The study was conducted to investigate the differences in carbon storage of Quercus mongolica stands with respect to latitude and altitude in Korea. Study sites were located in Mt. Joongwang, Pyeongchang-gun, Gangwon-do (altitudes 1,300 m, 1,000 m, and 800 m), Mt. Taehwa, Gwangju-si, Gyeonggi-do (altitude 350 m), Mt. Wolak, lecheon-si, Chungcheongbuk-do (altitude 300 m), Mt. Baekwoon, Gwangyang-si, Jeollanam-do (altitude 800 m), and Mt. Halla, Jeju-do (altitude 1,000 m). Total carbon storage and annual carbon storage of Q. mongolica stands were 85-210 tonC/ha and 7.2-10.6 tonC/ha, respectively. Lower latitude (NE) stands of Q. mongolica showed more carbon storage and annual carbon storage than higher latitude stands. Carbon storage and annual carbon storage of Q. mongolica stands were increased in low altitude. Carbon storage of Q. mongolica stands was higher in the northern aspect than in the southern aspect. However, there were no significant differences in annual carbon storage between the aspects.

With the species composition table, the forest community of Mt. Yeonginsan were classified into Quercus mongolica community, Pinus densiflora community, and Quercus acutissima community. The importance value of the study community was 73.55, 36.28, 29.87, 25.07, 24.88, and 21.25 in Quercus mongolica, Quercus serrata, Pinus densiflora, Pinus rigida, Larix leptolepis, and Quercus acutissima, respectively. According to breast diameter analysis, the importance value of Quercus mongolica, Quercus acutissima and Quercus serrata continuously increase.

충북 제천시 소재 월악산 문수봉의 신갈나무림에서 gap연령이 다른 3개 지소와 성숙림인 1개 지소로 나누어 gap내 신갈나무의 재생과정을 밝혀 다음과 같은 결과를 얻었다. 식생조성은 gap형성 초기 에 관목층에서는 조록싸리, 물푸레나무, 미역줄나무, 신갈나무, 국수나무 등의 우점도가 높았다 특히, 관목층 전체를 볼때 gap형성 초기에는 개체수가 상당히 많으나 gap 연령이 증가할 수록 교목층을 형성 할 수 있는 신갈나무와 물푸레나무 등의 기저면적의 증가에 의한 피음으로 관목층의 개체수는 감소하였다. gap내에는 어린 개체가 많고 점차 감소하는 역 J자형의 분포를 나타내고 gap 연령이 증가하면서 gap내에서 급속한 성장으로 교목층을 형성하는 신갈나무의 피음에 의해 부분적으로 고사된 개체가 나타나는 것 을 볼 수 있.었다. 성숙림 에서는 어린 개체가 거의 없었으나 수령이 130년 이상인 개체가 주로 나타났고 이 들 중 한개 또는 그 이상의 개체가 어떤 교란요인에 의해서 Gap이 형성되면 이곳에 어린개체가 침입되어 재생이 이루어질 것으로 생각된다. 본 신갈나무림은 gap형성 후 gap 내에 침입한 신갈나무가 교목층을 형성하는 연령인 약 35∼40년 이후 부터 수령이 130∼330년 되는 성숙림까지 다른 신갈나무 유묘의 침입은 없지만 다른 수종으로 대치되는 것이 아니라 성숙림의 gap형성에 의해 불연속적인 재생으로 계속 유지되는 것으로 생각된다.

Eighteen kinds of medicinal edible herbs, which are nontoxic and has been widely used in traditional folk medicine, were extracted and antimicrobial activity of the extracts was investigated against various foodborne pathogens or food poisoning microorganisms. Among them, the ethanol extract of Quercus mongolica showed the strongest antimicrobial activities against Gram positive and Gram negative bacteria and followed by Quercus aliena and Quercus dentata, respectively. Thus, further study was conducted to determine the antimicrobial activity of Quercus species extracts. The plants were extracted with ethanol, methanol and water, respectively. The ethanol, methanol, and water extracts of Quercus mongolica leaf showed 10~21 mm inhibition zone against Gram positive and Gram negative bacteria at two thousand $\mu\textrm{g}$ per disc, but little antimicrobial activity was observed against fungi and yeast. The minimal inhibitory concentrations (MIC) of the ethanol extract of Quercus mongolica leaf was 250$\mu\textrm{g}$/mL against Bacillus cereus. Salmonella typhimurium, and Pseudomonas aeruginosa and 62.5~125 $\mu\textrm{g}$/mL against Staphylococcus aureus and Listeria monocytogenes, respectively.

For the establishment of district planning in natural parks, vegetationin the most significant point. Consequently, district plan should be made basically under phytosociological investigations. The purpose of this paper is to conserve vegetation in the district planning at natural park(Nam Han San Sung provincial natural park). The result of vegetation survey are as follows : As an actual vegetation 13 communities are recognized. Those are Quercus mongolica-Carpinus laxiflora community, Quercus mongolica-Rhododendron schlippenbachii community, Quercus serrate community, Betula platyphylla var. Japonica community, Quercus dentata community, Quercus mongolica-Pnuus densiflora community, Quercus acutissima community, Robinia pseudo-acacia community, Alnus hirsuta community, Castanea crenata community, Quercus variabilis community, Pinus densiflora community, Pinus rigida community, weed community on cultivated land(Form land), Larix leptolepis reforested land, cut over area and non-vegetation area. The grade of vegetation naturalness was divided into five degrees by characteristics of actual vegetation. I intended to make zoning plan for protection of vegetation with a special attention to the grade of vegetation naturalness and I discussed the necessity of the improvement of existing district plan. District plan was proposed as Fig. 5.

Distribution of size class, population regeneration and changes in the population structure of Quercus mongolica were studied from 1994 to 1999 in Mt. Jumbong (128°27' E, 38° 04' N) of Mt. Sorak National Park and Biosphere Reserve in central Korea. Three 20m × 20m permanent quadrats were set up at the elevation of 900m. The vegetation of the study site was dominated by Quercus mongolica and Acer pseudosieboldianum, but little change was observed in the community structure from 1995 to 1999. Most mortality in the study site was observed in small trees of A. pseudosieboldianum and Tilia amurensis. Mean annual growth in dbh (diameter of breast height) of Q. mongolica for 4 years was only 0.09cm, and no ingrowth of saplings (dbh < 2.5cm) into tree class was observed during the study period. Among the 21 Q. mongolica trees studied in the permanent quadrats. all the smaller trees (dbh < 30cm) were established in 1920 ∼ 1950, while many bigger trees (with 40cm < dbh < 80cm) were established in 1750 ∼ 1800, indicating that its establishment was episodic. Distribution of dbh classes among Q. mongolica trees shows that smaller trees were poorly represented, and no saplings of Q. mongolica occurred in the permanent quadrats studied, indicating that currently Q. mongolica is not regenerating well in the study site. Total seed production of Q. mongolica in 1994 was estimated as 88 acorns per square meter in the study site. Rate of predation including caching of acorns was highest in 1994, then declined sharply thereafter. Most of the acorns which managed to survive in the first year were predated in the second year, and only 5% of the acorns produced in 1994 survived into the third year. No seeds produced in 1994 or seedlings germinated from them succeeded to survive to 5 years after seed production. However, seedling emergence rate and seedling survival were high in the early growing season in 1995. These results suggest that predation can be a significant factor in the regeneration of Q. mongolica. and that Q. mongolica is not regenerating well in Mt. Jumbong and needs large scale disturbances for its new recruitment.

The vegetation pattern of Mt. Odae based on the soil humidity gradient showed 3 types: (1) the forest of Pinus densiflora under the mesic or xeric conditions of the low altitudinal area, (2) the forest of Acer including A. mono, A. pseudo-sieboldianum and Tilia amurensis under the submesic or subxeric conditions and (3) the forest of Quercus including Q. mongolica of the higher elevational area and Q. variabilis of the lower elevational area under the xeric condition. Water content, organic matter and total nitrogen of soil were relatively low in Pinus densiflora and Quercus variabilis communities while they were relatively high in Betula platyphylla var. japonica and Quercus mongolica communities. According to the result of cluster analysis based on similarity indices of the communities, the proposed successional sere in the forest vegetation of Mt. Odae was as follows. P. densiflora community $\longrightarrow$ P. densiflore + Q. mongolica community $\longrightarrow$ Q. mongolica + A. pseudo-sieboldianum community. P. densiflora community $\longrightarrow$ P. densiflora + Q. variabilis community $\longrightarrow$ Q. variabilis community $\longrightarrow$ Q. mongolica + Q. variabilis community $\longrightarrow$ Q. mongolica + A. pseudo-sieboldianum community.
