This study investigated the structural characteristics of Taxus cuspidata communities on Mt. Hambaek. The vegetation consisted of 9 species in the T$_1$(tree) layer, 35 species in the T$_2$(subtall tree) layer, 28 species in the S(shrub) layer, and 69 species in the H(herb) layer. The dominant species of the T$_1$ layer was Taxus cuspidata and that of the T$_2$ layer was Acer tschonoskii var, rubripes. The dominant species of the S layer was Tripterygium regelii, and the dominant species of the H layer was Pseudostellaria palibiniana. The diameter distribution of the dominant five species in the T$_1$ and T$_2$ layers indicates that these Taxus cuspidata forests may be gradually dominated by Quercus mangolica and by Tripterygium regelii. The composition of biological type was Ph-D$_1$-R$_{5}$-e.

This study was carried out to investigate the structural characteristics of Taxus cuspidate communities in Mt. DuckYoo. The vegetation was consisted of 20 species in the T$_1$(tree) layer, 26 species in the T$_2$(subtall tree) layer, 26species in S(shrub) layer, and 56 species in the H(herb) layer. The dominant species of Mt. Duckyoo was Taxus cuspidata in the T$_1$ Layer, Acer tschonoskii var. rubripes in the T$_2$ Layer, Tripterygium regelii and Acer tschonoskii var. rubripes in the S Layer and Sasa borealis in the H Layer. According to the diameter distribution of high ranking five species in T$_1$, T$_2$ layer at natural Taxus cuspidata communities, these forests may be gradually replaced by Quercus mongolica, Tripterygium regelii. The composition of biological type was Ph-D$_1$-R$\sub$5/-e.

In this study, the sustainability of Abies nephrolepis in the presence of Tripterygium regelii was analyzed. To accomplish this, a field survey of140 stands was conducted. Based on the presence or absence of T. regelii, as well as the layer in which it was present (where appropriate), the type of T. regelii presence wasclassified as follows: TP type, indicating the presence of T. regelii in the tree and sub-tree layers; SP type, indicating its presence in the shrub layer; and A type, indicatingits absence from all layers. The indicator species analysis revealed T. regelii to be an indicator species of the TP type and SP type. The MRPP test was used to examine the differences among the types. Moreover, the seedling and DBH class analysis indicated there to be a difficulty in terms of the status competition, as the number of young trees generated by A. nephrolepis was the lowest in the TP type. The findings of this study enhanced our understanding of the vegetation structure of A. nephrolepis, thereby contributing to efforts concerningits conservation and management.

본 연구는 청옥산 산림유전자원보호구역을 대상으로 총 49개의 고정방형구를 설치하여 식물사회학적 방법으로 산림군락분류와 임분특성을 분석하였다. 그 결과 총 9개의 식생단위로 분류되었으며 군락단위로는 신갈나무군락, 잣나무군락, 일본잎갈나무군락, 독일가문비나무군락으로 분류되었다. 신갈나무군락은 소나무군, 철쭉군, 고로쇠나무군, 미역줄나무군으로 세분되었으며, 고로쇠나무군은 박달나무소군과 고로쇠나무전형소군으로, 미역줄나무군은 애기감둥사초소군과 미역줄나무전형군으로 세분되었다. 9개의 식생단위의 층위별 중요치 분석결과를 보면 교목층에서 신갈나무가 32.2% 가장 높게 나타났으며 잣나무(10.1%), 소나무(10%), 일본잎갈나무(9.1%) 순으로 나타났고, 아교목층에서는 신갈나무 (18.9%), 당단풍나무(11.7%), 물푸레나무(8.9%), 잣나무(7.2%) 등이 높은 값으로 분석되었다. 관목층에서는 철쭉(12.2%)와 당단풍나무(8%)가 높게 분석되었으며 다른 수종들은 10% 미만의 값을 가졌다. 초본층에서는 조릿대(8.5%), 산숙국(6.6%)등이 높게 나타났다. 식생단위별 종다양성지수를 보면 식생단위 8인 일본잎갈나무군락이 1.76로 가장 높았으며, 박달나무소군 1.73, 소나무군 1.72, 철쭉군 1.71 순으로 분석되었다. 우점도는 모든 식생단위에서 0.2 이하로 다수의 종이 우점하는 것으로 나타났다.

To investigate and to compare the structure of Picea jezoensis forests at Chunwangbong area in the Jirisan National Park, 33 plots(400) were set up by a random sampling method. Dead individuals of Picea jezoensis trees were 15.6%, these were observed mainly in the upper-layer trees. A few seedlings of Picea jezoensis were found in this investigation area. This result indicates that Picea jezoensis might be gradually decreased in the future. Picea jezoensis stands were classified into two major groups by cluster analysis. There were strong positive correlations between Syringa reticulata and Acer pseudosieboldianum, Tripterygium regelii, Quercus serrata; Betula ermani and Lonicera maackii; Euonymus macropterus and Acer ukurunduense; Acer pseudosieboldianum and Tripterygium regelii, and relatively weak negative correlations were showed between Picea jezoensis and Abies koreana; Betula ermani and Acer ukurunduense; Acer pseudosieboldianum and Tripterygium regelii. Species diversity index(H') of investigated groups ranged from 1.0000 to 1.3010.
