investigate the flora of indigenous habitat of Donghae-si and Samcheok-si in Gangwon-do, Korea. The vascular plants were collected 18 times (from March to October 2011), and were identified as 804 taxa; 127 families, 445 genera, 720 species, 8 subspecies, 69 varieties, 5 forms and 2 hybrids. In the flora of this area, the calcicolous plants were 55 taxa; Cheilanthes argentea, Clematis serratifoliam, Quercus variabilis. Epipactis papillosa, etc. The endangered plants designated and protected by the wildlife protection law, the Ministry of Environment, Korean were counted to one taxon; Cymbidium macrorhizum. The red list of vascular plants according to IUCN valuation basis were examined, endangered species (EN); Prunus yedoensis and Cymbidium macrorhizum, Vulnerable species (VU); Juniperus chinensis, Pulsatilla tongkangensis, Diarthron linifolium and Swertia wilfordii, Near Threatened species (NT); Paeonia japonica, Allium senescens, Epipactis papillosa and Pogonia minor, Least Concern species (LC); Asplenium ruta-muraria, Platycladus orientalis, Monotropa hypopithys and Eleutherococcus divaricatus var. chiisanensis, etc., Data Deficient species (DD); Paeonia lactiflora var. trichocarpa, and Not Evaluate species (NE); Prunus choreiana, Panax ginseng and Polygonatum infundiflorum etc. Korean endemic plants of this area were 26 taxa; Aconitum pseudolaeve, Corydalis hirtipes, Vicia chosenensis, Salvia chanroenica and Hemerocallis hakuunensis, etc. The floristic regional indicator plants found in this area were 130 taxa comprising 11 taxa of grade Ⅴ, 15 taxa of grade Ⅳ, 33 taxa of grade Ⅲ, 15 taxa of grade Ⅱ, 56 taxa of gradeⅠ.

        This study was carried out to investigate the vascular flora of Mt. Munsu. The vascular plants collected in 13 times(from Mar. to Oct. 2009) were identified as 511 taxa in total, including 113 families, 332 genera, 445 species, 5 subspecies, 46 varieties, 5 forms. Among them, 6 taxa of the Korea Forest Service-designated rare & endangered plants and the Korean endemic plants were identified as 2 taxa. Based on the list of approved for delivering overseas of plants, 6 taxa were recorded in the investigated area. The Ministry of Environment-designated plants, which should be protected by the wildlife protection law, were identified as 2 taxa and 39 taxa of specially designated plants by the Ministry of Environment. The naturalized plants were identified as 53 taxa, and their naturalization ratio and urban index were found to be 10.3%, and 18.5% respectively. There existed many kinds of plants resources having conservational value like Ranunculus trichophyllus var. kadzusensis, Jeffersonia dubia etc. in this area, but there remains a fear of nature destruction's acceleration due to indiscriminate human development and access of a lot of visitors, so it is judged that there should be a management plan, such as a limit on the number of visitors or rest-year-system for restoration of nature.
