This study was conducted to investigate the population structure and dynamics of the Picea jezoensis stands which are located in Mt. Gyebangsan and surveyed from March to October 2012. Results showed that the diameter class distribution of P. jezoensis presented a reverse J-shaped distribution pattern with 32 trees less than 10cm DBH, 20 trees in 10~30 cm DBH, and 11 trees more than 30 cm DBH. It showed seedlings and saplings of P. jezoensis seem to prefer areas with more sun light or with open upper layer. It was also observed that P. jezoensis preferes areas with organic soils and abundant water such as areas around stumps. Also, occurrences of P. jezoensis stands were analyzed through annual mean radial growth of the trees. And the results showed that the growth naturally or artificially occurred approximately on the years 1854, 1915, 1918, 1993 and 2002 years. Most of the gap-makers were classified as standing dead type with 23 individuals (45.1%).

This study was conducted to investigate the effects of adjacent stand on the invasion of Robinia pseudoacacia plantations. The results were as follows. 1) Robinia pseudoacacia tended to invade into all directions regardless of the kinds of adjacent stands. But it was estimated that the invasion of Robinia pseudoacacia into adjacent stands could be very difficult, if the layer structure of adjacent stands were well developed. Whereas, it was estimated that Robinia pseudoacacia more rapidly intruded into adjacent stands, if adjacent stands were opened and bared. 2) Robinia pseudoacacia tended to invade into all aspects regardless of the kinds of vegetation units in the adjacent stands. But the dominance class of Robinia pseudoacacia in the adjacent stands showed a little differences among the vegetation units. The dominance class of Robinia pseudoacacia in Quercus aliena community and Quercus serrata community showed low level as +∼2, while the dominance class of Pinus densiflora community, Pinus rigida community, Quercus variabilis community and Quercus acutissima community represented high level as 1∼4. Also the dominance class of Isodon inflexus subgroup among three subgroups of Pinus densiflora community showed the lowest level as + ∼2.

윤충원,홍성천,Yun, Chung-Weon,Hong, Sung-Cheon 한국생태학회 2000 Journal of Ecology and Environment Vol.23 No.3

금강송림의 식생단위와 환경과의 상관관계, 종조성, 종다양도, 종간결합 등 생태학적 특성들에 대하여 정량적으로 연구하였던 바 다음과 같이 요약되었다. 1) CCA 방법으로 분석한 결과 주로 지형, 해발, 유효인산, 마그네슘 등의 환경요인들이 높은 상관관계를 보여주고 있었다. 꼬리진달래군락은 해발이 논고 사면상부나 능선부쪽 지형으로 갈수록 더 많이 분포하는 경향이었고, 마그네슘과 칼슘이온의 농도는 낮은 입지에 주로 분포하였다. 산앵도나무군락은 칼슘, 마그네슘의 이온농도가 높은 입지에 분포하는 경향이었고, 사면중상부와 능선부로 갈수록 많이 분포하는 경향이었다. 2) 중요치 분석결과 각 지역의 교목층과 아교목층에서 중요치가 높게 나타난 종은 금강송, 신갈나무, 굴참나무, 졸참나무, 물푸레나무 등이었으며, 관목층에서는 소광리 지역이 다른 지역에 비해 금강송의 중요치가 높게 나타났다. 즉, 소광리의 금강송 임분이 천연갱신이 가장 잘 되고 있음을 반영하였다. 3) 종다양도지수를 보면 울진이 0.6622로 가장 낮았고, 기타지역은 대부분 0.7내외로 나타났으며, 식생단위별 종다양도 지수는 당단풍군락이 높게 나타났다. 4) 소광리지역은 울진과는 군락유사도의 차이가 낮게 나타났으며, 기타지역간에는 군락유사도가 0.6이상으로 높게 나타났다. 5) 종간결합관계 분석 결과 크게 두 개의 그룹으로 구분되었다. 한 그룹은 식물사회학적 분석에서의 표징종군과, 또 한 그룹은 식별종군과 거의 일치하였다. The objectives of this study were to classify quantitatively vegetational types of P. densiflora for. erecta forest. The results were summarized as follows. 1) According to the canonical correspondence analysis(CCA), variables such as topography, altitude, available P/sub 2/O/sub 5/, and Mg/sup 2+/were highly correlated on three axes. Based on the correlations between vegetation units and environmental factors, Rhododendron micranthum community tended to be more distributed in the such situations of high altitude, upper topography, high C/N ratio, low level of Mg/sup 2+/and Ca/sup 2+/. Vaccinium koreanum community tended to be more distributed in the such conditions of high altitude, upper topography, high level of Ca/sup 2+/and Ma/sup 2+/. 2) According to the results of importance value analysis, Tree layer and Subtree layer in study areas showed high Ⅳ along with P. densiflora for. erecta, Quercus mongonlica, Q. variabilis, Q. serrata, Fraxinus rhychophylla and shrub layer indicated that Ⅳ of P. densiflora for, erecta in Sokwang-ri area was higher than those of the other areas. Therefore, it was considered that P. densiflora for. erecta forest of Sokwang-ri area could be naturally regenerated. 3) According to results of species diversity, the species diversity of Uljin region showed the least low value as 0.6622, other regions appeared about 0.7. In the diversity by vegetation types, Acer pseudosieboldianum community showed high value. 4) According to the analysis of community similarity, Sokwang-Ri region was lowly correlated with Uljin region, while the index among the other areas appeared above 0.6. 5) According to the analysis of interspecific association, it was divided into 2 groups. The species of first group were mainly involved in character species, and the species of second group were involved in differential species groups.

이병천,윤충원,Lee, Byung-Chun,Yun, Chung-Weon 한국생태학회 2002 Journal of Ecology and Environment Vol.25 No.3

내연산의 삼림식생을 대상으로 ZM식물사회학적 방법에 의해 군락단위 및 그 하위단위를 분류하고, 분류된 각 단위와 환경사이의 상관관계를 서열법으로 해석하여 내연산 산림식생관리를 위한 기초자료를 제공할 목적으로 본 연구를 수행하였다. 군락단위는 신갈나무군락, 굴참나무군락, 소나무군락, 서어나무군락, 느티나무군락이 구분되었고, 하위단위는 신갈나무군락에서 철쪽꽃군과 참회나무군, 굴참나무군락에서 우산나물군, 털조록싸리군 및 찰피나무군, 느티나무군락에서 까치박달군과 고욤나무군이 각각 세분되었다. 따라서 내연산 일대의 산림은 5개군락, 7개군으로 총 9개의 식생단위로 분류되었다. CCA 방법으로 식생과 환경사이의 상관관계 분석 결과 내연산 지역의 식생단위는 해발과 가장 높은 상관관계가 있는 것으로 나타났다. 신갈나무군락의 철쪽꽃군과 참회나무군은 해발고와 지형이 높은 곳과 노암율이 낮은 곳에 각각 분포하는 경향이었다. 한편 느티나무군락은 신갈나무군락과 역의 관계로 나타났다. 앞으로 산림식생관리시 특히 계곡림에 대해서는 교목층의 우점종들이 상관적으로 이질적인 모습을 하고 있더라도 하나의 관리단위로 고려되어야 할 것으로 판단되었다. 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 as Rhododendron schlippenbachii group and Euonymus oxyphyllus group and Q. variabilis community was divided into 3 groups such as Syneilesis palmata group, Lespedeza$\times$tomentilia 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 altitude and topography, whereas it showed negative correlation to bare rock. But 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 Mt. Cheongok is located at the northern part of Kyungsangpookdo from 37°00` 00`` to 37°05` 00`` latitude and from 128°55` 00`` to 129°00` 00`` longitude. The altitude of the summit is 1,276.5m. This study was carried out to classify forest communities by the methods of Zurich-Montepellier schools. And, it also might be useful for selection of plant species, forest conservation, and prompting vegetation succession. The forest vegetation in Mt. Cheongok was classified into 12 communities, 4 groups, and 4 subgroups. Rhododendron micranthum subgroup of Pinus densiflora for. erecta community and Fraxinus mandshurica community were not found in cool temperate forest, southern zone yet. According to the coincidence method, Pines densiflora for. erecta community was mainly distributed from altitude 450m to 1,100m and from upper slope to ridge, and Quercus mongolica community was dominanced in the range of over altitude 700m. Pinus densiflora for. erecta community, distributed in upper slope and ridge, is judged to be maintained in the future. But Pinus densiflora for. erecta community, distributed in below middle slope, is judged to be changed into deciduous hardwood forest.
