本調査는 1974年 8月 1日∼8月 7日에 실시했다. 1. 重要値를 가지고 12개의 主要 種集團을 抽出했다. 2. 主要 種集團의 分布城은 濕度勾配에 따라서 크게 영향을 받는다. 3. 主要 種集團의 分布城은 高度勾配에 따라서 크게 영향을 받는다. This paper presents major species population extracted by the importance value (100X100sq.m) along topographic moisture gradient from moist environment of ravines to dry environments of south-facing slopes. The broad overlap and scattered centers of species population along a gradient imply that most communities intergrade contiuously along environmental gradient, rather than forming distinct, clearly separated zones. Apart from the canyons, forests form a series a zones in response to moisture conditions related to elevation. At a given elevation north-facing slopes and canyons are cooler and more humid while south-facing slopes warmer and more aried. Community and soil characteristics show patterns in relation to the pattern of environments.

This is report on the cover degree,frequency, height, and standing crop of the tall grass type, measurd by the systematic sampling method which applied 44 tall grass type sites in Korea, ten IxIm. sq. were taken each of them, during the interval 69.5-69.10.30. The present study investigated PH. water content, Humus as the soil element, and warmth index as the climatic elements. The survey of result is like following. 1. ◁표 삽입 ▷(원문을 참조하세요) 2. The growing-period of tall frass type is under the great influence of fresh weight of the Korea native grassland by the limiting factors of climatic elements (temperature, precipitation, etc.) And also demolition of the soil formation process, caused by the biotic factor, results in the decrease of the fertility. 3. There is a tendency that the more moderation of the biotic factor is increase. the less SDR,RD, weinght, and height of Miscanthuns are decrease, and on the contrary, community components is increase. 4. Accrding to constancy, sequence of the sort whose treuegrad is high are Pteridium, Artemisia, Arundinella, Lespedeza. And Sasa is distributed in the large forest floor of Quereteum, and it's in inverse proportion to succession sere of Miscantheum. 5. We could find that amount of production was decrease in proportion to modal-D.S of Miscanthus type grassland. 6. The relations between D.S and RD, and D.S and IGC are positive and negative correlation on modal D.S. 7. We can determine the positive negative ecological distance on typical status of Miscanthus type vegetation as a standard.And ecological status of the Miscanthus type vegetation can be assumed. 8. At the Miscanthus type grassland, the continnum of the succesion sere could be recognized, and we found a remarkable tendency in the fact that the weight ratio of each main herbs showed a curve of increase-peak-decrease according to D.S.And on each site of the modeal-D.S appeared distribution area respectively. 9. In the measurement of the percentage of appearanc site of soil element and of Miscanthus type site, the PH got the highest value at 6.0%, soil content at 5.00%, and Humus at 3.00% respectively. And soil element and RD had positive and negative corrlation. 10. It's Seemed that the grassland productivity is deeply related with warmth index, horizontal change and vertical change are considered to be caused by the difference of growing-period.

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.
