참나무류 주요 수종의 성장(成長) 및 물질생산(物質生産)을 파악하기 위하여 경기도(京畿道) 광주지방(廣州地方) 서울대학교 농업생명과학대학 부속 중부연습림에 위치하고 있는 평균 수령(樹齡) 32-38년생(年生) 굴참나무, 상수리나무, 떡갈나무, 신갈나무 등 4개 수종 천연임분(天然林分)을 대상으로 임분별 $10m{\times}10m$ 조사구 10개씩을 설치 한 후 매목조사(每木調査)를 실시하고 임분별 10주씩 총 40주의 표본목(標本木)을 선정 벌목하여 조사하였다. 평균 흉고직경(胸高直徑)과 수고(樹高)는 상수리나무, 굴참나무, 신갈나무, 떡갈나무 임분의 순으로 컸다. 임목밀도(林木密度)는 굴참나무, 떡갈나무, 신갈나무, 상수리나무 임분의 순으로 높았다. 현존량(現存量)은 상수리나무 임분 122.73t/ha, 굴참나무 임분 87.03t/ha, 신갈나무 임분 72.14t/ha, 떡갈나무 임분 38.56t/ha의 순으로 많았다. 순생산량(純生産量)은 신갈나무 임분 7.49t/ha/yr., 굴참나무 임분 6.47t/ha/yr., 상수리나무 임분 6.06t/ha/yr., 떡갈나무 임분 3.52t/ha/yr.의 순으로 많았다. 순동화율(純同化率)은 상수리나무 임분 3.275, 굴참나무 임분 2.898, 신갈나무 임분 2.888, 떡갈나무 임분 1.840의 순으로 높았다. 4개 임분의 순동화율(純同化率) 순위와 순생산량(純生産量)순위가 다른 것은 잎의 현존량(現存量)이 다르기 때문이었으며 순생산량(純生産量) 순위와 현존량(現存量) 순위가 다른 것은 지속적 축적기관인 줄기, 비교적 단기간의 축적기관인 가지, 비축적기관인 잎의 순생산량(純生産量) 구성비(構成比)가 다르기 때문이었다. Four natural Quercus stands in Kwangju, Kyonggi-Do, of which ages ranging from 32 to 38 years old, were studied to compare their growth, biomass and net production. Ten $10m{\times}10m$ quadrats were set up and ten sample trees were harvested for dimension analysis in each stand. The largest mean DBH and height were shown by Q. acutissima stand, and followed by Q. variabilis stand, Q. mongolica stand, and Q. dentata stand in descending order. Tree density was the highest at Q. variabilis stand, and followed by Q. dentata stand, Q. mongolica stand, and Q. acutissima stand in descending order. Biomass was the largest at Q. acutissima stand(122.73t/ha), and followed by Q. variabilis stand(87.03t/ha), Q. mongolica stand(72.14t/ha), and Q. dentata stand(38.56t/ha) in descending order. Net production was the greatest at Q. mongolica stand(7.49t/ha/yr.), and followed by Q. variabilis stand(6.47t/ha/yr.), Q. acutissima stand(6.06t/ha/yr.), and Q. dentata stand(3.52t/ha/yr.) in descending order. The highest net assimilation ratio was exhibited by Q. acutissima stand (3.275), and followed by Q. variabilis stand(2.898), Q. mongolica stand(2.888), and Q. dentata stand (1.840) in descending order. The difference in net assimilation ratio and net production among four stands was caused by differences in their leaf biomass. The difference in net production and biomass among four stands was due to that in the distribution of net production among stems, branches and leaves.

This study was conducted in the Chusan Area of Seoul National University Researh Forests at Kwangyang, Korea. The objectives were to compare tree growth, soil nutrient distribution and soil profiles at Pinus rigida, Pinus rigida x P. taeda, Pinus taeda and Abies firma stands. Soils were collected from each layer. The amounts of total nitrogen, available phosphorous and potassium, and soil conductivity and pH were measured. The results obtained from this study were as follows: 1. The amount of total nitrogen, available phosphorous and potassium decreased from A to B layer. 2. All soils are acidic, and soil pH increased from A to B layer. 3. The annual diameter growth rate of Pinus taeda was higher than those of other species. 4. The annual volume growth rate of Pinus rigida x P. taeda stand was higher than those of other species.

The objectives of this study were to examine the amount of nutrient input by throughfall and stemflow, and the nutrient dynamics by throughfall, stemflow and soil solution among Pious koraiensis, Larix leptolepis and hardwood forests including oaks at Kwangju-Gun, Kyonggi-Do. A total amount of rainfall during the study period was 1410.1mm. Of the total rainfall, 85% was from throughfall at the L. leptolepis stand, 84.5% at the thinned P. koraiensis stand, 83.2% at the unthinned P. koraiensu stand and 81.2% at the hardwood stand, showing greater throughfall at the conifer stand than at the hardwood stand. Stemflow showed 2.7% of rainfall at the hardwood stand, 1.3% at the unthinned P. koraiensis stand, 1.2% at the thinned P. koraiensis stand and 0.8% at the L. leptolepis stand, showing greater stemflow at the hardwood stand than at the conifer stand. Ion concentration of stemflow was greater than those of rainfall and throughfall. The conifer stand showed higher ion concentration than the hardwood stand both for ration and anion. The ion concentrations of throughfall and stemflow were higher in the descending order : NH₄^+-N$gt;K^+$gt;Ca^(2+)$gt;Na^+$gt;Mg^(2+) for rations and SO₄^(2-)$gt;NO₃^--N$gt;Cl^- for anions. After the precipitation passed through the canopy, K^+ increased most at the hardwood stand, whereas NH₄^+-N did most at the P. koraiensis and L. leptolepis stands. The ion concentration of soil solution was higher in the descending order : Ca^(2+)$gt;Mg^(2+)$gt;Na^+ for rations and NO₃^--N$gt;Cl^-$gt;SO₄^(2-) for anions. NH₄^+N and K^+ seemed to be supplied primarily from atmospheric deposition while Ca^(2+), Mg^(2+) and Na^+ from weathering.
