朴奉奎 梨花女子大學校 韓國生活科學硏究院 1971 韓國生活科學硏究院 論叢 Vol.6 No.-

This study was conducted from May, to Octerber, 1970, in native grassland of DonbuMyon, Kawangki-Kun, Kyungki-Do where seconday succession was taken place. This survey adopted systematic sampling method and sampled 20 of 1×1 sq. m, twelve times. In each investigation, Coverage, Frequency, Height, standing crop and dry matter weight of each species of each organ were analyzed. The results are as follows:1) The main herbs in the native grassland shows peculiar mode according to the season and they should be recognized as Miscanthus sinensis-Arundinella hirta association by coverage and frequency. 2) The stratification by the height were divided into upper layer plants, middle layer plants and lower layer plants. 3) Terrestrial standing crops of each main herbs are as follows respectively. Miscanthus sinensis.....15.7±12.5-283.2∼76.5g/m^2 Arundinella hirta.....10.6-91.6g/m^2 Erigeron canadensis.....4.1±1.1-99.7±38.7g/m^2 Carex lanceolata.....2.0-19.0g/m^2 each plant groups are follows. Poaceae.....35.3±13.7-427.1±88.2g/m^2 Camposite.....6.4±5.5-65.5±33.8g/m^2 Leguminosae.....8.2±1.6-146.2±92.6g/m^2 Cyperacea.....4.0-31.6g/m^2 Other herbs.....4.4-65.4g/n^2 Total standing crop.....54.3±11.8-723.5±54.4g/m^2 4)The peaks of the dry matters weinght by the each stratum are as followa Upper layer plants.....190g/m^2(middle of July) Middle layer plants.....70g/m^2(latter fo June) Lower layer plants.....30g/m^2(latter of June) Total dry matter werght.....480g/m^2(middle of June) 5)Dry matter production rates of each statum are as follows. Upper layer plants.....29.1g/m^2-49.7g/m^2 Middle layer plants.....5.1g/m^2-16.1g/m^2 Lower layer plants.....5.8g/m^2-6.4g/m^2 Total dry matter.....38.2g/m^2-65.5g/m^2 Dry matter production rates of the total dry matter weight and upper layer dry matter weight were presented two peaks during the growing season. 6) Relative growth rate of middle layer plants were hight value during the early growing period, but they were negative value fiom the latter of August and the of upper layer plants were holdㆍa stable value from the early of May to the latter of Oct unchangeably and that of lower layer plants, there were undulation,so they showed negtive value Twice. Thus,the growth of middle and upper layer plants were vigorous before the stratification were developed. 7) Net assimilation ratio(NAR) were appoximate with the relative growth rate, Thus, if the crown of upper layer plants predominates over that of middle laver plants, Sructure of communities are almost completed. Upper layer plants are possible to make the fine matterial production, as middle and lower plants shows decreasing quantity of penetrative light, NAR of middle layer plants lowered steadily after June, and the lower layer plants lowered much more than the middle layer plants. 8) Main herbs were divided into six thpes by c/f ratio. A type.....Arundinella hita Lespedeza bicolor B type.....Miscanthus sinensis C type.....Lysimachia barystachys Artemsia reisreana D type.....Cymbopogon goeringii E Type.....Pottemtila freyniana F type.....Carex lanceolata The F/C ratio by the stratum are as follows respectively. Upper layer plants.....Moer than 1.0 Middle layer plants.....0.5-1.0 Lower layer plants.....less than 0.5 9) On the distiribution rate of dry matter productions, in upper layer plants, the dry matters were increased from leaf parts to stem parts, thus the herights elongated,So opper pates of communities were occupied, leaf parts were concentrated od the lower layer plants, middle layer plants were little changed in distribution rates of leaf parts and stem parts from the latter of May to the latter of June.

朴奉奎 梨花女子大學校 韓國生活科學硏究院 1973 韓國生活科學硏究院 論叢 Vol.10 No.-

著者는 1972 : 4월부터 1972년 10월에 걸처서 3個地所(약간 濕한곳, 中性地, 乾性地)에서 主要草地의 地下部生態에 관한 조사결과는 다음과 같다. 1) 한국의 主要草地(억새-조릿대 군집, 억새-고사리 군집 보리사초-갯멧군집)에서 억새, 새, 잔듸, :, 고사리, 조릿대, 보리사초의 根系에 差異가 있었다. 2) 吸收系로서 각 種別로 地下部의 深度에 差異가 있었다. 3) 地下部 根群의 ecological Niche difference를 認知할 수 있었다. 4) 각 種別의 root pattern에 있어서 각 조사지소 마다 토양단면층, 根系, 根莖 과 뿌리의 重量比, 뿌리의 數에 있어서 뚜렷한 分化度를 나타냈다. 5) 地下部 生産構造는 地下 10cm 內外에서 높은 値를 나타냈다. 6) 토양환경요인이 각 조사지소 마다 뚜렷한 差異를 나타냈다. 즉 지하부의 生態的變移는 立地의 토양환경요인의 勾配와 밀접한 관계가 있어 地下部의 分化度에 差異를 가져왔다고 사료된다. Ecolgical studies of the underground part on the main grassland vegetation (Miscanthus sinensis-sasa purpurance Community, Miscan-thus sinensis-pteridium aquilinum Communty, and carex Kobomugi-Calystegia Soldamella Community) were caried out from April, 1972 to October, 1972 at three sites (a little wetted, neutralized soil, and sand ydune). The results obtained are as follows; 1. The distribution pattern of the root system of the most prominent herb's (Miscanthus Sinensis, Arundinella hirta, zoysis japonica, Imperata cylindrica, Pteridium aquilium, sasa purpurascens, and Carex Kobomugi) were observed. 2. Considerable differences in the depth in which the root system went among the most prominent herbs as well as differences in the absorption system at each of the sites was observed. 3. Ecological niche differences of the umderground root's of the different herbs can be recognized. 4. The root patterns of the main herbs showed a distinct degree of differentiation in the root system, the weight ratio of the rhijomes and roots, the number of roots, and the soil profile at each of the sites. 5. The productivity of the underground part showed the highest numerical value at the depth of 10 cm. 6. There were many differnces in the soil elements among the three investigated sites. There was a high correlation between the soil environmental elements and the root patterns at each of the sites. It has been found that there were differnces in the degree of differentiation of the underground part related to the soil environmental gradiant.

祝靈山의 새(Arundinella hirta)가 優占되어 있는 群集의 微分布와 種間相關

朴奉奎,趙恩姬 梨花女子大學校 韓國生活科學硏究院 1982 韓國生活科學硏究院 論叢 Vol.30 No.-

축령산에서 두 지역을 택하여 우점종인 새와 아우점종인 억새, 원추리, 진퍼리새, 벌깨덩굴등을 대상으로하여 미분포분석과 종간상관 분석을 하였으며, 이같은 방법으로 여러 토양요인들을 분석하고, 이들 요인들과 각 식물의 미분포와의 상관관계를 분석하였다. 새는 4가지의 미분포양식을 나타내었고, 지하경으로 성장하므로, 이것은 군집내 아우점종이 형태적 미분포를 나타나게끔 하는데 일역을 한 것으로 생각되었다. 토양요인은 좁은지역에서도 불균질하게 나타났으며, 특히 1.6㎝, 3.2㎝ 폭을 지니고 불균질하게 나타난것이 가장 많았다는 것을 알 수 있었다. 새와 억새는 전체적으로 분리되어 생육하는 경향이 있었으며, 특히 20㎝폭에서는 토양의 치환성칼슘 함량으로 인하여 공간적으로 분리되어 생육하고 있다고 생각되었다. 억새와 원추리는 160㎝ 폭에서는 공존하고 320㎝ 폭에서는 생육하고 있었으며, 이는 토양의 치환성칼륨 함량으로 인한 것으로 나타났으나, 이처럼 큰 block크기에서는 치환성칼륨만이 제한요인이라고는 생각되지 않았다. 진퍼리새와 벌깨덩굴은 전체적으로 정상관을 나타내었으나, 그 요인은 알 수 없었다. Two different herb communities dominated by Arundinella hirta were investigated using pattern and covariance analysis within Mt. Chukryung. By means of the same techniques correlations of soil properties with herbs were also examined. The results are as follows. 1. The annual increment of rhizome growth in Arudinella hirta and Miscanthus sinensis was estimed to be about 20㎝, respectively. 2. The dimension of complete rhizome system in Arundinella hirta, Miscanthus sinensis and Hemerocallis fulva was estimated to be 80-160㎝, 40-80㎝ and 80㎝, respectively. 3. Arundinella hirta had a negative tendency to associate with Miscanthus sinensis at 20㎝ scale, since rhizome of Arundinella hirta which was in high exchangeable Ca^++ was observed to be spatially excluded from that of Miscanthus sinensis. 4. Arundinella hirta was associated with Hemerocallis fulva at 160㎝ scale but negatively associated at 320㎝ scale. 5. In general, Molinia japonica was positively associated with Meehenia urticifolia but factors were not detected.

朴奉奎,韓珍順 梨花女子大學校 韓國生活科學硏究院 1978 韓國生活科學硏究院 論叢 Vol.20 No.-

1977년 7월 13일∼21일에 걸쳐 이화여자대학교 구내의 야초지에서 식물종간의 상관곤계를 밝히기 위하여 20 relve´를 설정하여 각 relve´에서 계통적인 방법에 의하여 5개 quadrat를 조사하여 총 100 quadrat를 조사하였다. 이 조사에서 Agnew(1961)의 통계분석방법으로 x^2를 산출하여 ordination을 결정한 결과는 <Fig. 3>과 같다, 이 도형에서 (1) 산초나무 (Zanthoxylum schinifolium Sieb. et Zucc.), 새 (Arudinella hirta (Thuberg) C. Tanaka), 댕댕이덩굴 (Cocculus trilobus (Thunberg) D.C.) 그룹; (2) 개여귀 (Polygonunm longisetum De Brayn), 바랭이 (Digitaria sanguinalis), 강아지풀 (Setaria viridis (Linne) Beauv), 질경이 (Plantago asiatica Linne) 그룹; (3) 매듭풀 (Kummerowia striata), (Thunberg Schindler) 차풀 (Cassia nomame Sieb. et Nakai), 쑥 (Artemisia asiatica Nakai) 그룹등 3그룹으로 대략 구분되었다. 이 세 그룹은 또한 환경구배와 상관이 있음을 인지할 수 있었다. 3그룹간의 식물들이 soil pH와 상관이 있었다. 즉 (1) 그룹은 강산 (2) 그룹은 중성과 염기성 (3) 그룹은 약산성이었다. 그러나 토양의 함수량, 최대용수량, 유기물에서 유의성을 찾아볼 수 없었던 것은 인위적인 교란으로 인한 환경적 불연속 때문이라고 사료된다. Relationships between species pairs in the native grassland vegetation of Ewha Womans University campus were investigated from July 13 through July 20, 1977. Twenty relve's were selected, each being divided into 5 quadrats, and thus 100 quadrats were served in total. The results (Fig. 3) were analyzed by Agnew's statistic method (1961), and the following conclusions were obtained. (1) The species examined can be subdivided into three groups according to the re-lationships; (1) Zanthoxylum schinifolium Sieb. ex Zucc, Arundinella hirta (Thunberg) C. Tanaka, and Cocculus trilobus (Thunberg) D.C. group; (2) Polygonum longisetum De Brayn, Digitaria sanguinalis, Setaria viridis (Linne) Beauv, and Plantago asiatica Linne group; (3) Kummerowia striata (Thunberg Schindler), Cassia nomame Siev. et Nakai and Artemisia asiatica Nakai group. (2) The relationships are correlated with pH of soil; (1) Strongly acid (2) Neutral and Mildly alkaline (3) Medium acid. (3) However, the relationships are not correlated with water-content, maximum water holding capacity and mineral content of soil probably due to environmental discontinuity by human interference.

石灰岩地帶에 있어서의 黃化現象의 頻度 및 土壤要因에 對하여

朴奉奎,吳智泳,金珍 梨花女子大學校 韓國生活科學硏究院 1972 韓國生活科學硏究院 論叢 Vol.9 No.-

原州, 寧越, 堤川의 石灰岩 地域에 나타나는 植物의 黃化에 對하여 그 出現頻度와 原因을 調査하였다. 黃化를 일으킨 植物은 62種(表Ⅲ)에 달하였다. 黃化率은 季節的 差異를 나타내는데 韓國에서는 7月, 8月에 가장 出現率이 높았다. 黃化의 原因중의 하나는 土壤의 높은 pH(7.2~8.0)로 因하여 P, Fe等이 不溶狀態로 되어 뿌리에서 吸收하기 어려워져서 생기는 現象으로 生覺된다. 黃化는 위의 元素를 水溶液의 形態로 주거나 또는 Soil pH를 6.8 以下로 處理하면 극복시킬 수 있다. Lime-Chlorosis has been noticed in plats growing in calcareous soils. Symptoms of chlorocis appeared in sixty-two species in the study areas. Lime-chloresis was currelated mainly with soil moisture and soil pH. The lack of available P and Fe in lime soils of higher pH, in which the mineral elements are in ins luble form, was the main factor for the chlorosis.
