덕유산의 향적봉과 남덕유산을 잇는 아고산지대(1.350~1.600m)에 분포하는 한국특산종 구상나무의 생육현황과 구상나무림의 군집구조를 정확히 파악하여 앞으로의 구상나무림 관리의 기초자료를 마련하고자, 구상나무가 분포하는 지역에 27개의 조사구(20m$\times$20m)를 설치하여 식생을 조사하였다. 덕유산 아고산지대 구상나무림의 종구성적 특성은 신갈나무 - 주목 - 구상나무군집이었다. 수종간의 상관관계에서는 주목과 병꽃나무; 호랑버들과 부게꽃나무; 백당나무와 호랑버들; 당단풍과 조릿대 등의 종들 간에는 높은 정의 상관이 인정되었고, 구상나무와 병꽃나무; 신갈나무와 노린재나무 등의 수종들 간에는 높은 부의 상관이 인정되었다. 해발고와 정의 상관이 인정된 것은 주목과 백당나무 등이었고, 부의 상관이 인정된 것은 쇠물푸레이었다. 구상나무의 활력이 저조한 것으로 나타났으며, 18.18%는 고사목이었다. 구상나무 고사목은 흉고직경 10~30cm 의 범위에 드는 것들이 대부분이었다. 생육현황표의 점수 평균은 11.73점이었고, 점수와 토심과는 고도의 부의 상관이 인정되었다.

To investigate the structure and the conservation strategy of Taxus cuspidata forest at Janggunbong area in Taebaeksan, 18 plots(20m$\times $20m) set up with random sampling method were surveyed. Major woody species growing with Taxus cuspidata were Acer pseudo- sieboldianum, Euonymus macroptera, Prunus padus, Abies nephrolepis. High positive correlations was proved between abies nephrolepis and Pinus doraiensis, Betula ermanii and Magnolia sieboldii, and high negative correlations was proved between Acer pseudo- sieboldianum and Tripterygium regelii, Weigela subsessilis and Acer tschonoskii var. rubripes, Taxus cuspidata and Acer tschonoskii var. rubripes. Species diversity(H') of investigated area was calculated 2.3015(0.9991) and this value was relatively lower than that of other subalpine forest. Taxus cuspidata trees were severely stressed and vigor-lossed and 8.22% of surveyed Tacus cuspidata trees were dead tree. Dead trees were distributed mainly in 20~60cm DBH class and a few seedlings of Taxus cuspidata were observed. To conserve Taxus cuspidata forest at Janggunbong area in Taebaeksan, intensive research, prescription on the decline of Taxus cuspidata and proper forest management were needed.

To investigate the vegetation structure of mountain ridge from Bubong to Poamsan, 16 plots$(400m^2)$ set up with random sampling method were surveyed. Three groups Quercus mongolica-Pinus densiflora community, Quercus variabilis-Pinus densiflora-Quercus mongolica community were classified by cluster analysis. Quercus mongolica was found as a major woody plant species in the ridge area from Bubong to Poamsan, and partly in lower elevation was occupied by Quercus variabilis and Pinus densiflora. High positive correlations was proved between Lespedeza maximowixcii and Pinus koraiensis, Fruxinus sieboidiana and Rhododendron mucronulatum, Acer mono and Weigela subsessilis, and relatively high negative correlations was proved between Symplocos chinensis for. pilosa and Fraxinus sieboldiana, Rhododendron mucronulatum Species diversity(H') of investigated groups were ranged $0.9066\~1.0821$, and it was relatively low compared to those of mountain ridge area of other national parks.

50-year tree-ring ${\delta}^{18}O$ chronologies (1966~2015) for principle conifer tree species (Taxus cuspidata, Pinus koraiensis, Abies koreana) and Quercus mongolica at subalpine zone in Mt. Jiri were established. The establishing of tree-ring ${\delta}^{18}O$ chronologies for each tree species were fulfilled using four trees, which showed the good result in cross-dating. In the comparisons between tree-ring ${\delta}^{18}O$ chronologies within the same tree species all tree species showed reliable results statistically (p < 0.001), and they also showed EPS higher than 0.85. In addition to, the reliable correlations (p < 0.001) were verified between tree-ring ${\delta}^{18}O$ chronologies of four tree species, as well. In the response function analysis in order to investigate the relationships between tree-ring ${\delta}^{18}O$ chronologies and corresponding climatic factors, i.e., monthly precipitation and mean temperature, T. cuspidata showed a negative correlation with May precipitation (p < 0.05) and A. koreana showed a negative correlation with April precipitation (p < 0.05). If long tree-ring ${\delta}^{18}O$ chronologies of T. cuspidata and A. koreana will be established, it will be possible to reconstruct April and May precipitation in the past when we have no the meteorological data.
