  • 본 연구는 계룡산국립공원 동학사 계곡의 식물군집구조를 파악하기 위하여 실시되었으며, 10cm$\times$10m(100$\m^2$) 조사구를 52개 설정하여 식생조사를 실시하였다. 52개 조사구는 TWINSPAN에 의한 classifi-cation 분석과 DCA ordination 분석을 통하여 소나무군집(16개 조사구), 밤나무군집(4개 조사구), 신갈나무군집(5개 조사구), 졸참나무군집(13개 조사구), 느티나무군집(4개 군집), 서어나무군집(10개 조사구)으로 나누어졌다. 6개 군집의 천이경향을 살펴보면 소나무군집, 신갈나무군집, 졸참나무군집,느티나무군집은 각 층위별 안정된 층위구조로 현상태를 유지할 것이며, 밤나무구닙은 참나무류를 거쳐 서어나무로의 천이가 진행될 것으로 판단되었고, 서어나무군집은 졸참나무와 굴참나무군집으로 퇴행천이될 것이다. 6개 군집의 Shannon의 종다양도지수는 1.2732~1.4699이었다.

  • 계룡산국립공원 동학사-남매탑구간의 산림군집구조를 분석하기 위하여 64개 조사구를 설정하고 식생구조를 실시하였다. Classification의 기법 중 하나인 TWINSPAN을 이용하여 군집분리를 시도하였으며, 그 결과 소나무 군집(I), 굴참나무-소나무군집(II), 서어나무-굴참나무군집(III), 굴참나무-졸참나무군집(IV), 서어나무-까지박달군집(V), 신갈나무-서어나무군집(VI), 느티나무-졸참나무군집(VII) 그리고 느티나무군집(VIII)의 8개로 분리되었다. 연륜분석결과 이지역의 임령은 약 60년 안팍이었으며, 단위면적(100$\m^2$)당 평균출현종수는 15.0$\pm$3.2종. 평균출현개체수는 95.7$\pm$37.3주었다. 이상의 결과를 통해 계룡산국립공원이 동학사-남매탑구간 지역은 소나무림에서 굴참나무, 졸참나무, 신갈나무림을 거쳐 서어나무, 까지박달림으로 천이가 진행될것으로 예상되었다.

  • 계룡산국립공원 연애골 계곡부(해발 170-630m)의 해발고와 사면부위에 따른 교목층과 아교목층의 산림구조를 조사하기 위하여 해발고와 사면부위에 따란 48개 조사구를 설정하였다. 계곡 정부를 제외할 때, 해발고가 높아짐에 따라 교목층의 밀도는 증가하는 반면 아교목층의 밀도는 감소하였으며, 교목층과 아교목층 전체의 밀도는 별차이가 없었다. 흉고단면적은 계곡 하부와 중부가 상부에 비하여 높았다. 해발고가 높아짐에 따라 중요치가 증가하는 경향을 보이는 수종은 산길나무, 팥배나무, 쇠물푸레 등이었으며, 감소하는 경향을 보이는 수종은 산벚나무, 졸참나무, 때죽나무, 갈참나무, 밤나무 등이었다. 사면 하부에서 갈수록 중요치가 증가하는 경향을 보이는 수종은 소나무, 신갈나무, 쪽동백나무, 쇠물푸레 드잉었으며, 감소하는 경향을 보이는 수종은 느티나무, 때죽나무, 비목나무, 고로쇠나무 등이었다. 해발고대별 종다양의 범위는 0.971~1.273이었으며, 종다양도와 종수는 계곡 중부가 계곡하부와 상부에 비하여 다소 낮았으나 균재도는 유사하였다. 계곡 정부를 제외한 해발고대간 유사도지수는 30.8~63.7%, 사면부위간 유사도지수는 69.8~79.5%로서 사면부위보다 해발고에 따른 종구성상태의 변화가 더 크게 나타났다. 수종별 중요치에 의한 Cluster 분석 결과 계곡 하부의 사면 상. 중, 하부에 위치한 때죽나무-소나무-낙엽활엽수군집, 계곡 중부의 사면 상, 중, 하부에 위치한 굴참나무-낙엽활엽수군집 계곡 상부의 상. 중. 하부에 위치한 물푸레나무-낙엽활엽수군집, 계곡 정부에 위치한 소나무-신갈나무군집 등 4개 유형군집으로 구분되었다. 종상관을 분석한 결과 느티나무, 물푸레나무, 고로쇠나무, 팽나무, 회나무 등 5개 수종간, 소나무, 쇠물푸레, 산철쭉 등 3개 수종간 유의적인 정의 상관을 보였다. 유의적인 정의 상관을 보인 느티나무, 물푸레나무, 회나무, 사람주나무 등 4개 수종 모두 소나무와 유의적인 부위 상관을 보였으며, 유의적인 정의 상관을 보인 졸참나무는 유의적인 정의 상관을 보인 물푸레나무, 사람주나무, 회나무와, 유의적인 부의 상관을 보였다.

  • This study was carried out to classify forest vegetation of the Mt. Naeyeon with phytosociological analysis of ZM school and to explain ordination of communities with CCA. The research sites were located between the northern part of Pohang-si area and the southern part of Yeongdeok-gun area. The 70 plots consisted of 253 species were investigated. The forest vegetation was classified into Quercus mongolica community, Q. variabilis community, Pinus densiflora community, Carpinus laxiflora community and Zelkova serrata community. Q. mongolica community was divided into 2 groups such asRhododendron schlippenbachii group and Euonymus oxyphyllus group and Q. variabilis community was divided into 3 groups such as Syneilesis palmata group, Lespedeza × tomentilla group and Tilia mandshurica group, and Z. serrata community was divided into 2 groups such as Carpinus cordata group and Diospyros lotus group. According to the results of CCA ordination, Q. mongolica community showed high positive correlation to altitutde and topography, whereas it showed negative correlation to bare rock. Buck Z. serrata community showed the opposite tendency to Q. mongolica community. Altitude was considered as the most important factor among 5 environmental variables in the correlation with axes.

  • The developmental process of Paracolopha morrisoni's galls on Zelkova serrata until the emergence of alatae from the galls was studied at Chonju, Korea. The galls were formed from late April to early May, 1997 and the galls began to open in early June. The length and width of galls and leaves were measured during the period from gall formation to opening. The length and width of galls have been increased until mid May continuously. The galls stopped growing at 12th of May. Fundatrices (the first generation in the gall) began to larviposit from May 15th and the second generation developed in late May. The alatae of the second generation arrived at the final stadium, that was escaped from the gall, in early June. Thus, there were only 2 generations in the gall. The close correlationship between gall growth and leaf growth suggests that leaf growth force may have a great influence on gall development.

  • This study investigated the actual vegetation and plant community structure of Geumsun valley and Weonjeok valley of Naejangsan(Mt.) National Park to provide the data for park management. As a result of analysis of actual vegetation, Quercus variabilis community(47.3%) and Quercus serrata community(17.0%) are widely distributed but Carpinus tschonoskii community(7.5%) and Zelkova serrata community(6.9%) are distributed in valley forests. Plant communities were divided into 6 communities of Fraxinus mandshurica, Carpinus tschonoskii, Carpinus tschonoskii-Platycarya strobilacea-Zelkova serrata, Zelkova serrata, deciduous broad-leaved mixture(Zelkova serrata-Lindera erythrocarpa-Acer palmatum), and Lindera erythrocarpa-Cornus walteri according to the analysis of TWINSPAN of classification using 20 plots($400m^2$). Geumseon valley is composed of boulder stone area of average slope $20^{\circ}$, and there were distributed Fraxinus mandshurica community of 86 years old, Carpinus tschonoskii community in age from 56 to 79, and Carpinus tschonoskii-Platycarya strobilacea-Zelkova serrata community in age from 48 to 71. Weonjeok valley is composed of boulder stone area of average slope $11^{\circ}$, and there were distributed Zelkova serrata community in age from 52 to 71, deciduous broad-leaved mixture community in age from 49 to 70, and Lindera erythrocarpa-Cornus walteri community in age from 43 to 51. Ecological succession of each community was predicted to maintain same state. The Shannon's species diversity showed from 0.8220(Fraxinus mandshurica community) to 1.3850(Carpinus tschonoskii community) per unit area of $400m^2$.

  • The purpose of this study is to examine what people in Korea recognize the cultural symbolism and the planting patterns of 'Guǐmok', pagoda tree(Sophora japonica). The species planted in the 'Guǐjeong' was empirically investigated and analyzed to determine which species of pagoda tree or Zelkova tree(Zelkova serrata) was taken through literature surveys, field surveys, and interviews with persons. This 'Guǐjeong' was combined to track how the culture of the 'Guǐmok' planting introduced in China was ultimately accepted and transformed in Korea. In this study, we tried to analyze the meaning implicit in the mystery while checking the distribution of the mystery and the form of the mystery, the name of the pavilion and its relevance to the contrast medium. Essentially, the trees that govern the characterization of the nectar plant, regardless of the region, are considered to be a pagoda tree, which is considered an internal factor in which the pagoda tree culture was not completely transformed into a zelkova tree. It was recognized throughout the Joseon Dynasty that the species representing 'Prime ministers(三公)' was judged from all the Joseon Dynasty periods, based on the builder of Guǐjeong's Aho(雅號) and Dangho(堂號). It was confirmed that the tree was very likely to be planted in place of the painting tree. But now is selectively zelkova tree is in accordance with the preparation of planting site conditions and areas on behalf of the Change is very high probability that is planted. Cultural variables that led to the cultural transformation of the 'Guǐmok' seem to have been deeply involved in the geographical space of China and Korea, Confucian practices of the Choson society, comings and goings and letter bridge, and network strength with China through the book spread. In addition, the culture of 'Guǐmok' is presumed to have led to cultural custom of the upper class, not the whole class, in the Yeongnam region, it can be said that the independent adaptation to act to recognize 'Guǐmok' as a pagoda tree, that is a Sophora japonica, has occurred very strongly. The difference between the cultural areas of Yeongnam and non-Yeongnam is also considered to be an internal factor that has played a major role in the cultural transformation of planting of 'Guǐmok'.
