  • To have more insight into the nature of plant, plant scientists carry out phytosociological studies on such plant species. The phytosociological studies on Tridax procumbens. Linn was carried out at Imo State University, Owerri, Imo State between the months of July and September, 2018. Tridax procumbens Linn grows abundantly in the areas under tropical climate and supported by a sandy-loam soil. Morphological features showed a range of variations. Phytosociological investigation showed a Tridax- Mitracarpus-Digitaria plant community. Tridax procumbens was positively associated with Digitaria horizontalis, Mitracarpus scarber and Vernonia cinera. The Inter-relationship of T. Procumbens was thus determined. This study therefore is a contribution to the general ecology of the plant. Phytosociological studies helps plant scientist to have more knowledge into the nature of plant species. This study is a contribution to the general ecology of the plant Tridax procumbens. The study also shows that it has close association with mitracarpus Scarber and Digitaria horizontalis. More work should be carried out to find out if these plant species flower and produce seeds at the same time or not.

  • 본 연구는 우리 나라 낙엽 활엽수림의 대표적인 수종인 신갈나무림을 분류하기 위하여 강원도 오대산, 점봉산 및 중왕산의 자연 식생 중에서 100개소를 조사하였으며, 식물사회학적 방법과 TWINSPAN에 의하여 군락을 분류하였다. 1. 신갈나무림을 식물사회학적 방법으로 분류하면 신갈나무-당단풍 군락군의 신갈나무-까치박달나무군락, 신갈나무-당단풍 전형 군락, 신갈나무-생강나무 군락 및 신갈나무-분비나무 군락으로 구분되었으며, 신갈나무-까치박달나무 군락은 다시 복장나무 하위 군락 및 전형 하위 군락으로 구분되었다. 2. TWINSPAN에 의하여 분류하면 신갈나무-복장나무 군락, 신갈나무-까치박달나무 군곽, 신갈나무-당단풍 군락, 신갈나무-생강나무 군락, 신갈나무-분비나무 군락으로 구분되었다. 3. 식물사회학적 방법과 TWINSPAN에 의한 군락 분류는 일치성을 보이고 있어 두 방법에 의한 군락 분류 방법은 상호 보완될 수 있다고 사료된다.

  • A phytosociological study of forest vegetation of Mt. Kaya was carried out from August 1988 to September 1992. The forest vegetation of the area was classified into 3 communities (Quercus monogolica community, Lindera erythrocarpa community, Pinus densiflora community) and 3 subunits (Rhododendron mucronulatum subunit, Platycarya strobilacea subunit, typical subunit of Pinusdensiflora community). The Pinus densiflora community was located at the lower altitudes (100~300m) than those of other communities. The Lindera erythrocarpa community was located at the upper altitude (500m). Most of the inverstigated area were occupied by the secondary forest of Pinus densiflora community in the actual vegetation map and the profile diagram, suggesting that it was frequently destroyed by human interference

  • This study was carried out to investigate the phytosociological method for analyzing vegetation composition, which would be one of the major keys of land use in Sinchun stream side-bed. The obtained results were as follows As the result of survey, following flora were observed. Most of plants composed of Graminea,Compositae, Leguminosae and Poligonaceae, 23, 17, 13 arid 9 species, respectively. In upper stream side-bed, E crus-galli var. caudata and Phragmites communis were well growed,which were effective for cleansing water. Otherwise both Polygonum species and Rumex were profused in Mid-stream side-bed and Down-stream side-bed, these plants were well growed in polluted stream. Key words: Phytosociological, Polluted stream, Sinchun stream side-bed, Taegu city.

  • Phytosociological investigation of the forest vegeation was carried out in Kumo archipelago at the period of May 21th 1990 to May 29th 1990 by Braun-Blanquet's method. The forest vegetation was classified into 7 communities, Camellia japonica, Castanopsis cuspidata var. sieboldii, Machilus thunbergii, Camellia japonica-Pinus thunbergii, Camellia japonica-Torreya nucifera, Carpinus coreana and Quercus acutissima community. Based on the classification of communities, the actual vegetation maps were drawn in 1 : 50,000 scale.
