On the Distribution of Beech(Fagus, Fagaceae) and Beech-Dominated Forests in the Northern Hemisphere
Yim, Yang-Jai ;
The Korean Journal of Ecology, volume 6, issue 3, 1983, Pages 153~166
The distribution of beech species (Fagus) and beech-dominated forests along climatic gradients in the Northern Hemisphere was studied by use of taxonomic and ecological literature. The genus Fagus as a whole occurs over the range of 4.5 to 20.0。C mean annual temperature and 600 to 1000 mm in lower limit, mean annual precipitation. At the higher end of the temperature range, beech occurs in zones with relatively high growing-season precipitation. Edaphically, beech species and beech-dominated forests tend to occur on mesic, moderately fertile sites. Beech-dominated forests occur in a limited portion of the climatic range of the genus with sensitive responses to other environmental factors. The distributional range of beech-dominated forests on a global scale depends more on climatic factors and geological events than on soil conditions or other factors, summarizing the facts obtained by many researchers on beech dominated forests.

Kim, Cheol Soo ; Tae Gon Song ;
The Korean Journal of Ecology, volume 6, issue 3, 1983, Pages 167~176
Species composition, life form, biomass and soil properties of the halophyte communities were investigated from July to September, 1982. At the reclaimed land of Sanho-ri, sand dune of Jido, salt marsh of Suncheon Bay, and Somjin River estuary of Baealdo, species numbers were 26, 14, 13 and 7, dominant species were Salicornia herbaceae, Carex pumila and Suaeda japonica, respectively. Species composition of the 4 investigated areas was 13 families, 25 genera and 39 species, and of them, 10 families, 21 genera and 24 species were attributed to halophytes. Out of 22 life forms, the representative for Jido was
and those for the other sites were Th-G4-R5-e. Above ground biomass of all species for Sanho-ri, Jido, Suncheon Bay and Baealdo were 441.3, 202.0, 150.7 and 353.3 g.dw/m2 and the ratios of above ground biomass halophytes to all species were 93.5, 92.7, 90.8 and 100%, respectively. The leading dominant species formed a continuum according to the salt gradiant. The similarity between Baealo and Suncheon Bay was relatively high, and Jido was quite different from the others in species composition. Aster tripolium was stenohaline and appeared at the low salt concentration, but Suaeda maritima and Suaeda asparagoides were duryhaline and occured at the relatively high salt concentration.

The Korean Journal of Ecology, volume 6, issue 3, 1983, Pages 177~186
Vegetation types and their standing crop in the sand dune on the south coast of Korea was investigated by the method of Curtis, J.T. and McIntosh, R.P. (1951). The relationship between vegetation types and environmental factors was also analyzed. The dominant species in the vegetations of the south coast sand dune were Carex pumila, Calystegia soldamella, Imperata cylindrica var. koenigii, Vitex rotundifolia, Ixeris repens, Carex kobomugi, Zoysia macrostachya. The species density in the sand dune vegetation increased with the distance from the coast, psammophyte and rhizome psammophyte decreased with the distance from the coast but other plants increased. The standing crop of the sand dune vegetatiion was average
. An individual standing crop of Vitex routundifolia and Carex kobomugi varied with the curve of secondary degree. The salt content of the sand dune soil from 2.95 to 11.78 mg %, and it was not significant differences among stands, but it was varied with the distance form the coast. Negative relationship between warmth index and aboveground standing crop was found and the formula y=283.8886 - 2.4910X could be estimated.
The Secondary Vegetation of the Burned Area of a Mountain in Dangji-Dong
Kim, Woen ;
The Korean Journal of Ecology, volume 6, issue 3, 1983, Pages 187~197
This report is a series of the investigation of the secondary vegetation and succession at the forest fire area in Dangji-Dong of Kyungsang-pookdo province. The forest fires occurred on April 8, 1982. This investigation was carried out from June 18, 1982 to May 29, 1983 once in each season. Before to fires, the Pinus densiflora was dominant and the woody plants of understory were mainly composed of the Quercus serrata, Q. dentata, Lespedeza maritima and L. macimowiczii. Compared with the florstic composition between the unburned and burned areas after the fires, the floristic composition of unburned area comprises: 79 families, 194 genera, 223 species, 26 varieties and 6 formae (255 kinds of vascular plants). The index of similary shows 0.77 (S
renson:1948) in this area. The analyses of the life-form compositions in the unburned and burned area show 32.9% and 29.3% in dormancy form (H), 42.4% and 37.7% in disseminule form(
), 80.8% and 82.2% in radicoid form (
), and 57.7% and 61.8% in erect form(e) respectively. The biological type shows H-
-R5-e, which is common in both areas, and erect form is generally prevailing in these communities.
A Study of the Matter Production and Decomposition of Quercus serrata and Carpinus Iaxiflora Forests at Piagol in Mt. Juri
Chang, Nam-Kee ; In-Ja Kim ;
The Korean Journal of Ecology, volume 6, issue 3, 1983, Pages 198~207
The dry-matter production, the litter decomposition and the nutrient cycle were studied on Quercus serrata and Carpinus laxiflora forests at Piagol in Mt. Jiri. With the growth curves of the annual ring, the time schedules for the maximum productivities and maximum yields were measured. In Q.serrata forest, the maximum productivity was 11.36 tons
at the 49th year and the maximum yield was 115.78 tons
at the 73th year, and in C. laxiflora 7.24 tons
at the 35th year and 82.5 tons
at the 53th year, respectively. The maximum productivities and the maximum yields of the leaves, stems and roots of the trees were calculated. The contents of nitrogen, phosphorus, potassium and organic carbon were measured.. While inorganic materials were the most abundant in the leaves, organic materials in stems. The maximumproductivities and the maximum yields of the constituents of the trees were calculated, assuming that the constituents of the trees increase allometrically. The decomposition rates were as follows: k = 0.301 for Q.serrata forest, and k = 0.364 for C. laxiflora forest. The litter of the former was decayed more slowly than that of the latter. The halftimes for decomposition were 3.2 and 1.9 years, respectively.

Kim, Jong-Hong ; Chang, Seok-Mo ;
The Korean Journal of Ecology, volume 6, issue 3, 1983, Pages 208~226
The vegetation of Odongdo island was surveyed over twenty-nine times from April, 1982 to August, 1983. This island is located at 127。46'05'∼127。39'37'E. longitude and 34。40'20'∼34。48'14'N. latitude. The vegetation of this island consisted of 94 families, 261 genera, 314 species, 53 varieties and 6 formae. And among them were 170 species of woody plants and 203 species of herbs. The community of evergreen broad-leaved trees comprised a total of 44 species including Sasa coreana Nakai and camellia japonica L. and the distribution of evergreen broad-leaved trees was good in this island as a whole. Sasa coreana Nakai, Castanopsis cuspidata var. sieboldii Nakai, Ficus erecta Thunb., Ficus nipponica Fr. et Sav, Stauntonia hexaphylla (Thunb.) Decne, Cinnamomum japonicum Sieb., Machilus thunbergii S. et Z., Lozoste lancifolia (S. et Z.) Bl., Ilex intergra Thunb., Camellia japonica Thunb., Hedera rhombea Bean and Ardisia japonica Bl. etc. in this island were autochthonous flora and their preservation is required.

This research was made over drought resistance and optimum soil moisture needed with Plantago asiatica L. as the material by means of making out the process of its growth under different soil moisture contents. The soil used for the experiment was a mixture of vermiculite and c-layer soil, and the process of growth was compared with each other controlling its soil mositure as: 7%, 15%, 30%, 45%, and 60%. In 7% range of soil moisture which was of low content, the increase of growth was neither significantly indicated nor any permanent seeding done. In view of this phenomenon, Plantago asiatica L. appeared to be highly drought-resistant. It was found rising at 30% range and reaching the optimum state at 45% range and falling down at 60% range range. In viw of this fluctuation indicated above, the optimum soil moisture content needed for the growth of Plantago asiatica L. is thought to be between 30% and 60%. It is thought the number of seed per capsule is not affected by the soil moisture content. It is expected an ecotypic variation by the soil moisture content will bring forth upon Plantago asiatica L.
