  • This study was conducted to investigate natural distribution of aquatic plane and to find out natural aquatic plants which highly absorb nutrient N and P. We surveyed vegetation within ${\pm}2m$ from streamside in 12 tributaries of the West Nakdong river watershed during May to October in 2003. Hydrophytes surveyed in tributaries of the West Nakdong river watershed were 27 families, 61 genera, 76 species, 3 varieties. Major dominance species of aquatic plants were Z. latifolia, P. communis, P. thunbergii, P. arundinacea, P. japonica, and P. distichum var. indutum. Aquatic plants having high production ability of biomass were Z. latifolia, P. communis, P. arundinacea, P. japonica, and E. crus-galli var. echinata. In the vertical distribution of hydrophytes within streams, dominant species were P. thunbergii and P. japonica in the upper stream, but dominant species in the downstream were P. communis and Z. latifolia. Species diversity or aquatic, plants was reduced, but their biomass and nutrient (T-N and T-P) content per the natural area unit $(m^2)$ were increased in the downsteaam. Nutrient N and P content of aquatic plants per the natural area unit were high at Joman river, Pyeonggangcheon, Bulam drainage canal, and Hogyecheon. Fifty-seven species of aquatic plants having high biomass were grounped into 4 categories $(I{\sim}IV)$ according to their nutrient content per dry weight unit. I group $(T-N,\;\geqq20gkg^{-1}\;&\;P_2O_5,\;\geqq7gkg^{-1})$ was comprised of 3 submerged plants (H. verticillata, P. crispus, and C. demersum), e emergent plants (O. javanica, P. distichum var. indutum, and R. sceleratus), 1 suspended plant (T. japonica), and 1 riparian plant (A. lobatum). Otherwise, in classification of natural hydrophytes according to their nutrient content per natural area unit, Z. latifolia, P. communis, P. longiseta, P. arundinacea, and P. distichum var. indutum possessing great biomass productivity as emergent plants were included in I group $(T-N,\;\geqq1gm^{-2}\;&\;P_2O_5,\;\geqq0.7gm^{-2})$.

  • This study examined the status of the vegetation around Gangcheonsan provincial park located in Sunchang-gun in Jeollabuk-do and Damyang-gun in Jeollanam-do from June 4 to October 12, 2011. Gangcheonsan vegetation was arranged 9 plant communities in accordance with data of 28 releves. Major forest vegetation included Quercus variabilis communityand Quercus variabilis-Quercus serrata community, Pinus densiflora community, and Pinus densiflora-Quercus variabilis community (evergreen coniferous forest in all), and Phyllostachys nigra var. henonis community (plantation). Wetland vegetation included Salix gracilistyla community (riverbank forests), Phragmites japonica community, and Polygonia thunbergii community. Gangcheonsan Provincial Park has beautiful scenery that is in harmony with fantastically-shaped rocks, waterfalls, and valleys and conserves a specific plant community habitat distributed through the forest wetlands including its valleys. It is necessary to conduct long-term monitoring with its focus on Pinus densiflora community, Lycoris koreana community, and Lycoris squamigera community in the provincial park to grasp the characteristics of ecological inhabit changes in major communities and provide active methods for conservation, restoration, and publicity.

  • 습지는 다양한 생물종의 서식지를 제공하고 있다. 습지는 물과 영양분이 충분하기 때문에 식물이 서식하기 좋을 것 같지만 실제적으로 습지에서는 잦은 수위변동이 발생하므로 습지에서 식물은 생리적으로 가혹한 환경에 처해 있다고 할 수 있다. 따라서 습지 식물은 서식하는데 있어 수위의 영향을 많이 받는다고 할 수 있으며 습지 조성 및 관리에 있어 습지 식물의 서식환경을 분석하는 것이 필요하다. 이에 본 연구에서는 습지 식물종의 특징과 최적의 생육환경과의 관계를 규명하기 위해 식생서식환경을 침수심과 연계하여 분석하였다. 이를 위해 식물 군락이 잘 발달되어 있는 남한강의 비내섬 습지에 대해 유황분석을 수행하였고, 유황에 따른 유량을 모의하였다. 모의된 유량과 HEC-RAS 모형을 이용하여 유황별 홍수위를 산정하였다. 또한 RAS Mapper를 이용하여 침수심과 침수구역을 모의하고, 이를 통해 여러 생물군 중 침수심에 영향을 많이 받는 식물의 서식환경을 분석하였다. 분석 결과, 버드나무군락은 침수가 발생하지 않는 지역 및 0~0.8m의 침수심, 물억새군락은 침수가 발생하지 않는 지역 및 0~0.4m의 침수심, 쑥-망초군락과 달뿌리풀군락은 0~0.4m의 침수심, 그리고 환삼덩굴군락은 0~0.8m의 침수심이 발생하는 지역에서 서식하는 것으로 분석되었다. 본 연구는 유황에 따른 침수심에 대한 식생서식환경을 분석한 것으로 식생을 고려한 인공습지 조성이나 하천설계에 있어 기초적인 자료가 될 것으로 기대되며 보다 더 정확한 연구를 위해서는 장기모니터링을 통한 식생 자료의 축적 및 더 효과적인 수위-식생 연계분석 방법론에 대한 연구가 필요할 것으로 판단된다.

  • The characteristic of the quality of stream water and the riparian vegetation during rice cultivation in the rural area of the eastern Jeonnam province was surveyed from April to November, 2000. The water quality of the streams during rice cultivation was variable. The pH of these water bodies ranged from $6.5{\sim}8.3$. Electro conductivity (EC) at each water body ranged from $162{\sim}4,910\;{\mu}S/cm$ for Beogyo-cheoa $114.7{\sim}286.6\;{\mu}g/cm$ for Boseong-cheon, $74.8{\sim}147\;{\mu}S/cm$ for Songgwang-cheon, and $61.6{\sim}82.1\;{\mu}S/cm$ for Isa-cheon. Total nitrogen and other parameters (K, Ca, Mg, Na, $Cl^-$, SS) were higher at May (Boseong-cheon) through June (Songgwang-cheon, Isa-cheon) during the transplanting season than these same parameters at August October and November. Thirty weed species of sixteen families were found in the survey areas of Songgwang-cheon, Boseong-cheon Isa-cheon and Beolgyo-cheon. Nine annual weeds, four biennial weeds, and seventeen perennial weeds were found, several different life forms were identified. Of those species three were submerged, two were free floating, five were emerged, and twenty were water-side weeds.

  • The aim of this study is to compare and analyze plant monitoring results of 2012 and 2013 for three artificial wetlands of Binae, Sedo, and Okpo areas in Namhan river, Keum river, and Nakdong river respectively. As the results, the Binae wetland in 2013 shows the same environment with 2012, that is, Willow and Common reed were dominant and the distributed plants in the wetland were Phragmites japonica Steud, Carex dispalta Boott, and Humulus japonicus in lowland of river side. Especially, Humulus japonicus was increased in summer season and Willow was increased in lowland of 초원. In Okpo wetland, Water chestnut was appeared in 2013 which it was not in 2012. Reed distribution was reduced in 2013 comparing to 2012 but Pussy willow distribution was not changed in 2013. In Sedo wetland, Secondary grassland was artificially planted in 2013 and so the colony was changed to Chinese Lespedeza and also most of plant colony was changed to Colt's-tail. Therefore, we can know that wetted transition rather than dried transition will be occurred in the Binae wetland. However, the Okpo wetland has monotonic change and so the transition will be proceeded with long time. The Sedo wetland showed wetted and dried transitions exist together. Therefore, the wetland will be changed to Reeds, Common reed, and Willow colonies.

  • The purpose of this study is to evaluate the channel changes according to the temporal and spatial distribution of the deposition area by the vegetation invasion in Kyesung-river. The deposition area mainly occurred by landslide and debris flow from the headwater channel. And also the movement of subsequent downstream depends upon the site of deposits by a varity erosional processes. As the age of deposition area is older, it had a tendency to stable by plant invasion relatively. The vegetations grown in deposition area were very effective to estimate a historical deformation process of river-bed occurred by landslide. The vegetations around deposition area consisted of the same as tree species grown in forest area of circumference like Pinus densiflora, Styrax japonica, Quercus acutissima and Salix gracilistyla. If the torrential stream is flooding, the deposition area of 1 to 5 years can be change to the channel easily. Deposition area of 11 to 23 years had a high river-bed because it passed long time since deposited, and amount of sedimention is much more in wide than in narrow channel. It is consider that the change of channel had many influenced by the span of survial time, scale and movement frequency of deposition area after the vegetation invasion.

  • This study was carried out to obtain basic ecological information required for wetland restoration in Korea where wetland is very deficient. To arrive at the objective, we collected the basic ecological information for wetland restoration in four Doombeongs located on Goesan of Chungcheongbuk-do (province), central Korea where maintains relatively integrate feature of Doombeong. Synthesized horizontal distribution of vegetation based on vegetation established naturally except that established by artificial interference, Potamogeton distinctus community, Spirodela polyrhiza community, Sagittaria aginashi community, Trapa japonica community, Scirpus triangulatus community, and Sparganium japonicum community, Persicaria thunbergii community, Juncus effusus var. decipiens community, Ludwigia prostrata community, Humulus japonicus community, Persicaria nodosa community, Miscanthus sacchariflorus community, Phragmites communis - P. japonica community, and Scirpus radicans community, S. gracilistyla community, Spiraea prunifolia for. simpliciflora community, and Rosa multiflora community, and Salix koreensis community and Acer tataricum subsp. ginnala community tended to be established in aquatic zone, herbaceous plant dominated vegetation zone, shrub dominated vegetation zone, and tree and sub-tree dominated vegetation zone, respectively. As the result of DCA ordination based on vegetation data collected from several Doombeongs and their surrounding areas, plant communities tended to be classified into aquatic, wetland, and riparian plant dominated stands. Spatial niche and species composition of major plant communities composing those stands were suggested as the reference information for creating ecological pond as a type of wetland. Further, the importance of wetland and the necessity of wetland restoration was discussed based on functions that the wetland displays.
