In this study, the forest vegetation of Jirisan National Park were classified into 20 communities, 3 subcommunities by the Z-M method. In the analysis of environmental factors, the organic matter and total nitrogen had the highest correlation on the subalpine forests. among them Picea jezoensis community showed the highest, Betula ermanii community, Taxus cuspidata community, Pinus koraiensis community, Abies nephrolepis community and Abies koreana community were represented in order. the K, Mg, Ca had correlation on th montane forests; Quercus mongolica community, Quercus serrata community, Stewartia pseudocamellia community, Pinus densiflora community, Quercus variabilis community were in order. the total nitrogen, electrical conductivity and organic matter had the highest correlation of the montane ravine forests; Fraxinus mandshurica community, Abies holophylla community, Betula costata community, Cornus controversa community and Carpinus laxiflora community were in order.

In order to study the successional trend and the heterogeneity of forest community, we investigated DBH frequency distribution of dominant tree species and the changes of several community indicies including ${\beta}-diversity\;({\beta}_t)$ along a belt transect in Mt. Yongam, Kwangnung Experimental Forest, which has been preserved for about 530 years. Quercus serrata, Carpinus laxiflora, and C. cordata were the three dominant species and their DBH frequency distribution showed a reverse J-shaped form, so these species seem to maintain by themselves. Dominancediversity curve had a lognormal distribution. d and H'for pooled quadrats were 0.13 and 1.09, respectively, but these indices within each quadiat varied with the range of 0.13 to 0.57 and 0.5 to 1.09, respectively. The value of ${\beta}_t$ along the belt transect ranged from 0.14 to 0.42. These results suggest that this forest community is in the stable climax stage but the components experience a heterogeneous microsuccession.

Losses in the dry weight of leaf litter from six tree species were studied during 16 months on the forest floor in temperate deciduous forest of Mt. Cheonma in the vicinity of Seoul in Korea by using litter bag method. The decomposition rate of each leaf litter varies with each species. After 16 months elapsed, the leaf litter of Acer pseudo-sieboidianum showed the highest decomposition constant (0.82) as Olson´s decomposition constant, while that of Pinus densiflora showed the lowest decomposition constant (0.33). The decomposition constant of Quercus mongolica, Q. serrata, Betula ermani and Carpinus laxiflora showed 0.43, 0.37, 0.66 and 0.75, respectively. The decomposition constant of leaf litter was considered with temperature and precipitation which accumulated daily during each term of litter bag collection. The decomposition constant of leaf litter showed closely positive correlation with daily accumulative temperature and precipitation. The relationships between decomposition constant and the daily accumulative temperature and precipitation at each period of litter bag collection were analyzed through multi-regression analysis. The correlation coefficients as a result of multi-regression analysis in Q. mongolica, Q. serrata, P densiflora, B. ermani, C. laxiflorais and A. pseudo-sieboldianum were 0.83, 0.81, 0.69, 0.77, 0.77 and 0.62, respectively. The precipitation showed higher effect, about 10 times, on the leaf litter decomposition than the daily accumulative temperature.

This paper contains the results obtained by ecological investigation of ilora in Muie Island of Incheon Harbor in the xestern coast in Korea. 14 varieties, 1-27 species, 57 families and 142 genera of Tracheophyta were recorded by field investigations conducted over three times in May and July, 1976 and August, 1980. The flora of this island showed a plant community predominated by Pinus densiflol-a grown in miggle with Carpinus laxiflora, Quel-cus serrata and Rhododendron muucronulatum. Generally, the number of plant species was scarce, but it was an unexpected result that such remote mountainous plants as Lysinzachia clethrozdes, Sy7zeilesis palnzata and Lilzunz disttcum etc. were encountered in a wood surrounding Seohwang-dang, the shrine of a tutelary deity, on 126-Meter Hill at the northern end of the island. There also countered in Hoyong mountain valley were deciduous broad-leaved forests without pine tree which mainly consisted of Prunus leveillea7za, Fraxinus rhynchophylla, Platycarya strofilada, Quercus serrata. Quercus acutissznza and Acer mono. In addition, herbaceous plants, such as Syneilesis palmata, Codonopsis lanceolata and Lysi\ulcornerna barystnchy were grown as the undergrowth of these forests. Drosera rotundifolio, an unlooked-for plant, . appeared in the middle of the eastern coast of the island. Camellia japo7tica was grown spontaneously in Deogjeog Island 261cm southwest from the island, while no evergreen broa-leaved tree could be located except 2 species of Vztex rotztndifolia and Euo~zymus japonrca. It may be considered that such simple flora of this island compared with that of land is attributed to the fact that the formation of the former took place in the period far latter than that of the latter.

This study was conducted to analyze oribatid mites communities in deciduous forests in Namsan and Kwangreung on which different levels of environmental stresses might press, and to select potential condidate of biological indicator species. In overall, pH was lower in soil than in litter layer. Also soil pH, total nitrate content and soluble sulfate content were significantly higher in Namsan than in Kwangreung (p<0.05). The flora in Namsan and Kwangreung deciduous forests were dominated by Quercus mongolica, and Carpinus laxiflora respectively. It indicated that Namsan was in the lower stage of the floral succession. The number of species of oribatid mites was significantly higher in Kwangreung (39 families, 65 genera and 114 species) than in Namsan (32 families, 53 genera and 89 species) (p<0.05). Common species found in two regions were 77 species. Mean density of oribatid mites was 1.8 times higher in Kwangreung than in Namsan and this difference came mainly from litter layer. Among correlation analyses between environmental factors and oribatid mites density and species number, only density was negatively correlated with fresh litter depth in Namsan litter layer (r=-0.89, p<0.05). The pH which was considered to affect distribution of oribatid mites didn't show significant results.

증산은 물이 기공을 통해 대기 중으로 이동하는 과정으로, 지표면의 물은 상당부분 증산을 통해 대기 중으로 이동한다. 에디공분산, 수분 수지 측정법 등의 증산량을 측정하는 방법이 있지만, 수종 및 임분의 구성 요소별 증산량의 차이를 비교하기 위해서는 개체목 증산량 측정이 필요하다. 개체목 증산량을 측정하기 위해 수액의 온도차를 이용한 수액류 측정법을 가장 널리 이용하고 있지만, 넓은 범위의 지역을 장기간 조사하기에 한계가 있다. 따라서 큰 공간적 규모에 대해 수액류 및 증산량에 대한 연구를 하기 위해서는 각 지역별로 측정한 데이터의 공유가 필요하다. 본 연구팀은 태화산 학술림에서 열손실탐침법을 이용하여 2011년부터 잣나무(Pinus koraiensis) 18본, 2013년부터 갈참나무(Quercus aliena) 16본을 대상으로 수액류를 측정하고 있으며, 광릉수목원에서도 열손실탐침법을 이용하여, 2013년부터 전나무(Abies holophylla) 18본, 졸참나무(Quercus serrata) 7본, 서어나무(Carpinus laxiflora) 3본, 까치박달(Carpinus cordata) 3본을 대상으로 수액류를 측정하고 있다. 구례 지리산 조사지에서는 열 파동법으로 2018년부터 산벚나무(Prunus sargentii), 낙엽송(Larix kaempferii), 2019년에는 추가로 상수리나무(Quercus accutisima), 소나무(Pinus densiflora), 물푸레나무(Fraxinus rhynchophylla)를 대상으로 수액류를 측정하였으며, 2020년에는 편백(Chamecypans obtuse), 잣나무(P. koraiensis), 자작나무(Betulla platyphylla), 전나무(A. holophylla), 곰솔(Pinus thrunbergii)을 대상으로 수액류를 측정하고 있다. 우리나라 산림의 수액류 데이터를 더욱 활발하게 공유하여 국내 산림생태계에서 개체목과 임분의 수액류와 증산의 환경민감성 등 다양한 연구에 기여할 것으로 기대한다.
