  • 1996년 2월부터 8월까지 총 3회 11일간 설악산 국립공원 외설악과 인근지역의 관속식물상을 조사한 결과, 101과 379속, 659종, 2아종 105변종 8품종 총 774종류(taxa)로 조사되었다. 이중에서 외설악 지역에는 89과 321속, 526종 2아종 89변종 3품종중 총 620종류(taxa), 점봉산 지역은 86과, 251속, 350종, 1아종 51변종 2품종 총 404종류(taxa)로 각각 조사되었다. 외설악 지역에서는 남쪽에서 자라는 개족도리와 대팻집나무의 자생지를 확인하였고, 점봉산 지역에서는 신포동의 산외, 관모봉 지역에서는 참배암차즈기 등 6종류의 희귀식물을 발견하였다. 확인한 북방인자의 식물로는 분비나무, 눈잣나무, 눈측백, 등대시호, 두메부추, 금강봄맞이, 만주송이풀, 말나리, 붉은인가목, 솜다리, 톱바위취 등 17종류, 남방인자의 식물로는 사람주나무, 대팻집나무, 때죽나무, 지리대사초, 개족도리, 암대극등 6종류로 조사되었다. 또한 겨울철 도로교통의 안전을 위하여 뿌린 바닷가 모래의 영향으로 갯씀바귀, 갯완두, 참골무꽃, 해당화 등 해안지역에 주로 생육하는 식물이 도로를 따라 산악 내부까지 침투하고 있음을 확인하였다.

  • 한국은 삼면이 바다로 되어 있어 염습지와 이에 인접한 해안사구가 발달되어 있다. 본 연구는 한국 서·남해안의 염습지와 사구에서 나타나는 염생식물의 군집과 식물상의 특성을 48개 지소의 571 식분에서 조사하고, 분석하여 연안 생태계의 특성을 밝히고자 시도하였다. 그 결과, 염습지에 분포하는 식물군락은 39개이었으며, 갈대군락의 분포면적이 가장 넓었고, 버들명아주군락이 가장 좁았다. 나문재군락이 해안선으로부터 가장 근접하여 분포하였고, 해홍나물군락이 해양쪽으로 가장 멀리까지 분포하였다. 해안사구에 분포하는 식물군락은 29개이었으며, 갯그령군락의 분포면적이 가장 넓었고, 수송나물군락이 가장 좁았고, 갯메꽃군락이 해안선으로부터 가장 근접하여 분포하였고, 해당화군락이 내륙쪽으로 가장 멀리까지 분포하였다. 염습지의 식물상은 6과 14속 17종 1변종 18분류군 이였으며(식물구계학적 점수; 16점), 해안사구는 11과 18속 20종 1변종 21분류군(식물구계학적 점수; 34점)으로 해안사구가 염습지 보다 약간 높게 나타났다. 이러한 결과는 한국 서남해의 연안에서는 해안사구가 염습지보다 해수의 영향을 간접적으로 받기 때문에 염도에 약한 식물도 생육할 수 있기 때문으로 해석된다.

  • A floristic study on the diatom was carried out in coastal area at two seasons, August 2014 and April 2015, from three islands in the northern area of Yellow Sea of South Korea. A total of 117 species of diatoms, including 3 classes, 9 subclasses, 20 orders, 32 families and 54 genera, were identified based on LM and SEM examinations. Three species of diatoms, Gyrosigma obscurum, Pleurosigma frenguellianum, and P. sabangi were newly recorded in Korea. The historical synonyms of the species are presented for the floristic informations, the examined specimen for the each taxon is specified, and the distribution in three islands and detailed sampling localities of each taxon are given.

  • While conducting a floristic study of Korean hepatics, we discovered two unrecorded species, which were collected from wind holes near the Donggang River, Korea. Mannia fragrans (Balb.) Frye & L. Clark and Mannia androgyna (L.) A. Evans are hereby reported for the first time in Korea. M. androgyna is characterized by pale grayish oil bodies in both the aerenchyma and basal tissue, and saccate spores with a conspicuous proximal disc. M. fragrans is characterized by a gynoecial segment with a whitish apical brush of scales, a commonly aromatic smell, and areolate spores with a conspicuous proximal disc. Two unrecorded species are described and illustrated based on Korean material.

  • A study on indigenous diatoms was carried out at 10 sites from May 2014 to December 2016 in marine and freshwater in Korea. Seventeen species of diatoms are new to Korea and they are divided into 3 classes, 4 subclasses, 10 orders, 14 families, and 16 genera. The nomenclatures, references, dimensions, specimens examined, local habitat, distribution in Korea, and photograph are reported here. Seventeen species found in marine, freshwater, and brackish water showed species-specific habitats.

  • The present study summarizes the occurrence, distribution and autecology of 12 taxa of the class Cyanophyceae collected from several swamps, reservoir and highland wetlands in South Korea from 2009 to 2012. A new species, Anabaena koreana sp. nov. and 11 taxa of blue-green algae newly recorded are described and illustrated. Anabaena koreana is similar to A. oumiana, A. spiroides and A. crassa in that the trichomes form regular coils. However, A. koreana is distinguished from these three species by the morphological characteristics of the vegetative cell, heterocyst, and akinet shape and size. This study considers 12 blue-green algal species, including a new species, Anabaena koreana sp. nov. and 11 species that are recorded for the first time in the Korean freshwater algal flora. Among them, the genus Nostochopsis Wood ex Bornet et Flahault 1886 had not previously been recorded in Korea.

  • Bowlesia incana Ruiz & Pav., a new invasive alien plant in Korea, was found in Ulju-gun, Ulsan Metropolitan City. This species is characterized as being similar to the genera Hydrocotyle Tourn. ex L. and Centella L. However, it differs morphologically from these two genera in leaves, flowers, and fruits, as well as stellate pubescence growing on the whole plant. In Korea, Bowlesia incana Ruiz & Pav. is recorded for the first time in this study. A morphological description, distribution map, and illustrations based on the Korean materials collected are presented.

  • A study was performed to examine the soil environment, vegetation type to the inside slope of sea dike. The soil pH was about 8.5, electric conductivity was $4.59dSm^{-1}$, soil strength was 12.1mm, organic matter was 0.21%. The vascular plants of the inside slope of sea dike were consisted of 101 taxa such as 26 families, 80 genera, 93 species, 8 varieties, 1 hybrid. The life cycle of the plants was annual 38.6%, biennial 14.8%, perennial 46.5%. As it compared with consistency ratio in the flora of korea, the distribution of annual, biennial appeared highly. From this examine, it appears that the environment need soil improvement using water holding materials and organic supplements.
