1) 傾斜角이 50°以上이 되면 土粒 石塊, 枝葉의 停滯堆積이 不能하여 種子 肥子의 散布가 되어서 이 地域에 固着할 수 없어서 植生群落의 發達을 볼 수 없다. 2) 隣接地에서 根莖에 依한 Poaceae. 匍匐하는 칡, 댕댕이덩굴 等이 傾斜面의 固圍에서 侵入한다. 3) 比較的 濕한 斜面에는 이끼 種類가 出現하여 1㎡~2㎡의 群落을 이룬다. 4) 多少라도 傾斜面에 凹入部가 생기면 種子 胞子의 停滯固着이 이루워져서 여러 植物體의 出現을 볼 수 있다. 5) 砂礫層은 侵蝕壞崩하는 것이 빠르기 때문에 埋木層 凝灰岩이 突出하여 이 上部는 凹部가 되거나 또는 部分的으로 새로운 土砂粒子가 停滯堆積하게되어 他植物의 固着을 許容케한다. 6) 露出한 岩石에 間隙이 생기면 여기에 他植物의 繁植을 볼 수 있다. 7) 同一한 斜面에서도 部分的으로 傾斜角度가 다르며 여기저기 凹部가 있어 이런 곳에 侵入한 植物은 不安全하며 降雨에 依해서 上部에서 土砂가 轉落하여 崩壞시킨다. 8) 傾斜角 75°以上에서는 植物의 繫盛을 볼 수 없다. 9) 土壞이 傾斜面上에 停滯할 수 있는 最大의 角度는 土壞의 種類 含水量 斜面의 方位其他에 依해서 다르지만 여러 번의 野外觀察로 서울近郊에서는 40°前後인 것 같다.

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.

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.

韓國의 草地地下部의 生態에 관한 硏究

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.
